I have an odd issue here that I'm not sure what would be causing it.
We have a main office with a VPN 3005 concentrator, and multiple construction sites connected to it with VPN 3002 HW clients or ASA 5505s.
Home office (PVT): 10.0.x.x
Remote Site 1: 192.168.11.x
Remote Site 2: 192.168.12.x
For some reason Site 1 cannot ping Site 2 the first time, unless you initiate a ping from Site 2 at the same time.
Once you run the ping command from both HW clients at these locations, they respond fine until the power is cycled. The routes seem to be fine, but I'm not sure what would cause it to timeout unless a ping is initiated from both ends?
Further documentation can be provided if requested. I just wanted to see if it was something simple I was overlooking.
192.168.11.x pings 192.168.12.x - Timeout
Site 1 and Site 2 ping each other at the same time - Reply
After success - Site 1 can ping Site 2 without Site 2 client initiating ping command
