I have a gre tunnel configuration with OSPF tunneled through it.
One of the tunnel routes is on a very chatty link, and it seems to interfere (somehow) with IPSEC tunnels on other IPs (and other devices) in its subnet.
(Im really not seeing any other reason for other IPSEC tunnels on its subnet, constantly having their SAs expire, forcing the tunnels to start up again).
Is it possible to restrict traffic on the link to its tunnel partner, and their associated IPs? (Some sort of firewall deny rule)?
Thanks in advance.
