Hi All,
I have replaced my old SME 5 server (which worked without a hiccup in the following config) with a new and improved SME7RC3 one and most things are now working fine. I run it in Server/Gateway mode but behind a Draytek 2800 Router/Firewall. The Draytek has several ports forwarded to the "external" in the server to provide Webmail etc from the Internet. Sometimes this works OK (albeit a bit slower than the SME 5 under the same config) but other times it will timeout before even asking the Certificate questions.
Accessing anything from the LAN on port 443 is just fine and I am also able to access Webmail and Server Manager via a VPN (Draytek is the endpoint) with no problems.
Also (and I am not able to prove this fully) we believe that not all email is getting through. Any time I send tests from several outside accounts, they get in almost immediately. However, others have reported emails not being delivered and being delivered slowly resulting in complaints from outside contacts. Our email is routed via a company who stores it if our server is down for any reason and they have reported many instances of their server not being able to reach port 25.
About now, if I were reading this, I would be saying "that has to be a router issue" but I have engaged Draytek who have examined the router and advised that port 443 is being forwarded OK but is not being responded to. They asked me to check is my default gateway on the server was correct which it is (thankfully, so not too much of a red face!). Also, remember that the old server worked fine under this config.
I have also replaced the external NIC (another Realtek 10/100/1000) in the hope that this was the problem but no change.
Does anyone have any ideas about this one and have there been any communication issues reported between Draytek routers and SME servers?
