I recently deployed UC560 on my customer site and I had problems with pppoe internet connection. I tried various scenarios but nothing worked.
First I tried setting it up behind D-link adsl modem in bridge mode (Witch worked on site with software router/firewall). then I tried with my thomson tg780 also in bridge mode. All configuration is setup only by cca 3.2 as recomended in one situation i noticed that i got dns servers addresser from isp and nothin else. To temporeraly enable internet connection I set up thomson as router and UC wan connection as static IP.
Becouse I must deploy VPN and other features of UC i realy need to solve that problem.
I would apritiate all advices.
