Cisco IPSEC VPN client does not work through the router. What should I do?

In the latest firmware revisions for Vigor Routers, the IPSec pass-through function is disabled by default since it conflicts with the new NAT-T feature.

To enable the IPSec pass-through function, telnet to the router and add the following command:

“‘srv nat ipsecpass on’.

To view the IPSec pass-through status enter the following command:

“srv nat ipsecpass status”
