Hi guys.
I have two subnets with static public IP's.
Both point to my hardware SDSL router.
One is 80.123.16.64-80.123.16.71 with 80.123.16.65 as the router IP and the other 123.234.173.128-255 with 123.234.173.129 as the router IP.
I have LAN behind my firewall. It uses 80.123.16.66 to talk to the outside. 80.123.16.66 resides on one nic with a couple extra 80.123.16.64/224 IPs aliased on it.
I run natd and NAT these IP's to misc services behind my firewall.
When I add both 80.123.16.66 and 123.234.173.130 to my firewall I can connect to and from my LAN fine.
I can ping both IP's from inside and outside and connect to the services on my DMZ and to my LAN boxes.
But I also have a few boxes on the 123.234.173.128/128 subnet connected directly to my switch which is connected to the router.
When I add 123.234.173.130 to a separate nic on my firewall, I cannot talk to the other boxes on that subnet anymore, even though they are not connected
to my firewall but directly to a hub. Every connection attempt from the LAN or outside fails.
But then I can speak to 123.234.173.130 just fine.
One more thing. I have 80.123.16.68 also connected directly to my switch and it works just fine. I am pretty confused.
Any idea what can cause that?
INTERNET -> Router with 80.123.16.64-71 & 123.234.173.128-255 -> 3com Switch -> Firewall with 80.123.16.66, 80.123.16.67, 80.123.16.69 & 123.234.173.130 -> Lan & DMZ

A few boxes with public IP's - on both 80.123.16.64-71 & 123.234.173.128-255 and firewalling directly on them.
Another thing, can I run natd on two different nics? Something like natd_interface="dc1 xl0" ? I want LAN and DMZ to use 2 different gw IP's.
Thanks in advance.
