Firewall port 1105 (FTRANHC) & port 1239 (NMSD) ?

Can someone shed light on this message from Sygate Personal Firewall? Firefox (firefox.exe) is being contacted from a remote machine

[66.102.7.104] using local port 1105 (FTRANHC - FTRANHC). Do you want to allow this program to access the network?

1. I brought up firefox and went to google groups.
2. Sygate asked me if I wanted to go there at port 80 & I said OK.
3. Then, Google came back asking to come in on port 1105. Why does Google want to remote initiate at port 1105?

Then I search for port lists and find this URL:

When I go to that link, besides the request to go out on port 80 I get another incoming Sygate permission request asking: NDIS User mode I/O Driver (ndisuio.sys) is being contacted from a remote machine

[68.178.160.90] using local port 1239 (NMSD - NMSD). Do you want to allow this program to access the network?

I say no, and the web page won't come up.

So I go to

to find not much on these two ports.

My confusion lies in why these web sites feel the need to contact me on any port other than the port 80 that I go out to them on.

Can you shed light on what is the normal process here?

Thank you for your guidance, Ellen
