Hi,
I have a problem with GRE tunneling. I read  Advanced-Routing HOWTO
about this and I did all as is written in this documentation. Even the
same example is here which I need for my project.
I want create (by means of GRE tunneling or IP in IP tunneling) virtual
private network VPN - in first phase without IPsec in other phase with
IPsec.
I have two local networks distant apart with two routers. Both routers
have registered IP addresses (I have only two registered IP addresses =
and many
computers in local netwoks which I connected to Internet); first router =
connects
one local network to Internet and second router connects other local =
network=20
to Internet. Computers in both networks have the access to Internet over
routers because I configured IP-Masquerade. Now I want solve the access =
of=20
computer from my first local network to computers from my second local =
network.

So I have network
A:
      network 192.168.1.0
      netmask 255.255.255.0
      router  192.168.1.1 (eth1)
    =20
router is connected to Internet over eth0 - 145.35.162.44 netmask is /21

and network=20
B:
      network 192.168.2.0
      netmask 255.255.255.0
      router  192.168.2.1 (eth1)
    =20
router is connected to Internet over eth0 - 145.35.160.94 netmask is /21 =
          =20

I wrote this two scripts (I use RedHat 6.1 on both routers with kernel =
2.2.12)

file rc.ipip on router A

#!/bin/sh
PATH=3D/sbin:/usr/sbin
echo installing modul...
modprobe ip_gre
echo setting tunl0...
ip tunnel add neta mode gre remote 145.35.160.94 local 145.35.162.44 ttl =
255
echo adding network ariel2...
ip addr add 192.168.1.1 dev neta
ip route add 192.168.2.0/24 dev neta

in file rc.local
.
.
.
/etc/rc.d/rc.ipip

file rc.ipip on router B

#!/bin/sh
PATH=3D/sbin:/usr/sbin
echo installing modul...
modprobe ip_gre
echo setting tunl0...
ip tunnel add netb mode gre remote 145.35.162.44 local 145.35.160.94 ttl =
255=20
echo adding nework ariel...
ip addr add 192.168.2.1 dev netb
ip route add 192.168.1.0/24 dev netb

in file rc.local
.
.
.
/etc/rc.d/rc.ipip

...it's so easy...but
When I start these scripts the error come:=20
RTNETLINK answers: Networking is out of work
Where did I make mistake?

---------------------------------------------
And second thing...
When I tried to take in work IP in IP tunneling I didn't know where to =
find
modul new_tunnel because this modul is'n in my distribution of RedHat. I =
haven't
problem with modul ipip.

I would be very happy if somebody could help me.
thanks,
     Vilem Musil

....sorry for my english
