Two NICs, one server
I've clean installed a server with Ubuntu 10.04 LTS. The machine has two NICs and they're both on the same subnet ( bad, I know ). I've gotten around the kernel filtering packets by altering rp_filter as directed to here
On my previous install of this machine (Ubuntu 8.04 LTS), the network setup worked fine without this change in configuration. Now, the network is noticeably slower but functional.
Any idea how to improve this or test what's causing it?
