I have a Vigor 2910 and have recently connected a second line to the WAN2 port. I think the following problem would also apply to the 2820.

This is working fine except for a problem with port forwarding.

In Port forwarding you have to select WAN1 or WAN2 – namely, the setting is specific to each incoming line.

So I now have to specify all my port forwarding all over again for WAN2.

This is a major pain. First I have repeat all the forwarding again. Much worse, as I am using more than 10 of the 20 slots allowed I cannot actually set up all my setting for WAN2.

Is there a way round this? Is it possible somehow to select an “ALL” option in place a specific WAN port?

It seems a strange omission not to allow “ALL”.
