Question Remote Subnet Mask? - help!

I've just setup a new dial-up ISP which works fine through a hardware terminal adapter but I can't get it working through my ISDN Router.

The router (D-Link DI-106) diagnostic says "Remote Subnet Mismatch: confg'd:, neg'd:". However, the router's Remote Subnet Mask field is actually set to
I've tried changing this to '' but the connection just drops out the same.

I don't understand why the router is saying 'configured:' when it is actually configured as '' or how I get it to connect to the 'negotiated'?

Can any TCP-speakers translate for me?

Well strictly speaking your not dealing with TCP at the mo, you are dealing with a protocol called IPCP, a subcomponent of PPP which can be used to negotiate link addresses. Not that that helps you in any way!

If the router is negotiating an address with your ISP, then you should not be configuring any address locally to your router. and aren't valid subnet masks anyway, they are non-contiguous bit sequences, so I'm not quite sure whats going on there!

Look in the manual there should be some sort of setting to make the local wan address "assigned" or "negotiated"

If it was a cisco I could help more!!
