which port is used for comodo update?

hi…

i’m trying to update my comodo internet security, but in my network there is a internet server that blocks the access for some users, working as a filter blocking some sites, msn, etc…

i need to unlock the port used for update in this server

somebody can help me?

I used the Active Connections Viewer while updating and saw only traffic happening at port 80 for cmdagent.

Can you tell us more about your problem? What OS are you on and what version of CIS are using? What is the error message you get?
