If you take just my Web server as an example, it must be assigned a static IP, then a rout to the internet via one of my LAN ports need to be established.
I am doing incorrectly because I don't know what I'm doing, and trying to get information that will help me understand so I can do it correctly.
I am using the GUI!!!!
I'm confused why you asked for steps, then persist on undertaking other steps not suggested by anyone in the thread.
You're confused... Persist? I have taken all information from this thread and implemented them. However, if you would read the thread from the perspective of someone who doesn't have your knowledge you would see how confusing this is.
Can you please be a little more choice-full in your language, you are coming over as angry and impatient?
I really appreciate your input and its frustrating enough without having to explain my misunderstandings.
Each of the servers has its own firewall
I need to configure 3 of the physical ports, located on the back of my Router, to connect to the internet so that traffic going to, and from, the assigned static IP addresses can freely access the internet.
I do in a classroom, not for advanced router software which assumes a basic understanding in networking (or Wiki reading) itself. Your questions (if any) seem more like "why are you saying do this"...but you failed to actually ask me that...others complain I'm "dumbing down for them". You can never win online.
Also, I'm not sure why you edited the quote as-written in my profile to insert the word "in" - in academic circles, that's a red flag "[academic] dishonesty" may follow...this is especially true in an instance such as this, where the edit clearly makes the proceeding sentence nonsensical; and limits the context of the one actually quoted.
Overall I see three different approaches.
a) Layer3 DNAT: Add all public IPs available to user to OpenWrt WAN interface then use DNAT to provide access to internal servers. My posts #57 and #59 detailed how to do this. Read them again word by word carefully and it should be clear. Read the reference links as well. SSH access to router is required as I don't know how to use uci or /etc/config/network to implement those 'ip add add' commands.
b) Layer2 Vlan: configure one public IP to each name server and put ISP, OpenWrt and name servers in the same vlan(vlan2 in this case).
c) proxy arp + Layer3 routing: Similar to b) but the public IP will be configured as sort of loopback on name server. I won't go into detail here.
