Hi Mat,

I've used the config below with Eircom. You'll need to tidy up the NAT bits...

Eircom are fans of PPPoE rather than the PPPoA (Generally used) elsewhere in the UK, which is the biggest catch with them I find. There is a pretty good online config here:

However if you want to post your config up (less passwords) then I can take a look and see if I can spot the issue.
