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
