Simple linux firewall for dedicated company network

Hi, we will setup basic firewall for small dedicated company network. Situation: all services for LAN users (email, proxy, dns, ntp) are situated in main company network, to which we connect using OpenVPN. So router acts as OpenVPN client, enabling tunneled incoming connections to this LAN from main company network. Created for Slackware. Take all this as fun example.
