I have set up a VPN using these instructions.
http://www.netbsd.org/docs/network/ipsec/rasvpn.html
and have been able to make a connection and ssh into the vpn node.

However, I unable to contact other nodes on the network.

Things of interest.
NetBsd 4 rc 2 (VPN Node)
Runing pf on vpn node.
Fedora 7 remote node
vpn node = 192.168.0.10(wm2) and 192.168.0.1(carp1)
internal node= 192.168.0.100 - gw 192.168.0.1
remote node = 192.168.0.200

tcpdump on internal node while ping from vpn node.
09:54:00.883379 IP 192.168.0.10 > 192.168.0.100: ICMP echo request, id

I also see this
09:56:16.197056 arp who-has 192.168.0.200 tell 192.168.0.100

What did I miss?
Thanks
