Sorry about that. I'll be more specific. I work for a small ISP, and we are selling residential and business wireless service. Thus far, using iptables NAT, we've had no problems. It works well and permits MSN Messenger and the like to work. For those people who want a public IP, I simply do forwarding, and this works very well. However, we've had some inquiries about a few businesses who want actual subnets (for mail servers, web servers, or whatever). The problem with NAT is that I can't guarantee there will be a helper for every protocol. What I was wondering was whether I could allocate a subnet and get it across the private (NAT) network to their router. I have my doubts as to whether this is possible, but not being an expert I thought I'd ask. My thoughts are that VPN may be the way to go. -- Aaron Clausen
