Do I gain something setting GPON router in bridge for pfSense ?
I do have a possibility to change a GPON router from NAT mode to bridge mode, then pfSense to handle NAT and so on. Currently i'm doing double NAT (first on GPON device - this one has full port forwarding downstream) and second NAT on pfSense side.
Will there be a notable performance improvement? (I do have almost symmetric 1Gbit/s link)
Or what are general pros and cons if making that happen?
Thanks for your opinion.
Yes you avoid a double NAT.
Some IP traffic has the IP address in two locations in the packet, NAT will only change the header.
