I setup vpn services on a Bordermanager 3.6 (up to date with all
patches). The server is listening on port 353.

I can connect to the vpn from the internal network but when I dial up
my ISP and try to connect to the vpn with the external ip address I
telnet to port 353 and get the error

"failed to connect to the authentication gateway
Either X.X.X.X is an invalid VPN server address or the authentication

gateway is not loaded."

I can ping the ip address. I have also tested above with filters off.

The ISP assures me that port 353 is open. I do not know if there is anything else I can do to test this before I decide not to believe the

ISP. Any response is greatly appreciated.

Thanks -Bonnie
