hi,

I have gateway system, which is receiving a lot of packets. Due to which, it might be dropping some packets.

I assume you are getting "Neighbour Table Overflow" messages.

Is there a way to increase the neighbour table size? (some value in /proc I should look for)

Try increasing /proc/sys/net/ipv4/default/gc_thresh[1..3] values.

Would sharing the load among other network cards /using subnets help?

Yes, since, IIRC, neighbour information is stored per device.
