what version of iptables are you running?

$ sudo iptables --version
iptables v1.4.21

can you also note which iptables modules you have loaded?

$ sudo lsmod | grep -E -e"^nf_|^ipt|^ip6|^xt_|^ip_|^ebt|^x_" | cut -f 1 -d " "
ipt_MASQUERADE
iptable_nat
nf_nat_ipv4
nf_nat
nf_conntrack_ipv4
nf_defrag_ipv4
xt_conntrack
nf_conntrack
xt_CHECKSUM
iptable_mangle
ipt_REJECT
xt_tcpudp
ip6table_filter
ip6_tables
iptable_filter
ip_tables
ebtable_nat
ebtables
x_tables


i think that covers all the iptables ones... at least the ones i recognize on
this system... on one of my firewalls, we have these...

$ iptables --version; lsmod | grep -E -e"^nf_|^ipt|^ip6|^xt_|^ip_|^ebt|^x_" |
cut -f 1 -d " "
iptables v1.4.4
ipt_set
ip_set_iphash
ip_set
nf_nat_pptp
nf_nat_proto_gre
nf_conntrack_pptp
nf_conntrack_proto_gre
nf_nat_ftp
nf_conntrack_ftp
nf_nat_irc
nf_conntrack_irc
xt_CONNMARK
xt_MARK
xt_mac
xt_length
xt_tcpudp
xt_mark
xt_dscp
xt_ipp2p
xt_connmark
xt_multiport
xt_state
xt_DSCP
xt_CLASSIFY
xt_ACCOUNT
ipt_MASQUERADE
ipt_REDIRECT
ipt_REJECT
ipt_LOG
iptable_mangle
iptable_nat
nf_nat
nf_conntrack_ipv4
nf_conntrack
nf_defrag_ipv4
