But not very much - there is the static table thats affected by the limit
in ip_masq.h so thats allocated at startup, and one struct per connection.
That struct is not too fat - I'd guess 64 to 128 bytes (not sure what the
alloc overhead is).
Frankly memory is not a problem for masq *unless* you are running
squid/bind/mail etc on your gateway as well and they are snarfing all the
RAM.
