Some HTTP traffic is dropped : eoor message 'A non-SYN packet was dropped'
Got a freshly installed ISA 2004 Firewall running, with rules for webservers, SMTP, VPN etc all setup and working.
However, we've got an IP camera which we're having problems with. If it sits outside the firewall, it functions fine, but if accessing through the firewall some of the images don't display. The IP camera uses HTTP on port 80, and we don't have any problems accessing other websites.
Changing the firewall rules to open up access on all protocols (effectively removing any firewall blocks) makes no difference, but the firewall is definately the cause of the issue.
Running a log shows the message :
