It's still more than 1-2 orders of magnitude faster than the original Pi. And probably 2-5x faster than a Pi2.
That said you could get a $2 USB Ethernet adapter on ebay ... and plug it into the pi and experiment with that. The Pi will probably show your internet down since it's peripherals all hang off it's overloaded USB bus.
The P4 ought to handle it with ease... as far as that goes lots of people have used much slower machines for routers/firewalls. Rather than using wireshark which is a rather heavy handed but comprehensive solution, you just do as suggested here with dnsmasq
How to log all my DNS queries? - Unix & Linux Stack Exchange
And filter the log for dnsmasq output.... just about as good as wireshark and probably more performant than running without the system as now your dns queries are cached by a local machine. The TCPDUMP answer there is also good.
If you get it working on the P4 getting a mini PC is probably a decent idea... as the power savings alone will pay for itself. A P4 computer costs between $100-300 a year to leave running vs the mini PC costing about 10 bucks a year.

desproxy-dns
desproxy-dns(1) User Commands desproxy-dns(1)
NAME
desproxy-dns - DNS for dynamic connections
SYNOPSIS
desproxy-dns dns_server proxy_host proxy_port
OPTIONS
None
DESCRIPTION
If you have direct DNS access then you don't need to do anything else. You know you have direct DNS access if you can resolve host names
to IP addresses.
NOTE: as desproxy-dns listens in port 53 (which is less than 1024) you may need administrator privileges to exec desproxy-dns (in fact if
you are running UN*X, you actually have to run desproxy-dns as root).
OK, so you have a dns server accessible now. But your computer doesn't know anything about that. You must configure your network
accordingly (again, need to be root in UN*X).
Edit /etc/resolv.conf and add the line "nameserver 127.0.0.1". You don't have to restart anything. Just test ping and see if it works.
ENVIRONMENT
None.
FILES
None.
SEE ALSO
dnsproxy(1), ping(1)
