I have two Linksys RV042 routers at two different locations (Main Office and Alabama Plant). The VPN between the two locations is connected. However when I use the diagnostic utility on one router to ping the other, it only works one way (From the office) -- when I try it the other direction the ping times out. I also can't ping the remote network from my computer at our Main Office.
What configuration issue would cause this? I've been through the config on both routers and they appear to be as near identical as possible. This is an issue that has popped up only recently. Any help would be greatly appreciated.
