Ahh...thanks Brian, it is a different way of specifying the subnet mask. I have now tried your suggestion and done some testing with my VPN. With a routing entry I can get HTTP traffic to be routed through the default gateway. As tested by external IP address checkers correctly reporting my (and not my office IP address). With the VPN running I can use remote desktop protocols to machines on the office subnet (192.168.57.150) so that has to be working too. However, HTTP traffic is slower (i.e. web pages take longer to load) with the VPN running despite being routed via the default gateway. In addition one particular subnet address, that of the VPN server and office router (192.168.57.2), gets routed via my default gateway (192.168.15.5). The attached file shows my routing after issuing "route" in terminal with and without the VPN running. IP of the office X'd out for security reasons only, it showed the correct address. My routing table entry in the VPN is address = 192.168.57.0 Prefix = 24. My understanding is that any traffic to any IP address starting 192.168.57.XXX should be routed via the VPN. Why is traffic to 192.168.57.2 being directed over the default gateway, but traffic to other IP addresses in the subnet is correctly trafficked via the ppp0. Is this a bug in the VPN's routing table or some more global routing issue. Could my browser be using the VPN connection to resolve DNS thus slowing down web access? If so why.

PS. If this is no longer the place for this discussion I will happily continue elsewhere.
