I have a Ubuntu 12.04 machine that has two Ethernet interfaces, both are static.
eth0 is sitting on a network like: xxx.xxx.169.xxx with a 255.255.255.0 mask
It's static address is: xxx.xxx.169.14
eth1 is the gateway to a sub network (also a dhcp server): 192.168.1.1
This network arrangement works fine when there is a direct lan connection from the xxx.xxx.169.14 managed switch.
I'm trying to introduce a client machine (Windows 7) that is also straddling both networks. To do this I've introduced a 4 port dumb switch between the xxx.xxx.169.14 managed switch and the two straddled computers.
The problem:
Windows doesn't have a problem (both machines are the exact same hardware), but Ubuntu get's intermittent connectivity to eventually no connectivity in a short period of time.
When I remove the dumb switch and direct connect the Ubuntu machine it's fine again.
I'm not sure what is going on here, can someone offer some assistance. My only thought (which I haven't tried) is maybe I need a better driver?
Thanks in advance.
