VPN banned

[bob]

Hello DSL'ers

I have been successfully using IPSec VPN tunnels over ADSL for some time now. NOW it has stopped. I know that IPSec connects to remote firewall on port 500. Is this port being blocked / banned?

Does anyone else use VPN on ADSL.

Any help, much appreciated.

I use CISCO's vpn 5000 and 3000 clients to connect to my corporate network. Due to port prioritization it get's very slow during the day. Fortunatly I have a secondary secure tunnel method to get in to the network that only uses port 80 with out being affected.
