WSUS client won't update when behind firewall.
Posted on 2011-02-24
I have a couple of servers that are behind a firewall. The firewall is configured to allow the servers to talk to the DNS servers, Domain Controllers, etc. WSUS is not working correctly on those servers, however. I have ports 80 and 443 open in the firewall, but Wireshark suggests that there is a dynamically allocated port that the servers and WSUS attempt to talk on. Those ports, in the 55500+ range, are not open in the firewall. Is there a way to make the servers and WSUS talk on a static port instead of a dynamically allocated port?
