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.

dnsspoof
DNSSPOOF(8) System Manager's Manual DNSSPOOF(8)
NAME
dnsspoof - forge replies to DNS address / pointer queries
SYNOPSIS
dnsspoof [-i interface] [-f hostsfile] [expression]
DESCRIPTION
dnsspoof forges replies to arbitrary DNS address / pointer queries on the LAN. This is useful in bypassing hostname-based access controls,
or in implementing a variety of man-in-the-middle attacks.
OPTIONS
-i interface
Specify the interface to use.
-f hostsfile
Specify the pathname of a file in hosts(5) format. Only one hostname allowed per line (no aliases), although hostnames may contain
wildcards (such as *.doubleclick.net).
expression
Specify a tcpdump(8) filter expression to select traffic to sniff.
If no hostsfile is specified, replies will be forged for all address queries on the LAN with an answer of the local machine's IP address.
FILES
/usr/share/dsniff/dnsspoof.hosts
Sample hosts file.
SEE ALSO
dsniff(8), hosts(5)
