I am running ISA 2004 in 2 locations. I ahve established a PPTP static tunnel in both locations for replication. One side works fine while the other side won't connect. The locaton that it 's connecting to gives me an error in the ISA log so I would imagine that this is the problem.
The ISA Server detected routes through adapter 3Com Etherlink PCI that do not correlate with the network element to which this adapter belongs. For best practice, the address range of an ISA server network should match teh addess ranges routable through the associated network adapter as defined in the routing table. Otherwise vailid packets may be dropped as spoofed.
The address ranges in conflict are: 192.168.75.255-192168.75.255; 192.168.80.255-192.168.80.255.
The thing I don't understand is that the 3Com adapter is my external adapter not my internal. Can anyone walk me through why this is happening?
