Hi guys, I''m trying to setup an IPIP tunnel between a Cisco router and a firewall running Debian GNU/Linux Sarge with Shorewall 2.0.13. I''ve read and implemented the http://shorewall.net/IPIP.htm document, but I don''t understand why there should be at the same time a "tunnel" and a "tunnels" scrip...

Hello I have /25 addressed on a box (virtual devices on eth0) and I want to tunnel some of these addresses to my home network. One address to my gateway (a.b.c.d, external IP) and one address to my internal network (192.168.0.0/24-style). I will use the tunnels for irc, smtp and surfing. What protocol and which technique is easiest and best to use? One more thing. I don''t want to set up

After carefull reading (LARTC) and experimentation, I am in a dead end... I am using several IPIP tunnels (linux ipip module, IP protocol 4). I''d like to filter packets going through these tunnes to different classes, on the ingress device, based on source and destination IP _INSIDE THE TUNNEL_. First I tried the nexthdr bit. As explained in LARTC, nexthdr jumps to the next header...

Hi, I''ve a gateway host (cali), connected to the Internet via ADSL and a PPTP tunnel (ppp0). I also have a IPIP tunnel to another host over the Internet (mytun), nothing fancy. This is working perfectly. But I want to give more priority to the IPIP packets coming OUT of the PPP (PPTP connection) interface. And I can''t get this to work. Class 2:21 is the one with high priority. FILTERS: filte...

Hello, Looking here http://lartc.org/howto/lartc.tunnel.ip-ip.html It says to load a new_tunnel.o module. There is no such module on 2.6.9, so where would I find up-to-date documentation on ip tunnels in the Linux kernel? Thanks, Mike -- Michael P.

Hello Gurus, I am a small problem with routing and here are the details. Interfaces on my server: * ipsec0 - 172.19.58.94 * tunl0 - 172.19.58.94 * eth0 - 172.19.58.94 Now, the problem is that there is another host 172.19.58.200. All communication to 172.19.58.200 should be through tunl0, and all the data should be secured using IPSec (tunnel mode - because there are more machines on my

...re a way to handle the following? I''m guessing policy routing *might* be the way, but anyway... Two networks, accessible via public addresses -- a /29 on each. Each network, however, has more machines than this, so one also has 192.168.0.0/24 and the other has 192.168.1.0/24. I have an IPIP tunnel between the networks -- 192.168.0.252 -> .253, and routing entries like: 192.168.0.253 * 255.255.255.255 UH 0 0 0 tunl1 192.168.1.0 192.168.0.253 255.255.255.0 UG 0 0 0 tunl1 On the other end, .252 and network 192.168.0.0 via it.

I don''t find the new_tunnel.o module (cf LARTC HowTo). I found Configure.help a bit confusing : CONFIG_NET_IPIP "Saying Y to this option will produce two modules" and then "This driver is also available as a module [...] called ipip.o". Is the tun.o module the ''new'' new_tunnel.o ? I tried anyway to set the tunnel. ipip and tun modules are loaded on A and B. here is the...
