Can't telnet to AS from WAN!

imsisko

Hi folks!

I have this issue that I can telnet to my Access Server from the LAN but not from WAN. I thought it's router/firewall misconfiguration but when I assign the same port forwarding rule to another device(my pc) it works fine. Here is the config of the AS:

AS#sh run

end

AS#

My default gateway is 10.0.0.1/27
Any thoughts?

Thanks!

Router#conf t
Router(config)#line vty 0 4
Router(config-line)#password cisco
Router(config-line)#login

Ttelnet access requires a password and the login command to allow telnet logins.

Edit: You can also use the "no login" command, which contrary to what it sounds like it would do, allows telnet login without needing a password.

Yes I've tried to add that command as well but the router didn't accept it.

#Incomplete command

The only format that worked was the

#login authentication default

The weird thing is that I can telnet into the router from a local computer (username and password required) but not from the outside network.
I'll again *later when I go home.*

Thanks!

You need to use the ip route command for a static default route not the ip default-gateway.

Thanks networker! I did some searching and it finally makes sense why it worked with a switch but not with the router!!
