gateway monitoring issue

  • Hi
    I configured pfsense 2.4.4-RELEASE-p1 for dual wan scenario,

    i have two dsl modems and dsl gateway ip set for pfsense monitor ip for each pfsense gateway.

    but when there is a download going on one gateway ,that gateway goes down because of network latency!
    if i set the monitor ip to dsl modem itself, monitoring service cannot detect internet connectivity, and if i set monitoring ip to dsl gateway or some public dns or ip then it goes down because of latnecy,

    is there a fix to this or better solution to monitor internet connectivity?

    With very high bufferbloat you will have other problems then only gw monitoring issue as well.
    You can try the CoDel Scheduler, @jimp did a very short but good topic for CoDel, check it out here:

  • I use two OpenDNS IP addresses as gateway monitoring. Originally I tried the Modem IP and Google DNS but in both cases the monitoring was not great. With opendns it seems to work much better.

    OpenDNS server addresses, and for GW 1 & 2 respectively.

  • this is not fixed my problem , pfsense multi-wan not working well , switching between wan connections and lots of latency and packet loss are more when in single wan mode , when using each wan in a single wan mode there are much less latency and packet loss and down time.
    i tried a lots of configurations with no success and everybody has complaints about internet down time after multi wan enabled.
