nope, just plain netfilter/iptables. Specificly (lsmod output) :

ipt_TOS 880 8 (autoclean)
ipt_MASQUERADE 1312 4 (autoclean)
ipt_state 576 7 (autoclean)
ipt_REJECT 2816 7 (autoclean)
ipt_LOG 3408 24 (autoclean)
ipt_limit 1008 26 (autoclean)
ip_nat_ftp 3184 0 (unused)
ip_conntrack_ftp 3536 0 [ip_nat_ftp]
iptable_mangle 1712 0 (autoclean) (unused)
iptable_nat 14448 1 (autoclean) [ipt_MASQUERADE
ip_nat_ftp]
ip_conntrack 15056 5 (autoclean) [ipt_MASQUERADE ipt_state
ip_nat_ftp ip_conntrack_ftp iptable_nat]
iptable_filter 1680 0 (autoclean) (unused)
ip_tables 11392 11 [ipt_TOS ipt_MASQUERADE ipt_state
ipt_REJECT ipt_LOG ipt_limit iptable_mangle iptable_nat iptable_filter]

I've also attached the output of 'iptables -L -n' so u can get an idea
of what its running.
