I have a new 515E (192.168.6.10)routing to(192.168.5.254)(1721 router)to another 515e (192.168.2.1)to get to the internet( separate corporate networks). I am able to put the ip address in IE6 and get to the site, but when I put www.yahoo.com, site no...

I have a 515E firewall that about every two weeks just hangs. I heard through our T-1 provider that there was a field notice or recall out on this issue, but can't find anything that is later than May 2002. Is there something newer to review?Thanks
