Hi All,
I know something similar to what I am asking has been
posted before but I couldn’t see any responses so here goes again.
We have an IP440 running FW1 (v 4.1) protecting a web
farm. All seems to run perfectly except
for the fact that randomly and sometimes very often the firewall will
apparently stop seeing a particular IP address on the internal network and respond to
all clients with an ICMP type 3 code 1 (Host unreachable message), this can
continue for a few seconds or a few minutes.
During this time the site appears to hang for the users
and they may receive a page cannot be displayed error.
Has anyone seen this behaviour before and if so does
anyone PLEASE know a cure, I am now starting to rip my hair out over this.
Thanks in advance.
Regards
