I've been working on this for awhile now, but have bad no progress. I have a small regional Wifi network, the field units (private IP) all talk to a Cisco 7301 where I use ip nat to get them to go out the7301's public wan interface.
There is a company that I want to work with who can provide web content filtering, as well as access control. So they have a server at their location that I need to forward or redirect all my outbound port80 traffic to. This server at their location for arguments sake is listening on public IP 220.127.116.11 tcp port 21453.
The company has supported configs for PIX/ASA, but not for Cisco Layer3 switches or routers.
I've looked at nat, ssg, wccp, and cant really find anything that does this. My 7301 is running the latest 12.4 IOS Adv Enterprise Edition.
In addition to my ip nat inside and ip nat outside on the two interfaces, I have:
ip nat inside source list OutboundNat interface FastEthernet1/1 overload
Where Fe1/1 is my WAN link, and OutboundNat matches the private IPs to nat.
Is their a way on the 7301 to easily forward all outbound port 80 traffic to 18.104.22.168 port 21453? The followup to this is all other traffic (not port 80), should go out to the internet as normal.
Now I also have a 3750 Switch much higher in the network topology that actually hands off the traffic to my ISP, so I could also do something at that layer as well, especially if the 7301 load is too much. Right now with my current NAT, the 7301's are at 8% cpu load.
