Public bug reported:
I have a Juniper firewall (SSG-5) that does ISAKMP with NAT behind my
linux server. This works with the following iptables rule under
linux-2.6.32.-24:
iptables -t nat -A POSTROUTING -s <my private network> -o eth1 -j SNAT
--to <my public static IP>
Under linux-2.6.32-25, the NAT rule shows up in the listing of "iptables
-t nat -nvL", but it fails to do a source translation. My private
network, an RFC 1918 non-routable network, simply leaks out my public
interface (confirmed by a tshark trace) and my ISP simply drops the
packets.
