I have Exchange 2003 and a Watchguard firewall
Latest Anti Virus and Spyware locator (Clean server)
If I stop the SMTP service all is well but if it is started my server seems
to be sending the below requests to the firewall till it falls over

If I have a look at the NATDumpTable on the firewall I see about 1000 of the
following entries, after 1000 of these entries the firewall falls over.

What is it? any help would be appreciated
Regards
