UDP/NAT timeout?

  • Hi All,

    We have pfSense 2.0BETA4 built on Thu Dec 2 08:32:44.  We have a host inside the firewall downloading from a host on the greater internet, and that download is huge and is thus taking over 12 hours.  However, it appears as if the download is resetting every hour, almost exactly.  The download source noticed this, and they say none of their other downloaders exhibit this behavior.  I was wondering, does pfSense have some kind of UDP and/or NAT connection timeout that periodically resets or something?  The timing of the resets was so regular that I thought I'd ask here to see if it was a known issue, or a feature that I could tweak in some way….?


  • Wild guess: DHCP lease timeout is one hour and you get a new IP address assigned?

    Can you get a timestamp on the apparent resets? Then look through the system logs to see if anything reported correlates with the apparent link resets.

    What kind of resets? The transfer starts again at the beginning? It pauses for a few seconds then … ? ...

    pfSense won't cut off any active connection state. There are timeouts for connections, but they are idle timeouts (no traffic at all that matches the state) – an active connection wouldn't be touched.

    As wallabybob mentioned it may be something on your ISP end if your DHCP lease is that short, or it could also be something on the PC that is doing the actual download.
