Ok so here's my situation. I have a network which has a linux box as
the router and firewall. On that box I want to run a vpn to which I
can connect from anywhere on the net. I have setup poptop on the
server and can connect to it succesfully from anywhere on the net,
however, I can't access any of the computers on the network and they
cannot access my comp elsewhere on the net. What do I have to do in
order to make this link? pptpd appears to create a route when I
connect but obviously it is not work. Reasons? Solutions? Anything
would be helpful. PS. The firewall is not of concern at this moment so
please disregard its existence. Thanks a lot in advance.

I have gotten it so that pinging from either end shows up in
/var/log/messages even though no response is recieved. Here are the
entries from either end:

Sep 22 21:26:47 server kernel: IN=eth1 OUT=ppp0 SRC=192.168.0.2
DST=192.168.0.100 LEN=60 TOS=0x00 PREC=0x00 TTL=127 ID=65209
PROTO=ICMP TYPE=8 CODE=0 ID=512 SEQ=44800

Sep 22 21:29:11 server kernel: IN=ppp0 OUT=eth1 SRC=192.168.0.100
DST=192.168.0.2 LEN=60 TOS=0x00 PREC=0x00 TTL=127 ID=10266 PROTO=ICMP
TYPE=8 CODE=0 ID=1024 SEQ=2304

Here is a copy of my routing table:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref
Use Iface
192.168.0.100 * 255.255.255.255 UH 0 0
0 ppp0
192.168.0.0 * 255.255.255.0 U 0 0
0 eth1
24.78.72.0 * 255.255.252.0 U 0 0
0 eth0
default 24.78.72.1 0.0.0.0 UG 0 0
0 eth0

Hope this might shed some light as to what my problem is. Thanks.
