Close, but the key isn't pppd, but ipmasq.
See the '-s' option to ipfwadm (or -S for ipchains). From the Debian
'ipmasq' package:
[durin:/etc/ipmasq/rules] 133 % cat Z92timeouts.def
# You should not edit this file. Instead, create a file with the same
# name as this one, but with a .rul extension instead of .def. The
# .rul file will override this one.
#
# However, any changes you make to this file will be preserved.
# Set masqerading timeouts:
# 2 hrs for TCP
# 10 sec for TCP after FIN has been sent
# 160 sec for UDP (important for ICQ users)
