[IPIP] is a very simple method of tunneling [IP] packets over an IP connection.
-!
! Kernel Requirements
-You need to have ip over ip routing support compiled in or compiled as a module
+! Kernel Requirements
+You need to have ip over ip routing support compiled in or compiled as a module:
Networking Options -> IP Tunneling (CONFIG_NET_IPIP)
-!
! Userspace Requirements
+! Userspace Requirements
You will also need /sbin/ip (see iproute(8)). This usually comes in a package called iproute (eg [Debian]) or iproute2 depending on your distribution.
-!! Example Network
-There are two machines that we want to create a ip over ip link between for some reason. Lets call them Router A and Router B. These routers are both connected to the internet, you will also need a network to use on the tunnel. In the example below Router A and B have addreses in the same subnet, this is not a requirement, you can create a tunnel to a host on the other side of the internet if you want.
+! Examples
-| Tunnel Network | 192.168.1./24
-| Router A - IP | 192..2.34
-| Router A - Tunnel IF | 192.168.1.1
-| Router B - IP | 192..2.69
-| Router B - Tunnel IF | 192.168.1.254
-
-!! iproute sample setup
-
-You can call your tunnel whatever you like, substitute <name> for something more descriptive in the examples below
-
-!Router A
- ip tunnel add <name> mode ipip remote 192..2.69 local 192..2.34
- ip link set <name> up
- ip addr add 192.168.1.1/24 dev <name>
-
-!Router B
- ip tunnel add <name> mode ipip remote 192..2.34 local 192..2.69
- ip link set <name> up
- ip addr add 192.168.1.254/24 dev <name>
-
-!! Debian sample setup
-
-!Router A
-Edit /etc/network/interfaces
- auto <name>
- iface <name> inet static
- address 192.168.1.1
- netmask 255.255.255.
- network 192.168.1.
- broadcast 192.168.1.255
- pre-up /sbin/ip tunnel add <name> mode ipip remote 192..2.69 local 192..2.34
- post-down /sbin/ip tunnel del <name>
-
-Then execute
- ifup <name>
-
-! Router B
-Edit /etc/network/interfaces
- auto <name>
- iface <name> inet static
- address 192.168.1.254
- netmask 255.255.255.
- network 192.168.1.
- broadcast 192.168.1.255
- pre-up /sbin/ip tunnel add <name> mode ipip remote 192..2.34 local 192..2.69
- post-down /sbin/ip tunnel del <name>
-
-Then execute
- ifup <name>
-
-!!Testing your tunnel
-After you have configured your tunnel via one of the examples above you should be able to ping the remote end
-
-!Router A
- ping 192.168.1.254
-
-!Router B
- ping 192.168.1.1
-
-Both pings should succeed without problems.
-
-!!Using your tunnel
-* You can now use your tunnel - just pretend it's a peice of ethernet between the two computers.
-* Remember the
[MTU
] on the tunnel will be lower than normal because of the extra IP header
.
-* You can setup routing and whatever you like over the tunnel.
-* If you lose your route to the tunnel endpoint, the tunnel will not work either !
