Pulling what little is left of my hair out trying to set up an additional site-site vpn with 2920 routers.
Initially there were three sites so only two vpn's per router, then another site came live but couldn't get it to connect the vpn's no matter what I did.
I have a 2710 & I know that it only allows two concurrent tunnels but the 2920 should allow up to 32.
All the vpn's connect so I know it's not a config error, just cannot get more than two to connect at once.
I upgraded the firmware on one of the routers from 3.6.1 to 3.6.3 but no difference.
Any suggestions?
