Multiple Wan IP to multiple servers using same ports
-
I thought I would post this for anyone else that has tried to do the same thing with 2.1 and fought it.
What I needed to do was forward traffic on the same port to different internal addresses. I have 2 wan ips going to 2 servers both using port 80
Ex.
77.33.44.55:80 to 192.168.0.5:80
77.33.44.56:80 to 192.168.0.6:80To accomplish this I did the following:
My first IP was already configured as my Primary Wan connection so from there,1. set up a virtual IP by going to Firewall> Virtual IPs the click the add button, select the IP Alias radio button, set the ipaddress as 77.33.44.56/32, named it and hit save.
2. Create 1:1 nat as follows
Firewall>NAT click the 1:1 tab, click the new entry button then
Interface > WAN
External Subnet IP> 77.33.44.56
Internal IP> 192.168.0.6
Destination> any
Description> second wanClick Save then click apply
3. set up port forwarding for each connection setting the destination address as the external wan address as follows:
For the first wan address that is also my primary wan:
Interface > WAN
Protocol > TCP
Source > any
Destination> type is single host address is 77.33.44.55
Destination port range> HTTP for both
Redirect target IP> 192.168.0.5
Redirect target port> HTTP
Description> nat forward 1click save, then click apply
–For the second wan address:
Interface > WAN
Protocol > TCP
Source > any
Destination> type 77.33.44.56 (second wan)
Destination port range> HTTP for both
Redirect target IP> 192.168.0.6
Redirect target port> HTTP
Description> nat forward 2click save then click apply
The key on this was that after creating my 1:1 nat rule, it then showed up as a destination type in my port forwarding rules so what my port forwarding rules are doing is this:
if the request @ port 80 has an external destination of 77.33.44.55 then forward to 192.168.0.5
if the request @ port 80 has an external destination of 77.33.44.56 then forward to 192.168.0.6There may be a different or better way to accomplish this, but this method seems to work pretty smooth for me, and hopefully it can save someone a few hours of cursing to get to the same end goal
