Port Forwarding To Two Macs with Port 22 limitations

This is another port forwarding/port 22 issue and I've look around and not seen an answer to my specific problem. I work for a business that has an in-house ad system that runs on a Mac Mini. I have been accessing that Mac Mini remotely because we set up port forwarding through the Linksys rounter that is at the business using port 22. This is the only port that works for this connection to the mini and the software.
We are now adding a second Mac Mini to send the ads to a different set of monitors. I can't set up port forward to the new mini on the same port so I don't know how to connect to this mini remotely. Is there a way to get into the first mini through port 22 and then somehow communite to the second one through the first? Is there another way to do port forwarding...or have the linksys router switch from one mini to the other when a request comes in? There will only be one remote computer trying to reach either Mac Mini so there will never be simultaneous traffic coming in. Any help would be appreciated!
The linksys router is critical to the business becasue a host of other devices are forwarded though it as well.
Thank you.

I'm now wondering if port forwarding to two identical devices actually works in principle with HH4? Has anyone else done this?
If in the Home Hub 4 A you go to
Advanced Settings
Firewall
Port Fowarding
Manage Games and Applications
You get the following statement:
"Each game or application can be assigned to only one device on your home network"
I would think that the only way round your problem is to have each Camera running a different application or the same application with a different name.
Does the remote browser app need to know the application name or just the device name ?
If you think about how Port Forwarding needs to function you need a way whereby the remote user needs to be able to tell the Hub what Camera to talk to.

Port Forwarding for Two Macs, one Airport Extreme and one Dynalink RTA1320

I had previously set up PortForwarding for some of my Applications on my iMac with an Ethernet connected Dynalink RTA1320 Modem by assigning myself a Static IP in the iMac`s Network Preferences.
All had been good, green smilies on Azureus when D/Ling bitorrents, Skype, WoW and Limewire all running fine.
I`ve now just recently purchased the latest Airport Extreme and 17" MacBook Pro.
Setting up a Wireless Network for the two Macs to access the internet was a breeze and both computers run fine online simultaneously.
I manually set the Ports on the MBP Applications: Skype, Azureus and Limewire to match the Ports I`d previously PortForwarded the RTA1320 to.
However, on the new MBP, Skype, Azureus and Limewire don`t seem to run too well.
I get yellow smilies on Azureus and a "Port Appears Closed" message on the NAT Test and my Skype Contacts are leaving me messages saying I always appear "off-line".
The iMac Apps still work flawlessly.
I`m guessing the problem is something to do with two Macs on a Wireless Network with one Static IP Address or what am I doing wrong?

...Wow, 36 views and no replies with helpful advice!
Just like my other question about a month`s data disappearing in iCal, nobody has offered any helpful advice!

Port Forwarding to two computers.

I want to open ports for an application that I use on two different computers. I have been able to forward the port to on (static) ip and everything works fine. But when I use the application on another computer the port is closed. On my previous router I could say port map to 192.168.0.* and all computers would have the port open, and the app would be fine on either computer. The AEBS does nor recognize the *.
When I set up the same port forward to two different ip addresses with the same ports open I get an error that the port mapping already exists. Is there a way just to have the port open for any computer on the network?
How would I allow incoming traffic to a specific port on either computer? Normally the application is only used on one computer at a time.

Can connect two Macs with USB2 cable?

Can connect two Macs with USB2 cable?

You can connect two Macs with an ethernet wire, or conect two Macs using Firewire if one is placed in target disk mode, but that is it.

Can I connect two macs with thunder bolt ?

can i connect two macs with thunderbolt like I do with firewire and IP? I don't want to transfer files by using the control "T" at startup . I want use VNC to control one mac from the other and use thunderbolt vs ethernet.
thanks for any help

You can connect the two. Whether you can use VNC, I have no idea.

Time Capsule: Port Forwarding Issue and DHCP with Westell 6100g Modem

Ok two issues as of right now, but more down the road i think... Anyways, number one, i would like to be able to backup my computer using time machine and my time capsule.. Right now it works properly when inside the local network, was wondering if there was a way to backup when outside the network... i travel a lot and always have my macbook pro with me.. Also, i have a USB hard drive connected to the usb port on back of time capsule but its not showing up anywhere... is that only for printers??? that's not such a big deal, but would be nice to have access to that hard drive from multiple computers... OK so part two of my issues is, i have a WESTELL 6100g modem for DSL verizon service, which is crappy, but that's besides the point, it is a modem/router, so i have the time capsule connected directly to that westell.. the westell only has one Ethernet port, so that's wired to time capsule and then my computers are connected wirelessly and wired through the capsule. It seems that the westell is distributing the IP's and is controlling the port forwarding and what not.. I have tried a few things to give control to the time capsule but that didnt work.. i followed these directions on the web page http://www.dslreports.com/faq/vz/4._Hardware#13600 but it didnt work properly, i couldn't log onto the web at all.. Maybe im doing something wrong.... Anyways, what i really want to do is control everything that the westell is controlling right now with the time capsule... i want to give out IP's and also control port forwarding with the capsule.. Any way of getting that accomplished would be AWESOME... I'm somewhat intelligent when it comes to computers so i should understand everything you are talking about... please help!!!

If you have Back to my Mac (available online service from Apple's MobileMe), then you can perform the following actions with your Time Capsule remotely,
1. Remote disk access to both the Time Capsule disk and a compatible disk connected via the Time Capsule's USB ports.
2. Remote configuration.
Also, i have a USB hard drive connected to the usb port on back of time capsule but its not showing up anywhere... is that only for printers???
Printer, hub, or compatible disk.
http://support.apple.com/kb/HT2421
Anyway, it could be a setup issue for you, assuming you have Back to my Mac (MobileMe) then the procedure for Time Capsule services is shown in the following Apple support kb

and for USB disk please see the following Apple support kb

Port forwarding using Transmission & Mac Pro

I do a lot of film editing for various clients and make my work available to a host of individuals via torrents using Transmission 2.84. Some complain my client (Transmission) is not connectable and they are not able to directly connect.
To fix this problem I'm told I need to perform port forwarding but I am lost as how to do so.
I'm on a Mac Pro with built-in Airport Extreme using Yosemite. Some advice has been to open System prefs > Security >> Firewall and make sure "Set access for specific services and applications" is selected then click the + button and select Transmission from my Applications folder then make sure the pull down menus is set to "Allow incoming connections".
The problem here is that I find nothing under Firewall offering the "Set access...", just the option to turn on/off Firewall. I turned it off but still no success.
How exactly (step by step would be helpful) do I set up port forwarding using the above machine and torrent application?

I do have exactly 1 computer. The computer came with an internal AirPort Extreme card. The machine is sharing a self-assigned IP address to provide an internal WiFi connection with an HP Printer.
Inserting the IP address takes me to a Comcast Business Gateway screen asking for User Name and Password.
Looking up Name/Password for AirPort Extreme models I get this:
Model
Default Username
Default Password
AirPort Base Station (Graphite) 2
(none)
public
Airport Base Station (Dual Ethernet) 2
n/a
password
Airport Extreme Base Station 2
n/a
admin
airport5 1.0.09
root
admin
AirPortExtreme
NONE
NONE
I also tried the suggested Comcast and Comcast Home Networking router name/pwd. I do not find a name/pwd for a Comcast business router.
All are rebuffed as incorrect.
Here is AirPort Extreme info:
Card Type:
AirPort Extreme (0x14E4, 0x88)
Firmware Version:
Broadcom BCM43xx 1.0 (5.10.131.36.16)
MAC Address:
00:1c:b3:ff:5a:a8
Locale:
FCC
Country Code:
X0
Supported PHY Modes:
802.11 a/b/g/n
Supported Channels:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165
Status:
Connected
Am I just using the AirPort Extreme card to provide the self-assigned IP address for WiFi and the actual internet connection is being handled by the business router provided by Comcast?
How do I overcome this hurdle?

How to set Port Forwarding for video chat with AIM user?

I'm trying to setup video chat between my Mac in the US (with iChat 3.1) and my friend's PC in Japan (with AIM). I need to know what ports needs to be forwarded on my friend's router, and/or on my router.
Right now, when I attempt video chat with my friend (in Japan) at my home network, the invitation only works one way (me -> friend). And when I try to do it at work, it doesn't work at all.
Help appreciated,

Hi,
I am also having a similar problem that perhaps others can help with.
I'm using an iMac G5 with iChat here in the States, and am trying to connect to my parents' PC running AIM 5.5 on Windows XP sp2. To complicate matters, my parents have a Belkin wireless modem/router that they use to connect to the Internet.
Currently, I can text chat with my parents, and send files to them via iChat. However, whenever I try to initiate a video chat, I get an error saying that "Phil Waymouth" (i.e. my computer) isn't responding.
This is where we are at the moment:
- Internal firewall on my G5 is turned off. I can port scan login.oscar.aol.com fine for both TCP and UDP.
- XP firewall on my parent's computer is on, but has UPnP Framework (ports TCP 2869 and UDP 1900) set up as an exception.
- I've gone through the stages on http://portforward.com to set up Port Forwarding on my parents' Belkin router. In addition, we've enable UPnP on the router and restarted it. However, if we use www.myip.dk to get the IP address of one of their computers, and attempt to port scan it, it fails.
It feels like it's still either their router, or some ISP issue that's the problem?
I apologise for re-hashing the same problem, but perhaps someone here will have a lightbulb moment!
Any help is much appreciated,
Phil

Port forwarding between two servers from Same subnet

Hi,
We have a Cisco ASA 5520 Version 8.4(3). There exists a site to site VPN tunnel between us and a client and the client sends us the data to our local host/server 10.x.x.20 on port 52944. So 10.x.x.20 gets data on port 52944. We want to forward this data to a test server 10.x.x.21( same subnet IP) on port 52945. so basically I want to forward traffic from 10.x.x.20:52944 to 10.x.x.21:52945.
Is this possible. I am a new bee to the networking and still learning. Excuse me if this sounds silly.
I know we can add one more ACL in the VPN tunnel and add this test server IP in the ACL. but, then I have to ask the clinet to change their ACL too. I dont want to do this. So I want to wrok around it. Any help or suggestions is much appreciated.
Thanks in advance :)
This is my first ticket in the support community.

VMs have nothing to do with it, as long as there's network communication between the servers.
As I said, there must be a service or application listening on that port for it to respond. For example, try this:
C:\> telnet
When the telnet prompt opens, type in:
open mail.messaging.microsoft.com 25
If it works, you should see this:
220 CH1EHSMHS035.bigfish.com Microsoft ESMTP MAIL Service ready at Thu, 7 Feb 2013 00:57:33 +0000
That means that Microsoft's mail servers are LISTENING on port 25 and it responded. And note, telnetting to port 25 is a non-default telnet port, because port 23 is the default telnet port. When you type in a space and then a port number, you're telling
the telnet client to use that port.
That is the SAME THING if some sort of application or service is listening on port 8444 on that other server you're trying to telnet to. If there is no app or service listening, it will just time out.
And no, installing the TELNET service on that sercver will NOT answer to any port other than 23. The telnet service by default, uses TCP 23, unless you specify otherwise.
So once again, what service or app on that server is supposed to be listening on 8444?

Airport Extreme Simultaneous Dual-Band port forwarding broken if only TCP ports with firmware 7.6.1

When configuring my Airport Extreme Simultaneous Dual-Band router, port forwarding is broken if you only specify TCP ports to forward. This is with firmware 7.6.1. What happens is that after you hit the Update button, when the router comes back and you open the port forwarding entry, the IP is still there but the port numbers are missing.
I tried all different port numbers and ranges and nothing would stick if i only specified TCP ports. If i added UDP ports with the TCP ports then it would save them. And if you add a new entry with only UDP it saves them too.
Now this is with adding a new port forwarding. I already have existing ports being forwarded that only have TCP. They are still working. I believe i added them with a previous version of the firmware.
Any one else see this issue? Any ideas?
Maybe i should perform a hard reset and reload a saved config.
Peace,
Dan

I haven't seen the issue but you could just downgrade to an earlier firmware:

WRT160Nv2-Problem with Single Port forward to multiple servers with same internal port numbers.

On my network I have 3 systems that I've set up as RDP hosts. And need to get to all three of them externally. So I'm trying to do the following single port forwarding.
RDP 1   Forward 4000 to port 3389 for 192.168.1.11
RDP 2   Forward 4001 to port 3389 for 192.168.1.12
RDP 3   Forward 4002 to port 3389 for 192.168.1.14
When I hit "Save Changes" I get the error "Port range already exists". So it's good that it won't let me overlap ports generally, but at the same time, I'm trying to send them to different IP address. There should be no overlap in this case. Please advise
I'm trying this on the WRT160Nv2 with firmware 2.0.02, which I had just bought this weekend.

kevj,
Thanks for your suggestion. I have now upgraded the firmware to 2.0.03 build 7. But I am still seeing the error message
As I mentioned previously, I'm trying to single port forward to multiple machines in the following way:
Machine 1:   Forward 4000 to port 3389 for 192.168.1.11
Machine 2:   Forward 4001 to port 3389 for 192.168.1.12
Machine 3:   Forward 4002 to port 3389 for 192.168.1.14
The error appears to be generated by the fact that 3389 is selected for multiple external port numbers, but the same internal port number. The router I believe isn't taking into account that the similar internal port numbers aren't taking into account the different internal ip address I'm trying to send this to.
This would be a standard sort of practice for running a live HTTP server on one machine, and a new beta HTTP server behind the router on a secondary machine on the same internal port, but different external port numbers for test purposes from the outside.
Please advise
Thank you.

Connecting two macs with afp

Both a friend and I got brand new Mac Book Pros for college but he is going to a different college so were trying to get it set up so that we can transfer files between each other and access each other's computers. I started toying with afp but have been unable to get it to work even after checking my sharing settings. On another point I have thought about creating a VPN but have soon come too realize that that could be more complicated to setup and use. Can anyone see a problem, a I missing something?

Hi RustyBoltz,
Welcome to the forum.
You'll both need to forward (map) port 548 in your respective routers to the internal IP of your respective Macs. Port 548 is the Apple Filing Protcol (AFP) over TCP port. Forwarding it to a computer's internal IP enables a remote user to simply click on the Go menu in the Finder menubar, select Connect to Server..., enter the ISP assigned IP address (if not known can be found by going to www.whatismyip.com) and then, after entering their username/password be able to access the files on the remote Mac and upload/download files.
Alternatively, you can use an online server like .Mac to upload files to a Public folder that can be accessed by both of you.

How to get SMS forwarding on two macs

I have two macs and want SMS forwarding on both of them. But it looks like you can only have it on one at a time. They always switch names and sometimes both don't work when I am trying to hook them up. How do I get them both to send and receive SMS?

Thank you both, I've found some third party sharing software for example SugarSync - But might just go with local network - home folder.

Sharing between two macs with one user account?

Is it possible to connect two macs to share documents and music if they are both logged into the same user account?
I recently bought a Mac Mini and when setting it up, I transferred everything from my Macbook Pro to it, including my user profile which I now also use on the Mini.
Since setting up the Mini, I've been using both machines so the content on both is no longer identical. There have been occassions where I have wanted to transfer something from the MBP to the Mini or vice-versa over wi-fi and have encountered problems. I suspect this is because I am using the same user account and they get confused.
I don't need the two macs to be identical in their content, however there are times when I want to share or quickly transfer music, documents or Garageband files from one to another. Would I be better off setting up different profiles for the Mini and the MBP to achieve this? Is there a better way to do what I'm trying to do?

There have been occassions where I have wanted to transfer something from the MBP to the Mini or vice-versa over wi-fi and have encountered problems. I suspect this is because I am using the same user account and they get confused.
Could you please explain, what kind of problems exactly you encountered? Error messages? Corrupted files? And why do you think the problem is caused by the same user profiles?
Like markwmsn I have no problem with sharing using the same account name on all my macs. Only since upgrading to Mt. Lion I usually use AirDrop to send single files. That saves the trouble to copy the files to a public folder.
Do both your macs support Air Drop?
