Hi all,

Been fiddling with the home LAN today - I've got a WatchGaurd firewall which has been kicking around for a few months and finally got around to installing it today.

I've got a NAS device on the home LAN which sends out notifications when new users are configured / error reports that kinda thing.

It was configured before the firewall was put in so I know it can send the notices ok.

However - since the Watchguard was install (a few hours ago) the NAS no longer sends the notices.

The only wierd thing is that my SMTP server uses port 26.

The smtp server and port is configured along with authentication details however the device reports:

Failed to send email (Failed to resolve host address)

I can telnet to the smtp server on port 26 and get authenticated.

Any ideas?
