RE: Would double telnet work? [7:676]
I am not sure if the Netgear/Linksys does it but I know the Netopia routers do it!! http://www.netopia.com/equipment/routers/r9100/index.html Karl -Original Message- From: Fred Danson [mailto:[EMAIL PROTECTED]] Sent: Saturday, April 14, 2001 8:11 PM To: [EMAIL PROTECTED] Subject: Would double telnet work?

Re: Would double telnet work? [7:676]
I don't know that they do, but the Linksys does support port redirection. Just point the standard telnet port (23) at your inside router. Once on one inside router you can telnet around to others inside, or you can also point other ports from the outside to inside port 23. The biggest limitation that the Linksys has is that it can only handle one public address (I don't know if the NetGear or anything else can handle more). Not really a big deal unless you've got a bunch of gamers that want to be able to play against each other and the outside world, and they need to have the same outside public port mapped to play. Anyway, here is what you could do PublicPrivate 63.1.1.1 :23192.168.1.23 :23 63.1.1.1 :24192.168.1.24 :23 63.1.1.1 :25192.168.1.25 :23 63.1.1.1 :26192.168.1.26 :23 Of course, you might want to pick better ports, but if you don't care about housing services public services on the inside, it should work. My personal suggestion would be to set up an old 486 and run Linux and SSHv2 so that you can SSH in on port 22, and once on the Linux box on the inside, telnet to your routers. That way it's all encrypted and no chance of someone hijacking your lab. Plus, you can log all the connections to the Linux box and have a user list to control access. Of course, there is a little bit of a learning curve to get that configured, but it's not that bad with RH7 and a standard NIC. -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ ""Fred Danson"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Would double telnet work? [7:676]
The Linksys lets you do the following: incoming port (on wan interface) is redirected to inside ip (no port configurable) The incoming port can be further distinguished as udp/tcp/both 10 ports (or ranges of ports) that can be redirected to an inside ip address.
