assigning WAN ips to servers behind cisco router, and comcast modem
Posted on 2012-12-28
I just signed up with Comcast business class internet and got a block of 13 static IP addresses. I plan on using a separate Cisco RV016 business router that has a lot of functions. I logged into the Cisco router and assigned the first static IP address in the block ending in 50.xx.xx.33 to the router itself. After that I went to the Comcast modem/router and went under the firewall tab and turned on DMZ mode for that IP address, and turned off DHCP mode. I went back to the Cisco router and it seems to be working great. I have a few computers connected and they all have their LAN addresses and I even setup a couple of wireless routers as access points and they are working great as well. The problem is that I have some servers here that I am going to be using as web servers and I need to assign them WAN ip addresses. I went into server 1 and assigned the 2nd static IP in the block to it but it can't see the internet. I can't ping out, or anything. I tried turning off the firewall in the Cisco router, among other things and nothing works. If I unplug the ethernet cord from the Cisco router and plug right into the Comcast modem/router it works perfect and can ping google no problem. I have no idea what to do to fix this. How do I assign my static WAN ip's to my servers using this Cisco router? I may not be understanding this right but I want to create separate VLAN's for each server with a WAN IP address. For example: I want to create VLAN 1 and assign it to port 1 on the front of the Cisco router. I want to plug server 1 into that port and have it setup with a static WAN IP. I want to do that with about 5-6 servers, each with their own VLAN, and WAN IP address. so they are not able to communicate internally here. I have a feeling thats not the way it works but it gives you an idea of what my goals are. Thanks for your help.
