I could see how rdr (which I understand to be the same as NAT?) could work, except it needs to be redirected to a program that then routes the traffic through the socks server? I have not been able to find such a program (and the above socks clients only act as a wrapper for other programs?). Perhaps a simple program that gets the redirected incoming traffic [like squid does] but then just connects to the destination server (with a socks wrapper doing the routing through the socks server)??? Or just a socks based solution? David
