 |
|
Hi,
I have openvpn (routed setup, not bridgeing) running at my work. When I connect at home to the VPN, it is working flawless, but when I disconnect the VPN, my default gateway is not restored.
Here is the ouput:
1.) before I connect to VPN
| Code: | hive marc # route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 |
2.) VPN is running:
| Code: | hive marc # route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
[IP of firewall] 192.168.0.1 255.255.255.255 UGH 0 0 0 eth0
10.8.0.10 0.0.0.0 255.255.255.255 UH 0 0 0 tun0
[subnet 1 behind firewall] 10.8.0.10 255.255.255.128 UG 0 0 0 tun0
10.8.0.0 10.8.0.10 255.255.255.0 UG 0 0 0 tun0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
[subnet 2 behind firewall] 10.8.0.10 255.255.255.0 UG 0 0 0 tun0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 10.8.0.10 0.0.0.0 UG 0 0 0 tun0 |
3.) VPN is stopped:
| Code: | hive marc # route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
[IP of firewall] 192.168.0.1 255.255.255.255 UGH 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo |
If you compare 1.) and 3.), you can see, that my old gateway is not restored. Does anyone know, why this is happening and how I can resolve this problem?
Thanks in advance

If of any interest, the problem was, that I downgraded the user privileges to nobody:nogroup after successfull initialisation (option user and group). When I stop openvpn, the proces does not have root rights anymore, therefore it cannot change the routes back.
