Exactly the right place to ask, don't worry.
What you're probably missing is conntrack, which moved to
Networking ->
Networking options ->
Network packet filtering framework (Netfilter) ->
Core Netfilter Configuration
There, enable "Netfilter connection tracking support"
(CONFIG_NF_CONNTRACK_ENABLED) and "Netfilter Xtables support"
(CONFIG_NETFILTER_XTABLES).
Then, one menu up and into "IP: Netfilter Configuration",
enable
IPv4 connection tracking support (CONFIG_NF_CONNTRACK_IPV4)
IP tables support (CONFIG_IP_NF_IPTABLES)
Full NAT (CONFIG_NF_NAT)
and optionally MASQUERADE / REDIRECT.
I understand those config options were moved because they are
actually not IPv4 specific ("iptables") but more general,
IPv4 / IPv6 / ARP ("xtables").
The binary for setting the rules is still called "iptables", though.
