A tutorial on installing nginx on an NSLU2 for the purpose of reverse
proxying:
http://www.nslu2-linux.org/wiki/HowTo/ReverseProxy

which should largely be applicable to OpenWRT and other router platforms
that use optware packages.

The article also mentions Pound[1], which is strictly for reverse
proxying, and has been ported to OpenWRT.

See also this 2006-era thread that mentions Pound being ported:

Further up in the above thread is discussion of using the string module
for iptables to do deep packet inspection. The implementation details
aren't given.
