Port triggering on Cisco IOS..?

How can I implement port triggering on Cisco? Any ideas?

I thought to use route-maps, but I see that "ip nat inside source static .."

have no option route-map :(

Any other ideas?

Re: Port triggering on Cisco IOS..?

You are in the right track.

It will be:

ip nat inside source static [inside ip] [port] [outside ip or interface] [port]extendable

for instance to forward port 80

ip nat inside source static 192.168.1.1 80 66.125.55.254 80 extendable

Please rate helpful posts.

Thanks

Thanks, Edison, but as I understand - it is a simple port forwarding..? and I need port "triggering" (I mean: http://en.wikipedia.org/wiki/Port_triggering)

Some kind of temporary port-forward

access-list 101 permit tcp 192.168.1.0 0.0.0.255 eq 80 any eq 80

route-map portmap permit 10

match ip address 101

ip nat inside source route-map portmap interface [outside interface] overload
