Had been using tik to do pppoe login to dsl bridge for months no problem. Then one day we could no longer access it through the tik. PPPoE connects and all looks good but can no longer get out to the internet. I assume something changed on the providers side (CenturyLink) but since their westel router works fine, they will not offer any further input on the issue. If I change connection to DHCP and let the westel modem handle pppoe, all is fine. I suspected something with MTU but wasn't able to find a setting that worked. Anyone one else had this? Any suggestions.

No i dont think its an MTU related issue...
