I have two networks, in two different locations connected by a point-to-point MetroE. I have SSG 140's configured on each side:
Building A
Eth 0/4 10.0.100.1/24 Trust zone
Eth 0/7 10.0.200.1/30 Trust Zone (connected to P2P MetroE)
Route 10.0.200.0/30 C Eth0/7
Route 10.0.200.1/32 H
Building B
Eth 0/4 10.0.110.1/24 Trust zone
Eth 0/2 10.0.200.2/30 Trust Zone (connected to P2P MetroE)
Route 10.0.200.0/30 C Eth 0/2
Route 10.0.200.2/32 H
Gateways and AutoIKE is all configured correctly - the tunnel I created came up and was working great. Lasted about 18 hours, then went down. I assumed the ISP was having issues, but they say everything is fine, they can ping both side of the tunnel they created for my P2P. Any ideas?
