can't telnet to a VPN when another NIC is connected to a private network in CENTOS

I have two NIC. one is connected to a private network. and ip of that network is determined by dhcp.

another NIC is connected to another network. for that network, ip is specifically assigned by the network administrator of that network.

eth0 is connected to that dedicated line and eth1 is connected to my office network.

i'm giving the configuration of the two network.

Code:

ifconfig -a



eth0      Link encap:Ethernet  HWaddr 00:24:1D:7E:5E:4D

What IP are you attempting to telnet too, and what route do you think it should take.

According to your routing table packets will go to eth1 through GW 192.168.12.1.

So should i add a static route for reaching the VPN?

Yes, in accordance with VPN settings.

And may be that page will help you:
