VPN cant ping L2L ip address but can ping anywhere else
I am having an issue where our VPN Concentrator 3000 is able to ping out and do traceroutes to external ip addresses but the IP Address that I need to connect to, to establish a L2L VPN Tunnel does not respond. Though, I am able to ping that IP address from our core switch and router but cannot ping to it from our VPN Concentrator. Our Concentrator faces our modem and uses that as a default gateway so there is no internal hops. Any help on this would be much appreciated.
