what is orbi's tcp session timeout value?

ive got att uverse internet dsl.  i suspect the pace modem does a nat'd dmz mode.  it's set for 86400 seconds.  i suspect with the two being different is clogging up (dont know the offical term) the pace modem.  something like devices connected to the orbi is generating more sessions than the pace modem can handle; which appears to be 8112 sessions.  its easier for me to change value in the pace modem to match orbi.  incidentally, ive had the pace modem set for 1800 seconds for the last five days or so and no internet service disruptions since.  meaning no complaints from wife and kid for five days....ive made the internet great again.

can you dig up the value for udp? might as well set them to matching values.
