I removed the bound to internal part of the Lab Network definition, and checked all of the ICMP/PING/tracert options, but I am still unable to get the ASG to route from the LAN to the LAB.

from 192.168.1.112 I can ping, telnet, whatever to 10.8.5.30 only if I put in a local route:

route add 10.8.5.0 mask 255.255.255.192 192.168.1.29

Without the local route, the GW on the 192.168.1.112 host is 192.168.1.1 (the ASG) so it seems clear to me that the ASG is not then sending the traffic on the 192.168.1.29. Nothing shows in the packed filter log. Tracert shows 192.168.1.112->192.168.1.1->WAN ISP ips.
