General Questions

hi
I'm running monowall on a net4801 soekris box.  I have these boxes running at a lot of (10) sites with no problems.  At one site webmail.shaw.ca (also some survey monkey addresses) is blocked.  Interestingly this is the only site that has Shaw cable as an isp.  I can see that webmail.shaw.ca is blocked in the log, but I just see the ip number being blocked, it doesn't give a port number.  If i create a rule to allow that ip number it still blocks it.  Is it something to do with being within shaw's ip space?
All my firewalls are configured the same, as a filtering bridge.  These have very successful for me, so this is very confusing.
Any ideas??

A few more things.  I've flashed a new CF card and reconfigured the software from scratch and still have the same problem.
I just found out that some other secure sites have this problem there, like amazon.com.  While other HTTPS sites are fine.

Could it be that somehow the port information has been stripped off before it gets ot the firewall, and that's why it won't be passed???

or could it be that these sites use a java app as well?
