I use a 9k mtu on my 10gb network @ home -- only exists between my
desktop & my server where it can be worthwhile.
Bridged to that NW is a 1gb, 1.5k mtu network use for my home IOT
(Internet of Things) This works for administrative traffic, for the most
part, but in gaining
some new 'things', some wish to talk to a media/file server on the
higher BW net.
Someone referred me to possibly using tcp mss clamping, though they were
it in the context of a VPN tunnel which I'm not using.
I'm wondering if it is
as simple as installing routes with mtu clamping so hosts
wanting(needing) to goto
a smaller mtu would take the appropriate network and talk with smaller
Seems there maybe something missing there since some traffic can be
ip-level w/no tcp
in play (ex: dns). Doesn't seem that would really work too well...
Has anyone had any experience w/this type of setup?
