Hello
here is my situation: the internet arrives via a fixed ip planet switch connected to a cisco ISR4451 router. The router is in turn connected to a Cisco ASA Firewall which connects to the rest of the LAN. Here's the question: i need to open bidirectional ports from external addresses eg. 192.192.192.192 UDP port 500 and 200.200.200.200 TCP port 4500 and direct them both to an internal server with ip eg. 10.100.100.100. Also I should open TCP port 22 from 200.200.200.200 to 10.100.100.100 and vice versa from 10.100.100.100 TCP port 443 to 192.192.192.192. with the commands: "ip nat inside source static udp 10.100.100.100 500 int ge0 / 0 500" i think i don't have the bidirectional connection, i have to use "ip nat inside destination or ip nat outside source"? Unfortunately at the moment I don't have the equipment to test but I need to prepare something working first. I'm getting confused ...
