I don't think that the udp stuff is necessary but I put it in there because Im to lazy to find out my natd.conf file #smtp redirect_port tcp 10.0.0.2:25 216.27.37.251:25 redirect_port udp 10.0.0.2:25 216.27.37.251:25 #pop3 redirect_port tcp 10.0.0.2:110 216.27.37.251:110 redirect_port udp 10.0.0.2:110 216.27.37.251:110 #imap redirect_port tcp 10.0.0.2:143 216.27.37.251:143 redirect_port udp 10.0.0.2:143 216.27.37.251:143 Chad Thunberg wrote: > > I am setting up a firewall and enabled natd but have an internal mail > server.
