Will look into fwbuilder but so far was planning to go with a server distro (no GUI) and was hoping to get by using iptables directly for NAT. With regards to bufferbloat, I had run the DSL reports ...

What is a good router that supports the open source pfsense? I don't care for wifi but it needs to have gigabit speed support.

Moving to OPNsense was worth the extra effort ...
