it not necessary at all!

set your default router in rc.conf (ask your University admin about its IP)

you just look at "sysctl -a net.inet.ip.forwarding"
if it equals "0" then "sysctl -w net.inet.ip.forwarding=1"
(in rc.conf this variable is set by gateway_enable="YES")

then you need a natd
just "touch /etc/natd.conf" and edit it so that it contained something like

log yes
#log_denied yes
port 8668
use_sockets yes
same_ports yes
unregistered_only yes
alias_address ???.???.???.??? #your PUBLIC IP
###
#EOF
###


run natd "/sbin/natd -f /etc/natd.conf &"

edit /etc/rc.firewall to contain approximately the following

#!/bin/sh
/bin/echo -n "Firewall... "

(this is a fragment of my ip.firewall which is too long to quote here...)


and execute the file (chmod 500 rc.firewall, you know, first... ;))

it should work. if not, ufff... than you will have to rebuild the FBSD
kernel with IPDIVERT, IPFIREWALL and things, and things, and things... and
repeat the said above...

I envy you if you're gonna do the kernel rebuid for the first time :) it's a
fascinating, absorbing and captivating procedure like playing chess with a
very strong chessplayer :)
