I am having a very strange problem. I have setup m0n0wall PPTP VPN's
at multiple locations with no problems. At this one particular
location, if I uncheck "use default gateway on remote network" (in the
windows PPTP vpn config), I am not able to reliably ping hosts on the
network. They will typically time out.
However I can ping .1 (the m0n0wall LAN IP) and .224 the PPTP gateway.
If I use the ping function within the m0n0wall GUI, and am able to
ping the hosts. If I switch my VPN settings to use the default
gateway, I am able to ping the hosts.
Has anyone run into this? Would it have something to do with Proxy
ARP? I do have multiple IP's assigned in Server NAT. But I am
VPN'ing to the WAN IP, and am not using the other IP's I have
