For what you need to do, you need PPTP proxy which is available only in IPFilter 4.1. So you'd need to install the latest IPFilter (4.1.8 I think) and then just add this to ipnat.rules: map <external_if> <internal_net> -> 0/32 proxy port 1723 pptp/tcp -- Toomas Aas -------------------------------------------------------- |arvutivõrgu peaspetsialist | head specialist on computer networks| |Tartu Linnakantselei | Tartu City Office | ----------------------------------------------------- +372 736 1274help
