I am attempting to configure a Linux box (mandrake 10.1 - iptables 1.2.9) to redirect http, ftp, real, winmedia, quicktime, and nntp to a Netapp NetCache transparent caching proxy.
Here is my network layout:
~ Net ~ | ~ Linux router/fw ~ | - ------switch------- | | clients cache
Starting first with http, I have made use of fwmark and iproute2 to first mark traffic from our network to destination port 80 and then route that traffic, out the same interface it came in on, to the web cache. The problem I am trying to resolve is that the traffic that I am routing to the cache still has the destination port 80. I think this needs to be 3128 (The cache accepts connections on port 3128).
So, is it possible to rewrite the destination port in this scenario?
