Are you pinging by host name or by IP?

I found that specifying a DNS server manually in the PPTP connection
settings helps (ie monowalls IP if that is your local DNS server aswell).

I currently use PPTP passthrough to a Windows DHCP server, so it assigns DNS
automatically.

Subject: [m0n0wall] Cannot ping hosts across PPTP vpn reliably

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 assigned, yet.

Thanks!

Joe
