Known Issues and troubleshooting tips
- By default the VPN client tunnels all traffic through the firewall. This is not under the firewall administrator’s control, and is purely a client issue. We have allowed internet browsing through the VPN tunnel, but you may notice a marked increase in your browsing latency. The client does allow you to “split-tunnel” and send only the required routes through the tunnel. This can be done by editing the properties of the VPN connection, browsing to the IPv4 tab and selecting the routes button. Make sure to select the option Use this connection only for resources on it’s network. You may also need to enter the routes manually in the table.
- You may notice periodic disconnects or loss of connectivity. This seems to be due to a bug in current VPNC versions that have issues with rekeying. Research on google should turn up some suggestions
- Generally all errors and debug messages are logged to /var/log/syslog. Check this location if you run into problems.
