Thanks Narbik.. yeah kind of this solution but my issue is having auth-proxy
and this situation in one router. The authproxy steals the http session
before it even hits the nat. Applying nat goes just out.

Internet----R1-----fe0/1---R2-fe0/0-----|sw|----30 users

R2 is configured as a AUTH-PROXY doing authentication for 200 users.

The issue is if a server outside running on port 800 or non standard http
port, they can bypass the auth-proxy. Authproxy doesn't even ask them for
any authentication on non standard port.

So I was looking to redirect it on fe0/0 - anything that might work.

The conditions are fe0/0 must have auth-proxy we can't move it to fe0/1 and
user got to stay where they are!!
