As much As I understand Marius refer o it in his script
"
To get internet traffic from ucsd-gw into the main routing table and ensure reply via
ucsd-gw,
# some mangle rules and one route are needed.
# We will use connection mark "c-44net" and routing mark "44net":
# /ip firewall mangle
# add action=mark-connection chain=prerouting comment="Mark incoming Inet to
AMPR" \
# in-interface=ucsd-gw new-connection-mark=c-44net passthrough=yes
# add action=mark-routing chain=prerouting comment="Mark connection Inet to
AMPR" \
# in-interface=ucsd-gw new-routing-mark=main passthrough=no
# add action=mark-routing chain=prerouting comment="Mark replies AMPR to
Inet" \
# connection-mark=c-44net new-routing-mark=44net passthrough=no
# /ip route
# add comment="Default UCSD reply route" distance=250 gateway=ucsd-gw
routing-mark=44net

You need to use mangle rules in firewall to mark the
incoming packets from the gateway interface and then using route marking route them back
out the way they came.
That is another approach, but you will have to handle outgoing connections as well.
