So I've noticed that whenever I visit a adobe flash site I get entries in my outgoing
iptables logs like
netfilter:out dropped: IN= OUT=eth1 SRC=192.168.1.79 DST=184.108.40.206 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=15830 DF PROTO=TCP SPT=46964 DPT=843 WINDOW=14600 RES=0x00 SYN URGP=0
I discovered this port 843 is to do with Adobe's Socket Policy Server.
1) Given these packets are not getting through, how is it that flash content loads and plays fine? (Any benefit in me opening this outgoing port?)
2) Is the purpose of the policy file to decide which sockets on my home computer flash can use, or is it asking its host server what sockets it wants the client (me) to be allowed to connect to the web server on?
