I have a site with an ASA 5510 at the central site, then 871 and 831 routers at the remote sites.
The remote sites all have EasyVPN VPN tunnels back to the central site using network extension. I have split tunneling configured so that only traffic for the central LAN and other vpn sites are sent over the tunnel.
This works great at first, the sites connect and both routes are listed in the tunneled networks. I can reach everything i need to. The problem is not alot of traffic, if any, is sent over the tunnel for the 10.99.0.0/16 network and it is being removed from the tunneled list. I then need to force the remote routers to renegotiate their tunnels by doing a disconnect for it to work again.
The 192.168.1.0/24 network has never been removed, its only the 10.99.0.0/16 network.
Is there a way to stop the IPSec tunnel from dropping that subnet?
