Hi, all,
I use FW-1 3.0b(SP 8) on HP-UX 10.2, and I meet a strange problam:
The internal user after FW-1 can use http and ICMP service to access
any external IP address.
The problam is: for some web site, the user can ping them, but can't
http them. If I http them before firewall, all is normal.
Then I do bellow test:
1. I telnet the site's port 80, it is active.
2.I use sniffer to capture the package between the firewall and router,
I find that when use http the sites, there are some information:
Source Destination Summary
User's IP Site's IP ICMP: Destination unreachable(Fragmentation
needed an DF)
User's IP Site;s IP Retransmission
Who know why?
Thanks
Tim Lee
