Need help with Cisco port redirection / port triggering
Mods please move it to appropriate place if this is wrong place to post it.
Now coming to the question, we did a NAT of port 25 from internal server to external IP, works perfect. I want to open two ports on External IP i.e. 25 and 26 and NAT these ports to port 25 on Internal Server. We are using Cisco 7200 as Router and Cisco ASA as firewall I think this has to be done on firewall level, right? How would we accomplish this? Do we do Port redirection or port triggering or what? Help and pointers will be appreciative.
Also can someone tell me the rules of iptables to redirect port 26 traffic to port 25 and to allow all traffic.
Your help is appreciative.
