Reverse Port Redirection with ASA5505
Hello Community.
We have a singe IP Address in the Internet and want to forward SMTP traffic that hits our ASA Outside Interace to the internal Mailserver.
And we like to forward Http Traffic to our Webserver.
Example.
212.23.23.23 Port 25 -> 192.168.1.100 Port 25
212.23.23.23 Port 80 -> 192 168.1.200 Port 80
How do i acomplish that. Which NAT rules do in need?
Thanks Patrick
Hi,
Glad to help
We do need a NAT configuration usually for both VPN Client and Site to Site VPN to function correctly. I guess the only exception is when a single ASA is ONLY used for VPN. Then you can actually have the ASA without ANY NAT configurations at all. But this doesnt apply to your situation.
You basically already listed the type of NAT configurations you need already.
Lets say we have a site with ASA firewall and that ASA has one Site to Site VPN and one VPN client connection configured.
The local site is 10.10.10.0/24
The remote site is 10.10.20.0/24
The VPN Pool is 10.10.100.0/24
With the above information if we wanted to make it so that both the local site and remote site and the local site and vpn pool could communicate using their original IP address, then we would configure the NAT in the following way
object network LAN
subnet 10.10.10.0 255.255.255.0
object network REMOTE-LAN
subnet 10.10.20.0 255.255.255.0
object network VPN-POOL
subnet 10.10.100.0 255.255.255.0
nat (inside,outside) source static LAN LAN destination static REMOTE-LAN REMOTE-LAN
nat (inside,outside) source static LAN LAN destination static VPN-POOL VPN-POOL
The same logic would apply if you were to configure more Site to Site VPNs or VPN Client connections on the local firewall.
Hope this helps

MorganMorgan,
Your config is perfectly fin. You have your PAT static and opened the ACL for that port
access-list outside permit tcp any interface outside eq 1042access-lis outside deny ip any anystatic (inside,outside) tcp interface 1042 192.168.1.60 1042 netmask 255.255.255.255 0 0access-group outside in interface outside
The issue is somewhere else. When you try to connect check the conn through the PIX "sh conn | i 192.168.1.60", and you should see the conn.Check if the camera needs more ports to open and what the PIX logs show.
I hope it helps.

Virtual Hosts & Port Redirections
Hi guys,
In 10.6 i used to be able to setin the Server Admin GUI settings for the web service. This included Virtual Hosts & Port Redirections. How do i go about doing this on 10.7?
For example, I need myserver.mycompany.com:80 to redirect to myserver.mycompany.com:8088 & mygreatsite.company.com:80 to redirect to mygreatsite.company.com:9006.
Both of which are hosted on myserver.mycompany.com.
Links apprecaited.. i'm guessing i'm in for an Apache lesson?I hope that article helps you, maybe you can figure it out and post back for the rest of us!
I haven't actually read it yet, I just saved it to my Pinboard page for later, because I know eventually I will have to deal with vhosts in Lion. -
Confused asa 5520 port redirect
HI
The network was simple like thie
lan-------------(gi 1)--asa5520--(gi 0)--------------wan
lan subnet is : 192.168.0.0/24
wan: only one ip address 1.1.1.1
The reqire was that: allow all lan hosts access to the internet .
there is a www server (192.168.1.10) in lan. Need it to serve for internet.
I config the asa like this:
interface gi 0
nameif outside
ip add 1.1.1.1 255.255.255.252
interface gi 1
nameif inside
ip add 192.168.1.1
object network lan_hosts
subnet 192.168.1.0 255.255.255.0
nat (inside,outside) after-auto dynamic source interface
object networkd www_host
host 192.168.1.10
nat (inside,outside) static interface service tcp http http
after that, i access the http://1.1.1.1 from internet. BUT the port redirection wasn't work.
what's wrong .
can someone help me!
tks.Hi,
Although I can't see anything wrong with the actual NAT configurations I would suggest the following for them
Default PAT for LAN
object-group network DEFAULT-PAT-LAN-SOURCE
network-object 192.168.1.0 255.255.255.0
nat (any,outside) after-auto source dynamic DEFAULT-PAT-LAN-SOURCE interface
Port Forward configurations you can leave them as is.
Have you opened the traffic with ACL also?
For example
access-list OUTSIDE-IN Remark Allow HTTP for Server
access-list OUTSIDE-IN permit tcp any object www_host eq www
access-group OUTSIDE-IN in interface outside
Please rate if you have found the information helpfull. Ask more questions if needed.

I need to communicate with a datasocket through a firewall where I can open only 1 port. This article: http://digital.ni.com/public.nsf/websearch/FCF8A1464BD2F6D686256B59007C9A6F?opendocument&Submitted&&node=133020_US explains that datasocket client use, a random port in interval: 1024-65536. Do you know if exists a windows tool for port redirection (or other tricks...)?
Thank you,
paolo.I haven't tried this, but the first thing that comes to mind is specifing the port after the datasocket address. Something like this...
dstp://192.192.0.1/getdata:1024
You use this same format for URLs when you need to use a specific port.

Port redirection in Border Manger 3.7
Hi
I configured a windows 2000 based VPN server inside my lan .My lan is
protected with border manger 3.7.I configured my perimeter router to
forward all packets to the border manager.Now I have to redirect all VPN
calls(PPTP tunnel,port 1723) to my internal vpn server.I tested the vpn
connectivity by bypassing the border manager and it worked fine.How can I
do the port redirection in Border Manger?

Do BM provide port redirection ,if so how can I do it?

RV180W - problems on rules and port redirections
Hello,
I installed a RV180W router a month ago.
Our production server has to retreive informations on a remote server so I set up the rules and port redirections accordingly on the firewall.
I noticed that some times the rules didn't work anymore and I had to reboot the RV to fix it.
The rules are still active on the router's admin panel as well as the services and the port redirection. The last firmware is installed.
Does anyone experienced the same problem and found a fix?
Thanks in advance,
Best regardsI hate to say it, but there are issues like this with the rv series. Have you replace the router with another one? That's the first thing I would try since you can probably exchange it easily right now.

Using Oracle 9i on Linux with remote client connection, how does one force port redirection? Specifically we have the listener on port 1521 and want the server to respond to the client on a different port.
Thanks,

like
listner

X1 and USB Port Replicator with digital video - hangs system
Hi
with the X1 to help with docking it everyday at the office I have a USB Port replicator with digital video. I am not using the digital video but the USB ports, head phone and mics plus ethernet.
When I plug it in it detects it OK, I then installed the software. But after reboot it looks to stall when logging into windows, screen flickers back and forth and locks up the operating system. I unlplug it and reboot and window is working fine.
Note as I mentioned I am not using the digital output but instead using an external monitor via the display port on the back of the laptop.
Also its is very slow to boot (Lenovo bios splash screen is there for about a minute)
I have gone into the bios and turned off all other bootable devices just leaving the laptops hard drive.
As a work around I have removed the software and I am getting the basic functionality of the port replicator, but not the ethernet.
I have run the update manager but does not appear to show a need to update the drivers.
Model X1 (1293-CTO)
Windows 7Hi, I have this same exact problem.
Video (anything from youtube to downloaded shows, movies) will freeze for 5-7 seconds at a time. The sound continues to play while the video is 'frozen', and the video resumes after that.
It will happen on its own, with no bumping, but it is more prone to happen if I do something like increase the volume within the media player.
Any suggestions are much appreciated! -
Reversing a document with MR8M diff value in GR/IR
When reversing a document with MR8M, differrent amount is posted to GR/IR account and PPV account
Actual Transaction
Vendor 123 = 100

After Reversal:
Vendor 123 = -100
GR/IR account = 78
PPV account = 22
Please let me know what could be the reason?
Edited by: Rickyy on Apr 27, 2011 9:33 PMThis sap note explains exactly my problem, but now how do I clear GR/IR account?
GRIR Account PPV account

Is 'Thunder port' compatible with 'mini port' cords/divices?
I am attempting to use my Imac 27" as a display for my xbox 360. So as instructed by "Apple chat" I purchased a KANEX XD connector for $140 and now it is not woking because of the Thunder port. Then I seeked assistance once more from "Apple chat" to purchase the Thunderbolt cord and by replacing the mini port cord with the thunder port cord my divices "should" work. I need to know if tis will work before purchase. I have beed instructed to purchase 3 items just for this one issue and 2 out of 3 have not worked and now I am -$160.00. Will purchasing this new cord solve my problem?
But before the transition from mini to thunder, the mini display port could be attached to a KANEX XD and then to an XBOX 360 using the previous 27" iMAC then as a monitor screen for game play...
So I already found out the NEW 27" iMAC can only receive video/audio from another thunderbolt port using the thunderbolt cord to a thunderbolt port again. Does this mean I am going to have to return all the purchased items and wait for a connector to become available to connect 360 to Thunderbolt? -

My firewire port works with ext hd but not with audio interface
2010 Imac 21.5 running 10.8.5. My firewire port works with ext hd but not with audio interface. The local authorized Apple tech said that I need a new motherboard, but my firewire ext drive works perfectly. I don't understand. Thanks.
You must go to the website of the audio interface manufacturer and look for, download and install updated drivers for the audio device you are using.
This is not, neccessarily, an Apple issue. -
Reversal of delivery with handling unit management/HU #
Hello all,
I would like to know whether the delivery with handling unit management is reversed using LTOG. if it is reversed using LTOG in which storage type would the stock be posted back and would the packaging material of the handling unit be the same when the delivery is canceled and posted back in stock. pl. advise.
Thanks,
MaxxHi Ramana,
Thanks for your reply.
in your answer you have said it is not possible to reverse a TO with HU.
But is it possible to reverse a delivery where the HUs are created only after packing the delivery items. if it is possible then how the packaging materials in the handling unit that are reversed are handled and where are the stocks that are returned after the delivery is cancelled is posted - i would like to know the standard sap storage type in which the stocks are posted once the delivery is cancelled or reversed.
Thanks,
Maxx -
