NF4V Virtual servers

Hi all

I have a slingshot supplied NF4V modem router from ADSL days. I am now on a fibre contract.

I have some virtual servers setup for port forwarding. The problem is there are none listed. If i add a "server" it returns to the server page but the list is empty, If i add it again it says it already configured.

Tech support wont support the "Virtual servers". I ok with this but the missing list is the issue. If i want a new modem i have to break my contract ($250 fee) and re sign up for 12mths, plus $15 courier.

Anyone else have this problem?

Cheers
