G'Day all,

that has a poptop server on it. When a client logs in they get authed
fine and get issued an IP. However when connecting or pinging no data
comes back from the server. arpproxy is set, as is forwarding.
net.inet.ip.forwarding: 1
net.link.ether.inet.proxyall: 1
The server for some reason puts a route for the client ip on the
ethernet interface rather than the tun interface the client has come in on.

As you can see the client (10.10.1.34) is routed on the fxp0 interface
rather than the tun1.
Anyone got any Ideas?
Cheers
