All
I try to keep my subjects pretty straight, but this time I'm not sure if I can do it.
I have ASG 7.0 on a cable modem. Computers NAT'd behind it include:
XP Laptop - often RSA VPN'd to the office - all traffic is routed through to the office and this becomes my test box. The laptop works 100% as expected. With the VPN dropped, I can also log into MSN Messenger.
XP Desktop 1 - works fine and is now a backup server. All pages load and MSN Messenger will sign in (including www.grc.com). No problems with this one at all.
XP Desktop 2 - Wife's - Some web pages will not totally load - www.grc.com as an example. Messenger also fails to log in. You also can't make it to a secure login for printing a boarding pass at Air Canada for example.
Vista Desktop - www.grc.com will not load and the same test at Air Canada for a boarding pass. Windows update will not function.
I have a MASQ rule set the single internal network to External Wan. Web security is set to Transparent.
This is a Home setup, so we don't have to be as secure as an office, but are there some basic ports that are opened that I might have missed beyond the wizard? I'm not an expert by any means, but I'm pretty confortable with my network skills (not that I don't have more to learn).
I can set up proxies if need be, but from what I know, do I need them. The funny thing is that some boxes work just fine, some don't and I don't see any reason why the failing ones fail. If I replace the ASG with a Linksys WRT54G they work.
As for HTTPs: some pages fail, some don't. Banking on all computers is fine.
Any ideas/suggestions.
