Ideally, you'd fix your broken network infrastructure. However,
if you can't ...

... that's exactly backwards about how to work around it. You need
to *reduce* the interval at which keepalives are sent. Try setting
tcp_keepalives_idle to 10min or so. (At least on my Linux box,
it seems to default to 7200s = 2 hours, so that it's no surprise that a
router that drops connections after 30 minutes would cause problems.)
