So is there any downsides to setting keep alive to a short period?

I want to set timeout to even shorter value of 30 seconds.
My problem is that my internet provider's network appliances are "too
smart" and they close idle connections real fast. At least thats what
I suspect.

If anyone else know anything about it please respond. Thank you.
