I am using PfSense as a firewall, with its VPN functionality. The client I use is Shrew Soft VPN client. As it is a split tunnel, is there a way I can force all traffic through the VPN connection, i.e. so my external IP is always the PfSense box's one.
The reason I would like to do this is because the locations I access my servers from has DHCP assigned addresses via the ISP. I cannot afford a static IP, it isnt included in my package, but I lockdown my servers to only some IP's. When the ISP allocates a new IP, I am unable to access my servers through SSH. I have allowed the IP of the PfSense box as it is in a location which has a static IP.
How would I overcome this, is there an alternative to trying to force the traffic through the VPN tunnel?
Thanks in advance for help.
