I've got many small sites with Linksys RV042 VPN routers which are doing IPSec VPN back to our main site 1812 router. These VPN tunnels all work great except that I've had to create RTR probes pinging the inside interface of each RV042 to keep the tunnels alive. If any of the RV042 internet feeds drop, the tunnels will not re-establish without manually clearing the crypto on the 1800 router (clear crypto sa) and then they come back up just fine. Has anyone else seen an issue with these RV042 routers? THanks.
