i've read everything i could find.
that is the latest try:
Remote host:

ifconfig gif0 create tunnel 222.222.22.2 111.111.11.1
ifconfig gif0 inet 222.222.22.2 192.168.0.1 netmask 0xffffff00
setkey -FP
setkey -F
ipsec.conf:
//
spdadd 0.0.0.0/0 192.168.0.0/24 any -P out ipsec
esp/tunnel/222.222.22.2-111.111.11.1/require;
spdadd 192.168.0.0/24 0.0.0.0/0  any -P in ipsec
esp/tunnel/111.111.11.1-222.222.22.2/require;
//
+ racoon with the keys in /usr/local/etc/racoon/psk.txt
setkey -f /etc/ipsec.conf

Local gateway:

ifconfig fxp0 111.111.11.1 netmask 0xffffffff alias
ifconfig gif0 create tunnel 111.111.11.1 222.222.22.2
ifconfig gif0 inet 192.168.0.1 222.222.22.2 netmask 0xffffff00
setkey -FP
setkey -F

ipsec.conf:
//
spdadd  192.168.0.0/24 0.0.0.0/0 any -P out ipsec
esp/tunnel/111.111.11.1-222.222.22.2/require;
spdadd 0.0.0.0/0 192.168.0.0/24 any -P in ipsec
esp/tunnel/222.222.22.2-111.111.11.1/require;
//

+ racoon with the keys in /usr/local/etc/racoon/psk.txt
setkey -f /etc/ipsec.conf
and the connection on the gate drops down.
the error is: /kernel: gif_output: recursively called too many times(2)


i'm wondering what if any troubles because of that RedHat gate with the
masquarade or because of my stupidy.
