I should connect to a Cisco VPN server for example 95.94.66.6, it configured to accepts specified IPs so I launched a server with a registered IP on Cisco which runs an openvpn server. The scenario is like this: I connect to my vpn server then connect to Cisco with vpnc-connect command on client. All thing to here are OK. The problem is that when I connect to vpn server all internet traffics goes out through it. To avoid it I changed server.conf on vpn server and disabled push "redirect-gateway def1 bypass-dhcp" and added push "route 95.94.66.6 255.255.255.255 vpn_gateway 1" then restarted the openvpn server. After connecting on client, routes are ok, also there is no 0.0.0.0/1 and 128.0.0.1/1 as expected. I have the ping of the 95.94.66.6 and correctly traceroute. But vpnc-connect failed and says no response from target. I rolled back the configuration and this time vpnc could connect. Also I checked the routes and iptables on vpn server and client and there is no difference while using two different config.
Why? and How to fix it?
