[pptp-server] Multiple interfaces on POPTOP server ?

[John Grant]

I want to set up a VPN server which has interfaces on many networks, so that 
connections can be made to multiple (separate) networks by remote clients.

I have set up a few test accounts that specify

username	servername	secret	IPaddress
test-1	*		passwd1	192.168.1.100
test-2	*		passwd2	192.168.2.100
...

you get the idea. Well I can get the authentication and arp -a on the VPN
server says:

? (192.168.1.100) at * PERM PUP on eth1

which looks good, but then if I ping 192.168.1.100 from the VPN server I see

PING 192.168.1.100 (192.168.1.100) from 192.168.0.2 : 56(84) bytes of data.

where is the 192.168.0.2 coming from ? Obviously I'm asking this as the
VPN tunnel doesn't seem to work.

Any pointers ?



P.S. In the syslog I see:

May 23 15:22:29 vpnbox pppd[786]: CHAP peer authentication succeeded for vpn-test
May 23 15:22:32 vpnbox pppd[786]: found interface eth1 for proxy arp
May 23 15:22:32 vpnbox pppd[786]: local  IP address 192.168.0.2
May 23 15:22:32 vpnbox pppd[786]: remote IP address 192.168.1.100

How do I get local address to be on the correct network ?
