Was asked about this and unsure - but here is the situation
I have a cisco router with 1 ISP (public ip 188.8.131.52) and 1 LAN interface (192.168.100.1). I have port forwarding setup so that port 8080 on 184.108.40.206 will go to a certain IP on the inside (192.168.100.5). All users are PAT'ed to the 220.127.116.11 address with the overload command for outbound connections.
What I need to happen is this - when a user inside (192.168.100.x) tried to access 18.104.22.168:8080 the router will need to nat him back inside and allow him to access that server
I accomplish this on an ASA by using the nat(inside,inside) command but unsure how to do this on a router or even what search parameters to use in google/cisco tech pages
any thoughts or help?
