SMTP/FTP connections fail after 5 minutes
-
Hello All,
Have been having an issue with a Pfsense box (version 2.1.5), have set up NAT port forwarding for SMTP and FTP which works great for about 5 minutes.
Then after that all external SMTP and FTP traffic either gets blocked or dropped and can longer connect to FTP or receive emails (all incoming connections initialised from outside the network), but can still browse the internet. Should also mention we have a high volume of SMTP traffic incoming don't know if this would affect it though.
Does anyone have any ideas what could be causing this? any/all help is greatly appreciated.

Any packages like Snort running?
-
No packages running just vanilla Pfsense.
-
Any chance of upgrading it to something a little more current so that you're not chasing old bugs?
