IPSEC Tunnel peer network being routed over default wan

[ShaunHirst]

I've created an IPSEC tunnel phase 1 and 2 wav both connected but i'm unable to ping anything on the other side

when i check the routes the a route had been added to get to the remote network but using em0 which is my default gateway WAN1

so the peer network is 10.0.48.0/24 i would expect to see a route that routes this through the vPN but the route shows it going through the default gateway and if i trace route the trace showing it going through the default gateway then across the internet where it should have gone over the VPN tunnel.

also despite selecting a WAN interface in the phase 1 setup all the data was showing at the remote location as coming from the default route.

so for example i have 192.169.101.0/24 as a default gateway and 192.168.102.0 as a second wan i create ether VPN to use the 102 range but the remote site still sees me coming form the 101 address

Thanks in advance fro your help
