PPTP problems (got connection, now what?)

I recently configured PPTP on my RH 8.0 machine to connect to a
Windows 2K box at my office over RoadRunner. The connection comes
up successfully and I can see my machine connected on the office
server. That's the good news. The bad news is that I can't see
the office network. I'm trying to connect to an HP-UX machine via
it's IP address but when I try to telnet in it says it's trying
but just (eventually) times out.

netstat -rn shows:

Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
128.223.8.1 0.0.0.0 255.255.255.255 UH 40 0 0 ppp0
111.222.2.0 0.0.0.0 255.255.255.0 U 40 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 40 0 0 lo
0.0.0.0 111.222.2.1 0.0.0.0 UG 40 0 0 eth0

I can ping the remote tunnel address but that't it. Nothing else on the
remote network responds. Any help, hints, or suggestions would be much
appreciated.

Thanks,

I think you need a network gateway route for the subnet to which the MS
host belongs (I can't be entirely sure since I don't know exactly how
PPTP works).

If the eth0 default route above is really necessary, i.e., it's not
just attached to a leafnode LAN, then you can add

/sbin/route add -net <subnet_on_MS_side> gw 128.223.8.1 $1

to the /etc/ppp/ip-up script that pppd executes when PPP comes up for IP.

Otherwise delete the default route to eth0 and add the pppd defaultroute
option.
