This may not be strictly kernel related, are you using masquerading?  I have
yet to have a prob with MSN messenger using 2.2 with ipmasq.  But, have you
checked http://ipmasq.cjb.net/

Here's the masq modules I have loaded.
ip_masq_quake           1420   0  (unused)
ip_gre                  6776   0  (unused)
ip_masq_autofw          2556   0  (unused)
ip_masq_portfw          2636   2
ip_masq_mfw             3272   0
ip_masq_ipsec          11812   0  (unused)
ip_masq_pptp            6856   0
ip_masq_irc             1656   0  (unused)
ip_masq_raudio          3064   0
ip_masq_ftp             2680   0

Maybe you should check withe the iptables group at the netfilter home:

Hope that helps.
