Sounds like your VPN is not sending all traffic through the remote
router. You are doing what is called a split tunnel. Only traffic
destined for the remote routers local subnet is going over the VPN and
everything else is going directly over the local internet connection
unencrypted. So if you were doing this as a form of security on a
hostile network like an open wi-fi then you are likely transmitting
everything you wanted to be secure in to the clear.
If the remote network subnet in your IPSEC configuration is not 0.0.0.0
(aka Send all traffic to remote VPN server) then you have a split tunnel.
