Hi folks,I help out my brother-in-law with his small business network needs as I am able - but have come up against something I can't diagnose. Would be very grateful if fellow geeks could provide suggestions.Set up:Windows 2008 domain - DHCP and DNS on the server.3 computers - all DCHP clients1 Sharp networked printer (MX-2319U) - fixed IP (192.168.1.200), DNS pointing at serverInternet access is via Linksys WAG220G. This unit configured purely as modem - is forwarding to downstream router as DMZ.Router WAS old SnapGear VPN server - but was becoming increasingly temperamental and replacement has been purchased.Router IS new Draytek Vigor 2912. I have tried to configure this device so that it can simply be slotted in as a direct replacement for the SnapGear.With the Draytek in place, all network functionality appears to work as expected - bar one thing. The printer is configured for 'scan to email' and this is broken. From the (web) configuration of the printer, when I run an SMTP connectivity test, I receive a 3332 Error (Connection to SMTP server test failed).Tests performed:From the server (DC), and from a workstation, I can ping and tracert to smtp.gmail.com without issue.Swap back in the older SnapGear unit and scan-to-email works without issue.Thought perhaps new router settings upsetting printer's DNS 'view' - so have used 173.194.72.108 as SMTP server setting in printer config. But still receiving 3332 error.I thought that I wouldn't have to specifically open any outbound ports on the Draytek to allow the port 587 traffic out - but tried this to no avail.Screenshot of printer config screen is here. Would be very grateful for any ideas/suggestions on what I might be able to try to get this working.Thanks in advance.
