I'm using openswan to link two machines via IPSec. The tunnel comes online fine and I have connectivity to each endpoint via the VPN.
However, when the tunnel is up, I lose connectivity to the public endpoint IP addresses. For example, pinging site A public address 18.104.22.168 from site B public address 22.214.171.124 (and visa versa) fails.
When the tunnel is up, I noticed something curious that could explain this behavior.
#ip xfrm policy src 126.96.36.199/32 dst 188.8.131.52/32 dir out priority 2080 ptype main tmpl src 0.0.0.0 dst 0.0.0.0 proto esp reqid 0 mode transport
I snipped out the reamining output as it only contains entries that make sense (the private networks connected by the tunnel).
Any ideas what I'm missing?
