Kirton, is the 7100 doing firewall? If not, is the Cisco set up to route the 10.10.20.0 subnet over the VPN? The trick would be to makes sure that you can ping the voice VLAN IP address of the 7100 from the remote site and the remote site while sitting behind the 7100. Please reply with the 7100 config. Thanks
Thanks for responding and sorry it took so long to reply. I got the issue sorted, we had to conenct it to the front of the netvanta and set up the routes correctly on the cisco routers. Once that was done everything worked.
