forward a different port for each cam on your router :
router port 81 => Local-IP-cam-1 port 80
router port 82 => Local-IP-cam-2 port 80
then in your html :
<img src=http://PublicDNSName:81
” width=”640” height=”420”/>
<img src=http://PublicDNSName:82
” width=”640” height=”420”/>
Option 2:
forward router port 80 to an Apache2, located on a computer/server/pi
configure Apache2 for Reverse Proxy several locations to each of your cam :
<VirtualHost *:80>
...
...
</VirtualHost>
and in the html :
<img src=http://PublicDNSName/cam1
” width=”640” height=”420”/>
<img src=http://PublicDNSName/cam2
” width=”640” height=”420”/>
