_It's still not even reaching the IPSec gateway's eth0 interface_ --
given tcpdump. Never reaches its own interface, much less the LAN
gateway's interfaces to be forwarded on to the phone.
-------------------------------------------------------------------------------------------------------
No port 4500 packet hitting its own interface. Only a keep-alive.
So of course the phone times out and tears down the circuit.
Attached hereto: charon.log and iptables-save. SELinux is Permissive.
I even tried this with # shorewall clear in the IPSec gateway. (stops
the firewall and opens everything wide) No change.
