hi, sometime last month someone here offered to help me sort out getting two SER servers working behind two Linux firewalls doing NAT with iptables. As i said then i was having email problems but that's all fixed now so if that person, or anyone else can help, please say. cheers, and i hope i can get this working :) -- Mat Harris ( ) ASCII Ribbon Campaign mat.harris(a)genestate.com X against HTML on email Network/Systems Administrator / \ and Usenet posts
