Ubuntu Server Cannot Route to the Internet
- by ejes
I've been having this problem for weeks now, and I can't seem to figure out the problem.
My server can route the local network and serves it well, however it cannot access the internet. It can't be the router because everything else on this lan can route through the router. I've even switched the ethernet port.
Any help would be appreciated.
I've tried all the usual places, anyway, here are the configs:
