Setup of Firewalla Purple using DHCP Mode
Hello,
I read a number of posts about using Firewalla purple in DHCP mode but can't seem to find an answer to my question. I am unable to use Firewalla in router mode or transparent bridge mode so I am using it in DHCP mode. Simple mode does not seem to work really well with my Verizon G3100 router. The problem I have having is with port forwarding. On my router I have port forwarding setup for OpenVPN to Firewalla and a port open for my Plex this stopped working when I switched to DHCP mode, in Simple Mode it worked. I have turned on the DMZ Host function in my router and pointed it to my Firewalla but when scanning my Firewalla from Sheilds Up I see the ports are not stealth and port 22 and 52 are open to the internet. I guess my question is in DHCP mode how do I get port forwarding to work with the double NAT created by DHCP Mode. Hope my question makes sense.
v/r,
Chris

DHCP mode, see this https://help.firewalla.com/hc/en-us/articles/360017789393-Create-Port-Forwarding-on-Red-Blue-Blue-Plus
Any reason why your purple can't run in router mode? I do know we have many customers are using the G3100 with firewalla purple in router mode. see examples here https://help.firewalla.com/hc/en-us/articles/4411167832851-Firewalla-Router-Mode-Configuration-Guides

I was told because we have Fios TV and the boxes connect to the router I am using has to be connected directly to the internet with no firewall between it so it can get updates. I am not sure how true it is but that's what I was told and concerned that if I do put my Purple in router mode there may be problems with the TV boxes. Thank you for the articles, I will look through them.

I would still have to deal with a double NAT correct? The G3100 I have is both a firewall and a router. There is no option to put it in AP Mode like with the Orbi. On the brighter side OpenVPN seems to be working now for some reason so I can get to my Plex using OpenVPN. That seems to be the best solution to all this. DHCP mode seems to work far better than Simple for my specific use case.

I forgot to mention that I routinely test my Firewalla and FW status by going to GRC | ShieldsUP! — Internet Vulnerability Profiling and I test the add blocker in Firewalla with Can You Block It ? - A Simple Ad Block Tester.

Interesting article. So far in DHCP mode I have not seen any ill effects for the Fios TV and my through put seems ok, we have two extenders as well. As long as I can use OpenVPN to connect to Plex I think I am good. That's the only thing I would want to get to from outside my network. I very much appreciate the time and help with this and the information!
