How would one modify the following line in iptables file (debian)?

ACCEPT     all  --  XXX.XXX.XX.X         anywhere            PHYSDEV match --physdev-in vif3.1

TO

ACCEPT     all  --  YYY.YYY.YY.Y         anywhere            PHYSDEV match --physdev-in vif3.1

I looked up the https://wiki.debian.org/iptables and I'm having hard time figuring out how to exactly do this modification. Can it be done using one command, or there is a way to temporally "extract" the iptables file and modify it using nano or vi, and put it back in place?
