RVS 4000 on Port 587

hi
I just bought RVS 4000 a week ago. My previous router can send email through port 587,
Ever since i bought RVS 4000, it stop sending emails. I opened port 25 and I have tried all my best to do port forwarding to port 587 but still it cannot send email.
My ISP is using port 587.
Please help help me on this. What should i do to be able to send email on port 587?

Hi Lui,
When you say send mail on port 587, are you referring to sending mail from the LAN to the WAN on port 587? Or a port forward translation from 25 on the WAN to 587 on the LAN?
On the RVS4000, you can perform port translation by going to the Firewall Page, then Single Port Forwarding. Create an application name (text based, will not affect config) and then you can choose an external port to internal port. Lastly point to the internal IP address of the mail server.
If you are referring to sending mail on port 587, the router is by default going to allow all outbound traffic out and will not block or filter ports.
Please let me know if this resolves your issue.
Thanks!
Dave

RVS 4000 HTTP mgmt interface hangs @ Port 80 & DHCP stops working

This is the RVS 4000
Firmware version 1.3.3.5
STAR 9202 Chipset
64 MB DRAM
8MB Flash
DOS, Block WAN Rq, Remote mgmt all OFF
IPSec Tunnel none used
Internet connection is DHCP
LAN is set to DHCP with several Static devices defined
DMZ is dsabled
Functionining as a gateway
Time is set via NTP & the NRC
IPV4 Only
Everything is pretty much dedault except for QoS
Trust mode is Port, set to 4, 4, 4, 1
( Port 4 has a Linksys ATA plugged into it for VOIP services )
SIP Port Forwarding is enabled for 5060
Every day or so the Router becomes unresponsive to the HTTP mgmt interface, as well as it no longer offers DHCP services.
When this happens the only remedy is to power reboot.
Everthing comes back online just fine, however, the LOGS are initilaized so no data to figure out what`s going on.
My next step is to setuo a syslog server and have the logs copied out.
Anyone see this kind of behavior before ?
Any ideas ??
( No, I have no Torrents running at all, but I do have several devices like AppleTV, PS3s etc that run streaming Video plus I have the SPA3102 )
Thanks Derek

Hi there Vijay !
I cannot upgrade to that version of Firmware as my RVS4000 is a V1, not a V2.
Is there some way I can change it such that it will load the newer Firmware ?
This is the error I receive when trying to upgrade anyway :
"Upgrade file is not the correct type or version for this device.
Upgrade failed.
Please obtain the correct file and try again."
Otherwise the newest firmware I can load is 1.3.3.5
( which seems to have this problem )

Yes, I posted this same information in the Video Surveillance section a few weeks ago. it was actually a Partner on the
community who found this and brought it to our attention and we fixed it.
Thanks for cross posting here, since you are right in it also effected this router.
And a big thank you for taking the time to collaborate some very useful information with the community. I have noticed your recent posts and I think they are well writen, helpful, and well organized. I also like your idea of turning some threads into solutions documents and resource labs perhaps.
If you would ever like to post something of that natire, you may also. Just creat a document with your findings.

RVS 4000 Drops LAN devices

I recently updated my network with the following:
RVS 4000 v1.3.2.0 - Linksys by Cisco version
SG200-26
AP541N [WAP]
All devices have the latest version of firmware.
Users only connect laptops via wireless, they are a mix of MAC and Windows users, devices such as printers and network storage are all wired connections.
The RVS 4000 would drop the internal Lan after several hours or sometimes days, there would be no reason to the periodicity it would retain and then drop the LAN. By dropping the Lan I mean:
Internet Access would cease, devices such as laptops would lose their wireless connection, a laptop requesting an IP address would be ignored. Effectively we were down.
Connecting a laptop to the network via a cable connection would eventually get an IP address but all other wired devices such as the NAS Storage and printers would be unreachable and require powering off and on to get an IP.
A reboot of the RVS 4000 by powering off the router would have to happen to restore the LAN quickly. I followed advice on the Internet and this forum by upgrading the firmware and resetting to factory defaults and then reloading the configuration.
The only change that seemed to make any sort of differnece was connecting the AP541N directly to the RVS 4000 rather than the SG200-26. Throughput increased and the period between LAN drops extended but the RVS 4000 would ciontinue dropping the LAN eventually.
When it dropped the LAN during a work day, that was it!
I read a lot of negative feedback on the version of RVS 4000 firmware and as the version 2.0 will not install I purchased the Cisco version of the RVS 4000 v 2.0.0.3.
The new RVS 4000 also drops the LAN! The period between drops is much longer, but it still drops the Lan.
Ventilation is good and it is sitting on its edge using the platsic feet that come in the package.
The AP541N is still directly connected to the RVS 4000 rather than the SG200-26.
Any ideas on how to fix the RVS 4000 or an alternative... I would like to stay with Cisco, an alternative, if the RVS 4000 is unfixable should have a browser based admin facility!
Thanks

Mark,
Very strange behavior; it would seem with the earlier version and new version of the RVS4000.That this will be more an environmental issue. Now trying to find out what is causing this type of behavior. Need some logs from the router and the SG200 switch before any reboots. If you have the ability to set up a syslog server and capture this information would be great. Also detail information on what port each device is plugged into. Hopefully from this we can tell what might be happing in your network to cause this type of behavior.
Jarkko,
Your issue sounds like you have a default ip address conflict, this usually happens when you leave the default ip address of RVS4000 to 192.168.1.1 and many times modem are hard coded with a similar address of 192.168.1.1, which can cause the type of behavior I have seen the in past.
Also I would leave IPS enable unless you are trying to reach download speeds above 20Mbs
Thanks,
Hope this helps.

RVS 4000-V2: PPPoE failed - "unrecognized option '1492'

I've got a brand new RVS 4000-V2 router (firmware: Release 2.0.0.3)
Can't get a connection to my ISP using "Internet Connection Type" PPPoE.   The connection works fine with any other router.
MTU size is set to "auto".
Logfile says:
Plugin pppoe loaded
PPPoE Plugin Initialized
Plugin pppoe called.
unrecognized option '1492'
I use the standard Web-administration client.
Any ideas?

Thanks
for the reply.
In the meanwhile I've tried it with another DSL-Modem - same effect: No connect to the Internet-Provided
,    "unregognized option '1492'" in den Log-File.
I have no problems with the Internet Connection using a differend router from another brand with both of the modems (Siemens Plus or D-Link DSL 321B).
I have attached a screenshot of the WAN settings as requested.   I tried both the auto and the manual mode. No success.
If you give me directions how to trace the WAN Port with your router, I would do so.
Best regards

Connecting 3 RVS 4000 with VPN

Hello,
i want to connect in a triangle 3 RVS 4000 Router with VPN
i have configured 3 routers, which are able to connect to the Internet. Each of them are configured as a gateway.
i have created 2 tunnel on each router. But the vpn connection can't be established,
here is the configuration of router1 the other are configured in the same way, only the remote group setup is different
Do i have to open also some ports for the VPN , if yes which one and were
Thanks fpr your help and response
HP.Meyer

Hello,
Are you trying to ping the IP address of the clients behind the routers or the computer name? You will need to use the IP addresses only unless you add the names to the LMHOSTS file in your PCs. Also, if there is any antivirus or third party firewall software running on those clients it will block the PC from replying to pings from an untrusted subnet. For example you ping from R1 with 192.168.100.1 to a PC behind R2 that has 192.168.101.x. Because the antivirus or firewall software on the PC sees that the ping request is coming from a different subnet it will block the response. You will need to either disable any security software or add the untrusted subnet to the trusted list in that software. Sometimes it is best to test by pinging something that does not have any software, such as a printer or print server.
Please keep us updated.

RVS 4000 DDOS Attacks

Hello!
Since I got a NAS System connected to my Network (one Month ago) I get attacked every day by DDOS attacks.
I Just set my NAS to the DMZ of my Router and opened 3 Ports for Service of QNAP.
I assume that at this moment I got scanned and thererfore the intrusions started.
For the last month I experianced nearly every Day Internet Connection Problems and the Router didn't respond anymore.
As I found last week a new Firmwar-Version I updated my router, enabled IPS and applied the latest Security file.
In the IPS Report I found loads of DDOS and Synflood attacks.
With IPS my Router Works and I got no more problems that my Inet access is corrupted BUT now I got the Problem that my
downloadrate sunk to 20Mbit from formerly 100Mbit.
I already wrote my ISP about this situation and want them to change my WAN-IP Adress but they to it only in very urgent cases.
Is there any option to operate the RVS 4000 save AND fast???

Sorry I seem to have no access to the documentation,

Cannot send email via Hotmail through port 587 with Secure Connection (SSL) set

Something is blocking my attempts to send email (with Outlook Express) via my hotmail.com account. The error I receive is as follows:
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'Hotmail', Server: 'smtp.live.com', Protocol: SMTP, Port: 587, Secure(SSL): Yes, Error Number: 0x800CCC0F
When Hotmail.com first changed over to a POP3 server (Sept 2009), I could send emails through them using port 587, which they require. But then something happened, with no changes on my part, to disable my ability to send.
I have checked and rechecked my Outlook Express account settings. I can send email through another third-party mail account (at 1&1 Internet.com) using port 587, which does not require setting SSL to yes. I can also ping the Hotmail SMTP server via port 587 and receive a response from it.
I connect to Verizon DSL via a Westell 327W modem/router. Clearly it is not blocking port 587 without SSL. Does it have the capability to block SSL traffic? Or is the Verizon server the culprit, not allowing emails to be sent via Hotmail.com?
Two different computers on my LAN have the same problem sending emails via Hotmail.com. I have tried everything the Hotmail people have suggested; at this point they think it is an ISP problem, hence this post. This problem doesn't make sense to me and is driving me crazy. Can anyone help me with this?
Thanks.

You can still have your reply address set to your hotmail address. And you don't have to really remember to do anything. Configure your client for the HOTMAIL account with Verizon's outgoing server. It will automatically send via Verizon. You don't reveal your verizon.net address, you are just using their server to transmit.

Sending email using IMAP through SMTP Port 587

Hi,
I have been sending Mail Merged email to people in organizations that I am active in, using IMAP embedded in StarOffice 5.2 (on Windows 98 Second Edition). This worked fine until a few weeks ago when I received an error message stating that AOL, as part of their anti-spam efforts, was no longer accepting third-party emails on default port 25. All third-party email must now use port 587. I looked in the IMAP dialog and in the Tools -> Options dialog, but did not see any place to change the SMTP port. The AOL error message information page had instructions for changing the port in other applications (Outlook, Eudora, etc.), but not for StarOffice. So, I have some questions:
1.Is it possible to change the port in StarOffice 5.2?
2.If not, how does StarOffice 8 send Mail Merged email? Does it use IMAP, and if so, can the port be changed?
3.Also, I like the integrated configuration in StarOffice 5.2, where database fields can be directly accessed in the Insert -> Fields -> Other dialog. In looking at the Mail Merge section in "SO8_What's New.pdf", it appears that Mail Merge in StarOffice 8 is restricted to predefined fields. Could I still access fields from my existing databases?
These is a lot of questions, but right now I am blocked from sending Mail Merged emails which is imparing communications with volunteers who are running educational programs. I appreciate any and all help that anyone can provide.

Please try this out!!!!!!!!!
You can send emails using Outlook also. You can send email over Microsoft Exchange with this object (or another email server, using IMAP/POP).
Sub SendMailOutlook(aTo, Subject, TextBody, aFrom)
'Create an Outlook object
Dim Outlook 'As New Outlook.Application
Set Outlook = CreateObject("Outlook.Application")
'Create e new message
Dim Message 'As Outlook.MailItem
Set Message = Outlook.CreateItem(olMailItem)
With Message
'You can display the message To debug And see state
'.Display
.Subject = Subject
.Body = TextBody
'Set destination email address
.Recipients.Add (aTo)
'Set sender address If specified.
Const olOriginator = 0
If Len(aFrom) > 0 Then .Recipients.Add(aFrom).Type = olOriginator
'Send the message
.Send
End With
End Sub

Port 25 works fine for SSL/SMTP, but not port 587?

So after doing a rather painful migration to new hardware to support 10.5 from a previously working 10.4 config...
I got SSL working -- web service is fine, mail service is fine for all ports for POP and IMAP...but not port 587.
- It's open on my firewall
- There's no software firewall impeding it
- Trying to telnet to port 587 results in nothing
It's as if the server isn't even listening to the port...
And the odd part?
- Mac OS X desktop clients report they can't connect on 587. Changing the port to 25 and leaving everything else the same (auth type, username, password) -- suddenly it works...BUT
- The iPhone is configured for port 587 and works every time.
My guess it that iPhone auto falls back to port 25 if all else fails, I can't explain why it would work. Bigger question, I suspect something got munged in the migration...is it possible it needs to be told to listen on 587 as well?

I saw that site...it mentions adding port 587 specifically -- or commenting out "the appropriate lines of master.cf"
I assume that means to uncomment out the submission port in that file -- or would it be better to add 587 specifically?
Also, I never allow unauth SMTP (even inside my network) -- I would want to continue to impose that on the submission port and the normal port 25; how do I do this?
Thanks in advance for the help.

No Internet Access with Static IP and RVS 4000

I have an RVS 4000. I have several PC's to which I have assigned static IP addresses. I have recently upgraded most of the PC's to Win 7 (64) machines. I updated the firmware on the RVS4000 to 1.3.3.5 in conjunction with this. After such update (and actually before as well) I could not assign a static IP address to a PC and have access to the internet. It connects fine to my LAN, just no internet access. This is also affected on several other machines running Win XP and Win 2003 Server, so it's not just this computer.
I have:
     1. Shut down (powered off/unplugged) everything, router, DSL modem, switches, server, etc.
     2. As I said firmware is current.
     3. Yes, DNS servers and gateway, subnet, etc. are all correctly specified on the PC.
     4. Router is set for gateway mode.
     5. Set to only IPV4.
The only way it allows internet access is to use DHCP. I've even tried taking the IP address via DHCP and manually assigning the DNS servers and that works fine, but as soon as I assign a static IP internet access is immediately gone.
There must be something I'm missing, but I can't seem to find it.
Everything worked fine prior to the conversion of the Win 7 machines, i.e. I had several PC's with static IP's and no problems.
Any thoughts appreciated.

As an addendum, if I turn off the Firewall (internet access policy to disable) it will allow the static IP computer to have internet access. I have the DHCP range set to be .5 - .54 and am using a static ip outside this range. The Internet access policy is to restrict those PC's getting IP via DHCP.

Leopoard / Mail 3.1 and port 587

Hello,
I am starting with leopard and mail 3.1.
I have to change the port to go to port 587.
I canot find where to do it.
Help please.

Hello and thank you.
However, I knew how to do it in previous release of Mail.
As you said : there was a place called "réglages des serveurs" (tune the s"erveurs")
Mail, preferences,account, advanced ...... but the "reglages des serveurs " does not exist anymore
in Mail in the new release Mail 3.1
Therefore I dont know how to change (SMTP) PORT from 25 to 587.

I need to modify Postfix to listen to port 587

Mountain Lion Server OS X 10.8.4
Running Mail service with Postfix and Dovecot. In production with several mailboxes.
I need to modify Postfix to listen to port 587. I should be able to telnet to port 587, and finally send mail via 587.
587 already redirects to 25 via the firewall, but external devices need to visit the internal subnet without modifications to the mail app.
At this stage I just want to get it working with password authentication. SSL is a project for another day.
Here's my understanding of the OS X Postfix config:
/etc/services file:
Maps service names to port numbers. Port 25 is "smtp" and port 587 is "submission".
/etc/postfix/master.cf file:
Loads Postfix preferences. Service configurations for "smtp" and "submission" are listed at the top of the file. Each service configuration can be modified with parameters (-o variable_name_here=value_here).
I found many discussion boards with instructions for enabling 587. They suggest removing the comment syntax for the existing "submission" line:
# submission inet n - - n - smtpd
My server didn't have a comment, the line was already enabled:
submission inet n - - n - smtpd
I restarted services and 587 didn't work.
Then I tried a more direct approach:
587 inet n - - n - smtpd
This had no effect.
After each attempt to enable 587 I test with:
telnet 127.0.0.1 587
And I get: Connection Refused
I used the Server app and turned Mail off and on. This stops and starts Postfix.
I also used commands to restart Postfix:
postfix stop
postfix start
sudo postfix stop
sudo postfix start
postfix reload
sudo postfix reload
Nothing opens 587. Any ideas? Thanks in advance for your insights.

@Kraftwerk: You cannot change the TCP port used for SMTP. Well, technically, you can, but then no other mail servers on the Internet will find and communicate with your mail server. So... forget that.
The ISP controls the terms and conditions for the network connection, and particularly controls the network and network access. There's just no way 'round that either, as the ISP has the network position to implement port blocks and firewalls, and usually the contractual authority to allow or deny access.
With the proper (static) network connection and proper DNS, there is nothing to struggle with; this stuff works.
Which implies your ISP does not offer static connections, or there's an ISP error, or you're attempting to operate a mail server on a dynamic address. None of this works.
You might try mailhop service — if that's permitted within the limits of the terms of service — but it'll be easier and cheaper to host your mail elsewhere. Or to get a static IP address and proper public DNS, if your ISP offers that.
SMTP services are also tied to DNS, as well; other mail servers use DNS checks to detect rogue (spam) servers, and a mail server erroneously configured on a dynamic IP address will have mismatched DNS, and other mail servers will detect that and drop mail from and often to that mail server; that server is indistinguishable from a spam engine.
There's rather more the ISP can do as part of best-practices networking, too. TCP port 25 connections both inbound and outbound are usually spam engines operating on malware-infested, so it's common to block that traffic to reduce the volume of spam. Various ISPs will further blacklist dynamic IP address blocks, which means other SMTP servers using these blacklist services will ignore servers in these address ranges.
Get static IP. Or host elsewhere. Or (if permitted) mail hop.

SMTP does not start on port 587

I just activated IMAP and SMTP on an old G5 Server running the latest version of Leopard.
Everything, but for one thing, runs fine. IMAP works correctly from both the local network and any distant network I could try it. SMTP runs fine on the local network but only on port 25. Nothing is listening on port 587, or 465. Hence, SMTP does not work from a distant network.
The firewall is off, but even from the localhost, or any machine for that matter, telneting to port 587 does not get an answer :
telnet 127.0.0.1 587
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host
I did activate ssl for smtp in the Advance>Security tab. It uses the same selfsigned certificate as IMAP, which works fine. I can also tunnel in from a distant machine and SMTP will work.
I tried to uncomment the following four lines in master.cf
#smtps inet n - n - - smtpd
# -o smtpd_tls_wrappermode=yes
# -o smtpd_sasl_auth_enable=yes
# -o smtpd_client_restrictions=permit_sasl_authenticated,reject
but I only lost connection on port 25 and got nothing on port 587. This feels good, but I have no idea where to go from here.
Any one has any suggestion ?

I understand well that this is exactly SMTP, but just running on a different port, port 587, for submission, while port 25 is for relaying between server
That's pretty much it, except that port 587 should be configured to accept mail from authenticated users only (as determined by the line:
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
This enables authenticated users (e.g. users who have accounts on the server) to send mail through the server without restriction (e.g. they can be remote) while unauthenticated users (including remote mail servers sending mail to your domain) use the standard port 25
should I uncomment the lines for smtps in order to use SSL ?
smtps is still different from SMTP (25) and submission (587). Both SMTP and Submission can use SSL if you enable tls support - tls enables a connection to start off insecure/unencrypted and switch to encrypted if both the client and server acknowledge they support it. It's generally not recommended to require SSL/TLS unless you're sure every client that's going to use that service can support (and is configured to use) encryption.
smtps (which requires SSL) is now deprecated in favor of TLS (which allows the server to support both encrypted and unencrypted connections on the same port number).
