How are you connecting the BT Infinity to the ASA?
0
 
Jo CoxAuthor Commented:
Directly to the bt white box (modem), not using the homehub. I have been testing the BT infinity line connected like this but to a cisco 1841 and it works fine so I know I have all the credentials correct and that the line works fine.

It's just connecting via asa that seems to be failing!

PerarduaadastraCommented:
The report seems to indicate that it all falls apart as soon as negotiations between the two ends of the connections start.

Have you tried different authentication methods? I know that in theory what works for the 1841 should work for the ASA, but they are very different bits of kit...

Do you mean like pap?

PerarduaadastraCommented:
Yes; that's the only other one, really, as EAP is primarily used in wireless scenarios. However, PAP does seem unlikely as the password is transmitted in clear text - not a great idea!

Another thought has occurred to me; can the term "negotiations" refer to the link characteristics as well? If link speed or MTU size can't be agreed by the endpoints, that won't help much...

PerarduaadastraCommented:
I've just had a look at the connection of one of my clients who uses a completely different device for his connection, and that device provides an option for auto-negotiation of the link; does the ASA allow you to do this?

The Only Auto things available are the speed and duplex.
I have tried fixing these at 100/full and auto. didn't seem to make any difference.

PerarduaadastraCommented:
I've just had a quick chat with my router, which is connected to BT's Infinity modem; the port speed is set to autosense, and the MTU size is default, which the greyed-out Custom field is showing as 1492 bytes.

I have found in the past that connectivity can be broken by specifying the wrong MTU size in the router/gateway/whatever appliance, so it's worth experimenting with at least the common values, unless BT can tell you definitively what it should be.

I'm away from my computer for a few hours now, so I hope that someone else can get you up and running, even if it wasn't me!

Back again.

Another thought:

Have you got multiple public IP addresses on this interface? If so, such a configuration may need more expertise than I have.

It might be helpful if you re-posted this question in the Cisco area of networking, as more expertise is available there than here; so far, it's just been me!

Hi Perarduaadastra
There are multiple connections as the asa is live with a lan a different WAN connection.

I'll take your suggestion and repost to Cisco area.
Thanks for your help.

That's very generous of you, since my only useful suggestion was for you to ask someone else!

A better use of the points might have been to move the question rather than repost.

Perhaps a moderator can arrange this for you, as I feel rather uncomfortable about receiving points I didn't earn...
