Hello,,
I would like to extend the existing firewall configuration of a Cisco
1721 (IOS C1700 v. 12.3).For the section:
! ip access-list extended Firewall-In
I would like to add the following entries, to open up ports on an external IP (which is NATed to a LAN IP) for a second mail server:
permit tcp any host 6x.6x.2x.3 eq www permit tcp any host 6x.6x.2x.3 eq 443 permit tcp any host 6x.6x.2x.3 eq smtp permit tcp any host 6x.6x.2x.3 eq 995
After logging in with SSH to the router, I enter:
router# config -t
Could you let me know step-by-step, exactly what should I enter to add and save the new configuration, please?
As you can tell, I am not a Cisco guy, please bear with me.
Thank you very much for your kind help.
Regards, Nick
