I have a Telnet BBS setup which i used to run about 4 years ago.
I have decided to put it online again, but since that time i had changed my ADSL modem to another model with built in router.
Basically the problem is that when i try and connect via telnet to my BBS, instead of my telnet server answering, my adsl modem/router answers with its own built in telnet server.
Any ideas? I have tried setting port forwarding
EDIT: The model of the ADSL Modem/Router is Thompson TG585V7

From where are you testing the connection? The port forwarding probably only works when you connect from "the internet". If you try connecting to your outside internet address from inside then possibly the port forwarding does not work as expected (eg. does not forward you to the inside server but instead terminates the session locally - ont the router).
Soooo, test from the outside first. Or PM me the IP address and I'll test it for you from NL...

Telnet is way obscure to use anyway - why not use an alternative port if everything else fails?

Either way it is port forwarding and still needs to be configured. Is there a place where you can turn off the built in telnet server on the router? You could always put the router in "bridge mode" to where it acts only as a modem and then use another router for port forwarding.

? Telnet is almost as basic as it gets.
@dougal
You should disable telnet on your router, regardless. Why anyone would that accessible from the outside world (apart from your ISP, which probably wants to be able to change things) is beyond me.
As suggested, use a different port. You could be cheeky and use 31337, retro and use 43164, or whatever you want. Just pick something higher than 1023 and avoid fixed ports used by well-known file sharing protocols as you're less likely to experience blocking or filtering by your ISP.
Then, run 'telnet ' or configure your telnet client accordingly to connect.

Telnet is probably only enabled on the "inside" network... The Thomson modem/router is not that bad ;-) And if I understood correctly, he is trying to get his BBS up and running... if dougal hides it too well there will be no users...

Sure is (probably the oldest 'high-level' protocol still in use - somewhat that is) - it's so basic, most people won't be able to use it nowadays. Most probably panick if they click on a link and a black box appears with text in it...

It must be a port forwarding setting i am doing wrong. Because with another router (@ work) it worked perfectly.
Thing is the Thompson is a good router but its settings etc.. are a bas**rd to work out.

Ok, I updated my router/modem.
What i realize now is the following:
If i enable Port forward, when i try and connect it no longer goes into the router's own telnet server, but instead it just refuses to connect.
I tried a website which tests port forwarding and it says my Port 23 is CLOSED.
Question time:
Does that ^^ mean that it is CLOSED from the router or the computer?
I have a Mac and my BBS is running in Windows7 in Parallells.
Could Snow Leopard be keeping the telnet CLOSED?
Is it worth my trying to run the BBS from my old WindowsXP laptop ?

Telnet is closed by default on the Mac. You may need to turn it on.

You may want to create an automater script to turn it on and off. When you take the BBS down for some reason you can shut telnet down for security.

My guess is that you are trying to get the outside IP to your VM in Parralels, so no need to enable telnet on your Mac. Check how your Parralels VM's network is configured... You probably need to set it to "Bridged" instead of "NAT". If it's bridged it should get an IP address from your routers DHCP (if you're using that). If port-forwarding is setup correctly on your modem/router it should connect from the outside.
-
If your Mac's got a telnet daemon running on port 23 that port is busy anyway. Configure your BBS to use e.g. port 8023 and set your router to forward TCP port 23 to port 8023 on the Mac's IP. Take care you open port 8023 on your local firewall (if present) as well.
-
It is probably a good idea to troubleshoot these disparate issues independently from one another.
If your goal is to run a telnet BBS on an emulator, you are going to need the following.
- Port forwarding from the public IP to the IP of the computer that is hosting the Amiga Emulator.
- Most Amiga BBS software requires a "device" to function like "telnetd.device". Newer versions of WinUAE offer ethernet card emulation which you will need to enable and configure with an Amiga TCP/IP stack to allow this device to work.
- You will need a program such as WinPcap to send the TCP/IP traffic from the host OS over to the Amiga OS through windows.
- I don't think EUA or the the Mac OS have the necessary combination of magic to allow you to run bbs under emulation but I would be more than happy to be proven wrong on this assumption.
- Trying to get this working on parallels is going to add another layer of complexity (as previously mentioned) because of the way IP traffic is handled through parallels (Bridge or NAT.) In short, you are making this several orders of magnitude more difficult than it already is by doing this. If you have boot camp, get it working from there instead / first.
So the first thing you should be concerned with is getting port 23 to pass from your public IP to an IP address on your network. Try turning on telnet on your Mac and see if you can get a response from the internet.

l noticed on my router modem nz made brand that had setting reguarding telent and port fprwarding even had setting for selecting one the dyd.org havent tryed it as forgoten password to log in doh am trying to get my cnet bbs up and running but first got work out

see roadshow for 68k might be out soon so might help with my amiga 1200
as with miami dx online with one irc program ran out ram aghhhh

Ok, I have managed to iron out the major problems and the BBS is now online on trial.
I am starting another thread to sort out minor problems.
