Would appreciate any help.

I have installed a 3300v+ firewall that sits between the office network and the backup ADSL (via a 2820).

Even though the 'manage through WAN' is disabled I can still get to web interface, ssh etc through the WAN interface. I only want this to be administered through the LAN, not WAN. Is this a bug, or is it dependant on another config?

Anyone experience this? A little worrying that a firewall product doesn't apply this, what else doesn't work?
