I have blocked most outbound ports on my firewall except for the ones
we use and as a result I cannot recieve email. I am running a Winnt
network with Exchange 5.5 and a Watchguard SOHO firewall. After
blocking outbound ports I view the SOHO event log to see successfull
inbound port 25 traffic but immediately follow an accepted port 25
packet I see a rejected outbound packet from my exchange server. The
outbound port in question seems to be random based on the source IP.
Can anyone there help me find a registry hack for exchange to specify
these outbound port ACK's?
