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
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
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)
router is connected to Internet over eth0 - 145.35.162.44 netmask is /21
and network
B:
network 192.168.2.0
netmask 255.255.255.0
router 192.168.2.1 (eth1)
router is connected to Internet over eth0 - 145.35.160.94 netmask is /21
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=/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=/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
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:
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

Here it says ''Network is down''. Try this in between: # ip link set neta up Regards, bert hubert -- PowerDNS Versatile DNS Services Trilab The Technology People ''SYN! .. SYN|ACK! ..
