Changing Domain IP & DNS servers
We have a Redhat 7 Linux server acting as the gateway and firewall for our office network. We recently upgrade our DSL line to a new higher speed, which means we have new static IP addresses and new DNS servers, and a new DSL Modem/Router with a new gateway address. I'm trying to get our server to route email, host the website, and route internet traffic through the new DSL line. I tried editing the following files:
/etc/sysconfig/network-scripts/ifcfg-eth1 (ifcfg-eth0 is for our internal network, and I don't think it needs to change)
I changed the addresses in those files, but it didn't seem to work. Are there some configuration files that I'm missing that I need to change? Anywhere else that might tell the server what it's IP address is and how to route traffic? Any help would be greatly appreciated.
The current server configuration is doing everything we need to do and working great plugged into the old DSL line. It simply doesn't route traffic when switched to the new line.
