I have a problem. I installed apache2 on my ARM-PC - and opened port 80. In my network i have 2 routers - first which is property of internet provider - i can only set here a DMZ device, and second - connected to first - with OpenWRT which handles all traffic between my computers and internet. In both routers i have different IP addresation - in first - 192.168.1.xxx - second 192.168.3.xxx
In first router I set a second router's IP as a DMZ device. I tried to make openwrt luci panel accesible from internet - so i made port forwarding of itself router - to strange port 5044 - and It works(i can access it from my public address). But when i try to forward port of another device in my network, with running apache server - I can't access it from internet...
The strangest thing is that - when i made port forward of second (Openwrt)router from it's config - i cant access it from network of first router on specified port - from internet - I can. But when I forward port of server - I can access it on first routers network, but not from the internet 
. Had somebody dealt with this problem before?
