Hi Guys,

 

I've recently got a BT Infinity business service with 5 static IP's and it came with BT Business Hub 3. I have a cisco 1712 modular router with 4 port switch module installed. I wanted to use this router instead of Business Hub 3. I saw some posts and configured but can't configure ip tcp adjust-mss on the switch module. Can anyone please help me. I also need to set it up for Static ip. I'm pasting the link i got and my config below.

 

Which cisco router is working best on BT infinity?

Hi

 

Did you ever get your 1712 working on your BT Infinity? Reason I ask, the BT business hub does not do it for me and I have a spare 1720 with a 4 port switch card in too.

 

The main ask, how did you get on with using the '5' ip addresses BT have given you and the CISCO router?

 

Even if you abandoned the CISCO route, what router do you use that works with BT and their implmentation of the '5' ip address service?

 

Cheers
