Serious MSN and Skype problems

Hi everyone;

I have a serious problem in my network that no one can connect to MSN or Skype. Sometimes when I restart my RB they able to connect for a few mins than again off.

Setup is;

RB 532 + 502 === 3 x mpci — running hotspot on them
x86 = Running User manager

I dont have any Filter Rules to block anything but it happens.

Any idea ?

Thanks

Do you use NAT? If so, enable connection tracking.

/ip firewall connection tracking set enabled=yes

connection tracking is enabled.. customers are not able to have connections to secure sites, MSN and Skype too..

any opinions ?

In case you do not have any firewall restrictions.
Check the next-hop routers or complain to upstream provide.

thanks for your comments
