CAP (Calendar Access Protocol) port

[DouweQuerty]

Hi,

I am running zimbra in an unbuntu jail in gentoo and it is running smoothly even through my firewall. But when I checked my firewall logs every few minutes to few seconds UDP port 1026 and 1027 are mentioned (I log every package just above the drop all rule). After some research I found that these are Calendar Access Protocol ports which makes me beleave these are incoming connections for zimbra. Unfortunately this port isn't mentioned in the zimbra documentation or wiki thus I will ask here : Is this an zimbra incoming port and should it be opened in order to use the calender properly ? I haven't had any complains about functionality of zimbra but that maybe because there are only few users.

For clearity : It is about INCOMING connections from the internet to UDP port 1026 and 1027.

PS I drop incoming connection to port 161 (SNMP) too

I don't think these ports have anything to do with the Zimbra calendar. A quick Google search turned up that seeing incoming traffic on these ports is quite common, and it is typically associated with Messenger Spam.

Ok thnx ... no zimbra port
Well I googled too and found out the CAP service is bound to this port thus I wanted to be sure.
