So we've been trying KMS for a few days now and we've found that after a while, we have to reset everything to be able to access the mailserver (also on the firewall machine).

Heres the setup....

Billion 7401VGP router -> firewall computer -> DHCP to rest of LAN

The router has one IP to the firewall machine in LAN 1, LAN 2 goes back out to the switch for the rest of the LAN.

KMS is running on the firewall computer and we've set traffic policies up to allow IMAP/SMTP/Webmail access, etc to that machine, which works ok up until about 10-12 hours after initially starting the firewall computer. Then it doesn't accept anymore inbound IMAP/SMTPs. Interestingly, we can RDP into the firewall computer, so I know the portforwarding from the router to the firewall computer is working. I can access KMS on the actual firewall computer, but not on the LAN or from the outside.


I'm wondering whether...

a) the firewall machine is getting bogged down over time with so many connections (we've got about 20+ users on KMS, plus then the DNS and browsing for the LAN, about 10 users)

b) the router can't handle all the requests coming in (although it was fine before we added the firewall into the mix with just port forwarding everything to the mail server)

c) its something else
