Firewall with no NAT - Proper Connections / Addressing
Smack2k last edited by
I am interested in setting up a pfsense firewall on my home network instead of the currently in use Verizon FIOS Quantum Gateway firewall I am using. Due to where the Verizon box is installed in my garage and other issues, I am unable to use the Ethernet ONT and have to use the coax connection into my Verizon router. Currently I have several machines connected directly to the Verizon Router and others connected to a switch coming off the router.
So my questions are:
- Where would I place the pfsense fw in this config? I am assuming between the Verizon router and the home network devices. I Could get another switch and hook up the devices that are directly connected to the Verizon Router currently.
- Is there a way to setup the firewall without NAT as NAT is already taking place at the router when information goes out.
- If I can set it up without NAT, how would I connect it up physically? For the network in and network out, how would I configure it?
- How would the devices get IP Addresses if the FW is in between the router and devices?
- Would the TV boxes be affected from getting program guides / DVR / etc? They get their connection / IP / config from the Verizon Router currently.
- Same question for wireless when it comes to getting IPs?
Or is this just not something I can do properly with current setup?
Looking for advice / options
Thanks ahead of time for any info you can give....
You could set up pfsense as a downstream router without nat - IF!!! you have access into the verizon router to setup the transit network to the downstream router/firewall.
I doubt they allow such things though..
Your best bet is to just double nat, put everything behind pfsense. Aso to stuff that gets TV signal - you could put on the transit network between verizon and your router.
