Hello,

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
to
my ISP and try to connect to the vpn with the external ip address I
cannot
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
