Configuring Cisco 1841.

Hi,

I have 1841 router which is to be configured Step by step with NAT, VPN, ACL,

I have configure it basic setup (find the configs in attached code)

But before going further to configure NAT VPN ACL, etc....

1) I noticed that i am not able to telnet into my router from outside.... rather inside from my PC i can login via telnet,

2) Could 1841 router be a VPN Server...if yes...pls share the commands to config it..& how can i test it.

Kindly advice at earliest possible,

thanks in advance...

-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for  one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to
use.
