OpenBSD 3.8 stable

Cable connection to remote town

Normal internal network IP's are DT 192.168.10/24, Remote 192.168.8/24 

When pinging and endpoint from one end of an IPSec tunnel to the other, 
occasionally the ping returns with one of the 10.X.X.X IP's of a router along 
the path. The router IP shows up on traceroute and is more often than not the 
same one, last hop before the firewall . We see this happening when receiving 
a complaint from the small town users about not being able to login to the DT 
servers. After what is usually a brief period, they login and the pings 
return to normal. This can roll along for weeks without issue, (other than 
high latency issues), then a few days in a row this happens. 

As one would expect the cable company, when queried about this, never has any 
problems with their equipment. DSL is not available where they are at

Main question is this, why does the 10.x.x.x address come back to us instead 
of timing out??
