I have an ASA 5510 Security Plus Appliance which enabled with Remote VPN access. I faced a problem is that my VPN users using IP phone communicators are unable to talk to eachother.
Only when i enable the option < to allow traffic from two or more hosts connected to the same interface> then my VPN users are able to communicate with eachother using IP phone communicators.
However this is a global command as it will be enable for all interfaces i have in the firewall. Is there any work around as enabling this option i feared there is security risk.
Please help me asap as there is urgent.
