I was having a problem connecting with ActiveSync when I first installed PF, I saw a post a while back on Active Sync which I applied (pasted below). Everything worked well after that for several months, however suddenly the problem is back and I cant connect with ActiveSync when PF is running. Other than regualr updates PF downloads nothing new has been installed on my system.
It seems activeSYNC needs some local ports(5721/990) to be allowed.
What you need to do is:
1- Go to “Security->Nework Montitor”,
2- Right click on the first rule(Rule Id = 0)
3- Select Add Rule->Add Before
4- Action “Allow”, Protocol “TCP”, Direction “In”
5- Source IP : “Single IP” = “169.254.2.1”,
6- Remote IP : “Any”
6- Source Port : “Any”
8- Remote Port : “Any”
9- Click Ok button.
Now your first network control rule must be : Allow TCP IN FROM IP 169.254.2.1 to IP ANY WHERE SOURCE PORT IS ANY AND REMOTE PORT IS ANY
