Hi all, we have upgrade our ac from v6 to newest v7.12. after upgrade all mpls ospf works fine but customers they comes over this ac cant open >90% of websites, but they can ping websites and tracert works too. Websites dont open in browsers.
Custs tell, small websites can open, >= 90% cant open and small do load very slow.

A ping of a v6 mt before of v7 ac with 1500 dont fragment works fine.
But why customers cant open websites in browsers, if ac was on v7. Downgrade back and restore config in v6 works fine back.

Hope you can help to fix it and have a idea here^^

regards
