[44net] no more 44-net routing through amprgw?

During my tests yesterday (to get RIP working with a multicast socket) there was an extended period where there was only a default route in my table 44 which is used to send network-44 traffic. This default route sends the traffic to amprgw as tunneled traffic (ipip). This route is normally used only for traffic leaving net 44 to the internet, and more specific tunnels are used for all gateway stations. But this temporarily did not work while I was debugging and the RIP packets were not being processed. What I noticed was that I lost connectivity to the other network-44 stations during that interval. I would expect that amprgw would forward the traffic to the other stations. Of course this is not a desirable permanent situation, but I think it worked in the past. Has this forwarding been blocked in amprgw? Or is this something that must be caused by a local configurarion error here? (like a firewall issue) Rob
