i need some advice.
I have two OpenWRT routers.
One is connected to modem and gets public IP.
To that router is connected powerline adapter.
To powerline adapter there is connected one PC and second OpenWRT router.
What i would like to achieve is create DMZ to that second router.
I know that there are at least two types of DMZ I can create. One by VLAN and one simply by setting up port forwarding.
My questions are:
If i will create just port forwarding (for all ports) to that second router (by its IP) is there any security implications that may expose network of the first router?
In my case is that the proper way of creating DMZ?
Creating DMZ in my case, will it limit in any way internet access (not working services etc.) or people using first router will have no implications at all?
Thank you for any replies.
