Hi,
I have a router with VPN server (npppd). LAN net is 10.109.3.0/24, gw
10.109.3.254, the VPN net is 10.109.4.0/24, gw 10.109.4.254.
If the client is conencted to VPN all client's traffic to 10.0.0.0/8 goes via
10.109.4.254
client> route print
Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.101
20
10.0.0.0 255.0.0.0 10.109.4.254 10.109.4.1
21
10.109.4.1 255.255.255.255 On-link 10.109.4.1 276
[...]
I need to redirect the traffic to 10.109.4.254 only if it goes to the remote
LAN (10.109.3.0/24), the rest should go via def gw.
How can I configure it on the router/server side ?
$ cat /etc/npppd/npppd.conf
