Thank you in advance for any assistance/posts that you may provide.
I currently have ATT Uverse internet with 5 static IPs assigned. My IPs are XX.XXX.XXX.233 - 237. From what I have gathered on reading other posts is that Uverse works quite differently with regards to how I can use my static IPs. Like most business class routers, I believe that Untangle can connect to the modem via the external NIC and then assign aliases and get all of the static IPs.
Given that I am a residental cutomer, I have a 2Wire router that will only assign 1 static ip per MAC address. I am guessing that I cant use my static IPs without adding more NICs to my Untnagle server. So I added 2 NICs to my untangle server hoping that I could use a couple of my static IPs. My plan with the 2 extra NICs are to assign one to my mail server and the other to my web server. My question is how to set that up?
Right now my external NIC is set up with one of the static IPs, XXX.XXX.XXX.233. It has a netmask of 255.255.255.248 (29) with the gateway set at XXX.XXX.XXX.238, this is what it is as Uvserse assigns more than just 5 static IPs, but only the 5 are useable. All of the Xs are the same numbers. All works great. I have set my Uverse router to DMZ plus mode, wich sends the external NIC right to the internet without a firewall. I have untangle set up in router mode without DHCP as I have a domain controller taking care of DNS and DHCP.
My internal NIC is set static to 10.2.100.1 /255.255.255.0 (24).
Now I have a DMZ and eth03 NIC ready to be used. I am able to get a static IP from my Uverse router because each of these NICs have a MAC address. I have assigned XXX.XXX.XXX.234 to the DMZ NIC for now.
What should I set the DMX NIC to be? static, dynamic, or bridge. I should note that the Uverse router also makes me us DHCP for getting the static ip. I have set up the DMZ to be dynamic and it seems to connect okay, but what
What I really want to do is make all traffic on XXX.XXX.XXX.234 go to 10.2.100.26 on my internal network (mailserver). What is the best way to achieve this?
Thank you for any help, I hope there is enough information here.
