I installed our Netscreen firewall on Friday. (Netscreen 5GT) Since then I’ve been having some problems with the Internet connection not being quite right. I would say 1 out of every 15 pageviews responds in a timeout. Though a refresh usually does the job. In firefox, this is the message I’m getting:
As for Windows Messenger – it has been having serious problems too.
What could be my problem? Could it be DNS? Every time I try a ping or nslookup it works fine. Could it be the full / half duplex stuff? What else could be causing this? For the most part the Internet works – but just sometimes it does not.
Trust / Untrust Mode
External IPs: A /28 pointing at this firewall. A few MIPs pointing to internal servers on a specific network address.
Internal (192.168.1.1/32) which is set as the trust. We’re using DHCP on this network from 192.168.1.100 to 192.168.1.150.
It’s my suspicion that it’s a NAT setting or something. The computers on the MIPs don’t seem to have any issue. (Thus, the computers that are not public in any way, or that are not doing DNS.) The reason for the IP addresses and MIPs is for simple web hosting, etc.
