Hello, I'm not sure if this is possible, but here is a diagram and explanation of what I would like to achieve.
(Inside) --- Cisco Router --- (Outside) ----[Public Internet]---- Host A | | ------ Host B
1) Host A connects to Cisco Router on port 5555
2) Cisco Router translates/forwards the request to Host B on port 7777
- Cisco Router is acting like a proxy/boarder gateway for Host A
- Host B only see Cisco Router connecting to it.
- Host A has no idea it's actually connecting to Host B
Any ideas would be appreciated.
