I'm trying to set up a lan-to-lan tunnel between the two pix firewalls, and the only way I can get communication goin between the two sites is if I initiate traffic from both sites at the same time (before the tunenl times out)...once that's done as long as I have traffic going accross it's fine, but if I stop sending traffic I have to recreate the tunnel by re-initiating traffic from both site. I'm guessing it's a problem with the edge routers...on the london side I'm getting this error (note this router is only supposed to forward traffic to the pix, no tunnel is supposed to be created on this router):
