I tried to open port 25 via configmaker to allow SMTP Mail. It never saves the setting when I close.

How can I open port 25 Via telnet or hyper terminal.

Also does anyone know were you can a list of commands. (I am new to cisco)

Thanks

Here is the link which will help you configuring 800 series router

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/800/800swcfg/index.htm

Now to open smtp port i.e.static port translation of tcp port 25 of public ip address to internal email server ip address, here is the command

ip nat inside source static tcp 192.168.10.1 25 171.69.232.209 25

Where 192.168.10.1 is the ip of internal email server..public ip address for email server is 171.69.232.209
