Thanks for such quick replies! >>PRIV_PROXY_IP=192.168.0.2 >>PUB_PROXY_IP=a.b.c.d >>IPT=iptables >> >>$IPT -t nat -I POSTROUTING -s $PRIV_PROXY_IP -o eth0 -j SNAT --to >>$PUB_PROXY_IP I just tried this solution but now the proxy can't access the DNS servers. I think I know what the problem is. I'll try both suggestions tomorrow morning. Right now I have a bunch of angry people calling my office because they can't connect to the proxy server :) Later.
