It is a typo, I'm sorry. The host is .2
p default-gateway 192.9.230.179
ip route 0.0.0.0 0.0.0.0 192.9.230.180
But that shouldn't matter as you have a more specific route anyway:
ip route 10.150.2.0 255.255.255.0 192.9.230.179
Assuming that IP address is correct for the local ASA, the next check is, does the ASA have a route for the 10.150.2.0/24 network? I think it does, because from Site 1 you can ping 10.150.2.254, right?
I'll double check the ASA. I know that if I try and ping the hosts from each site, the tunnel comes up and I can see the traffic in the logs.
So all that's left is the host itself.
Can 10.150.1.2 ping its VLAN's router address? Yes, it can.
Can the Site2 email server ping its VLAN's router address? Yes.
Can each of them ping a different VLAN router address? They can - but it goes out the other nic that has a gateway sepcified. If I force the traffic out the NIC that I want the traffic on, it wont see any other vlans.
