I am having a little problem, I am using a VPN (with openvpn), and it starts auto when the server starts, the problem is that every time I have to set something like this

route add -net 10.108.**.** netmask gw 10.108.**.**

If I make a ifconfig its the eth0 and eth1 and lo and tap0

Link encap:Ethernet  HWaddr 1a:ad:6b:69:3c:83
inet addr:  Bcast:  Mask:
inet6 addr: fe80::18ad:6bff:fe69:3c83/64 Scope:Link
RX packets:481 errors:0 dropped:0 overruns:0 frame:0
TX packets:7 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100

and I dont understand why doesnt work, at my interfaces I have

up route add -net 10.108.**.0 netmask 255.255.255.** gw 10.108.**.1
down route del -net 10.108.**.0 netmask 255.255.255.** gw 10.108.**.1

So, I have to write this

route add -net 10.108.*.0 netmask 255.255.255.** gw 10.108.**.1

Any idea of what could be???

(I use Debian6)

What type of VPN are you running? Is 10.108.**.1 on the other side of the VPN? – Zoredache Feb 22 '13 at 1:33
yes, that is the other side of the vpn – user156355 Feb 22 '13 at 16:28

I suspect you are having an issue relating to timing. I suspect the VPN link isn't fully established when your route statements are being run. If I were you, I would look really closely at the VPN tool you are using, and use the functionality within the VPN to update your routes once the connection has been established.

yes, I think its that too, any way I can solve this problem? – user156355 Feb 22 '13 at 16:28
Like I said, set the route in the VPN. Since you haven't said what vpn you are using I can't really sat much more. – Zoredache Feb 22 '13 at 19:30
