When we try to access www.heemskerk.nl, we get a 504 gateway timeout.
We have a Bordermanager 3.8 SP3-proxy on Netware 6.5 SP2-server.
The Bordermanager-proxy is behind a PIX-firewall.

When we use a Windows 2000-workstation with a direct connection with
internet, we can reach www.heemskerk.nl without any problems.
