Remote email server not contactable behind router
-
Hello,
Apologies, am a novice at this.
I have a SG-2440, it's on release 2.4.4. About a month ago, I noticed I wasnt able getting my emails from my remote server from MacHighway.com. At first I thought it was due to a bad password that was creating bad logins to their server and thus the IP being blocked. But this is not the case (this time).
But if I VPN to my other location in London where I have another pfsense and subsequent OpenVPN, I can access the emails. And likewise other VPN services and also if I am not at home, I can access my emails. I've been onto MacHighway support and they say after submitting a Traceroute that it could be my ISP (Virgin Media). Been onto their support and they asked me to reset the router which is in modem mode, which I have done. What I did notice, if going directly through the VirginMedia cable modem with my laptop, I can access emails. But as soon as I enable Modem Mode, so that the pfsense box comes into service, then I still cannot access emails.
Havent changed anything on the pfsense box for ages! Any clues where to look? Be a shame to factory reset and go back to configuring it?!
Thanks.

Try connecting to your email on port 587.
My bet is that your ISP is blocking port 25.. Many do.

Hi, thanks for your reply.
Am connecting via SSL and therefore the port is 993 and 465 (in and out).
However, when I reset the VM cable modem, I had my laptop connected to directly via ethernet and when I rebooted it was able to download my emails. Then when set the modem to modem mode and this connect back to my network vi pfsense I wasn’t able to connect to the email server. Making me think that the pfsense is the problem, for whatever reason or other?
Thanks.

Are there any areas I can look at in my pfsense for blockages?

Can you post a screenshot of your LAN firewall rules? Or are they default and untouched??
-
Your very kind Mr Palmer,
Is this normal? I can't remember if thats deafult or added Rules? Thanks?
-
And from this LAN is where you are having the issue?
-
Yes, my internet is served via this
-
My next step would be a packet capture on both LAN and WAN..
/diag_packet_capture.php
See if the traffic is making it to either..

Hi,
Just tried a packet capture (via a remote login as I'm at work), with the IP address of my email server, via the WAN I get packets captured but via the LAN, nothing!

Rules on LAN are fine.
I've the same and can reach the entire planet with these.
So :
Floating rules ?
What is your WAN setup ?
What is your DNS setup ?
What packages are you using ? and if any packages : what happens when you disable them ?
Also : save your config, and goto default, just setup a minimum, aka : your WAN. This will create a situation "all works".Btw : you can't reach your mail server using ports 993 and 465. Your mail server (supplier) has a web mail access - and that works ? Other "sites" that do not work ?

Thanks @gertjan,
By a stroke of fluke, the other week I had my old SG-2220 floating about, which I had issues at my other site and thus replaced some 9months ago, admitteldy, I got myself in a flap and couldnt work out the issues thus just bought a replacement, so the 2220 had been sitting on a shelf and was about to package it up and it had been sold, but just checking it didnt have any personal info on it before despatch where I discovered it was working, firstly on the console so tried the ethernet port and was able to sign in.
So for further laffs and giggles, I swopped it with my current SG-2440 and oddly enough, all my emails we coming in unhindered. Further updated with the current settings from my 2440 and all is good although I think it may be too much for it and it'll overheat, but we'll see.
So could it be a hardware issue? With the SG-2440?? Literally, have all my network settings back and my emails now unhindered!
