this is a valid point, you could indeed by using iptables or maybe even
netfilter transperant proxy traffic from the three APs to a different
port and have three dhcpd servers running...
have a look at these docs to get a better idea of where to start;
- Linux Advanced Routing & Traffic Control
- Linux 2.4 Packet Filtering HOWTO
- HOWTO: Transparent Packet Filtering with OpenBSD
- Linux 2.4 NAT HOWTO
- Linux IP Masquerade HOWTO
maybe source and destination NAT maybe a useful bit of background
reading, and also the IP Masq howto, esp. the FAQ section.
there are similar documents for other BSDs if thats your poison =)
anyone have links for those?
