Cannot Connect to Web Host After VPN Connection Is Made
We recently upgraded to the Watchguard Firewall. After the upgraded we started having problems with the cisco vpn client. The cisco vpn client can connect to the outside host. However we cannot log into the website for the host now. A logon prompt does come up but the it fails. We call the host and verified that all the login information is correct and active. This problem is so perplexing because we have no problems accessing any other websites. It seems to have alot to do with pulling up this one website after the vpn connection is made. BTW once the vpn connection is made one and only one website can be pulled up. The vpn connection does not only any other host to be browsed on the internet or locally. Any ideas on this one? Thanks for any help in advance...watchguard tech support is horrible.

Software Firewalls
Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

If you are so equipped, you could put a protocol analyzer on each machine, and tell for sure which packets are making it through, and what isn't. That may help you narrow this down.
