Hello everyone, I hope this is on-topic for the list...
I'm familiar with NAT, but I can't see how to route a fully routed LAN. My new ISP has given me a /29 (I understand this to be 6 addresses + network address + broadcast address) which I would like to use, as multiple PCs here want to use p2p and games at the same time, and reconfiguring the port forwarding all the time is getting pretty silly. I'd also like the experience, since I've been messing with traffic, IDS and NAT for a while and I'm more interested in larger networks career wise, and they are typically not NATed.
So how do I do this? Do I have to rewrite all the iptables/ipchains myself? Can e-smith or freesco or ipcop understand what I'm doing?
Is there a way to test that the ISP is correctly routing the /29 traffic to the IP I get for the external link? I suspect anything I may do will be a waste of time if the ISP is misconfigured on their end.
My early scratchings around the net indicate that "real" firewalls don't want pppoe, and pppoe distros want to do NAT. There's also a lot of discussion about how pppoe sucks compared to static IP but here in Australia the economics don't work so well....
Any help, advice or abuse would be welcome!
