Tunneling lock/hangs/unidirectional
I've setup a lab to test the new tunneling options in the latest

unidirectional.

iptables - Forwarding with port translation thru an OpenVPN tunnel
Perhaps someone with a sharper brain than I can solve this little mystery.
I've Googled until I'm blue in the face, read all TFM's I can find, and
tried several iptables rule combinations but just can't get the following to
work. Here's my challenge:
I have a CentOS-5.3 "main" server with a static public IP address
running Apache, OpenVPN, and a bunch of other

openvpn/shorewall tunnel problem
Dear list,
I am having a problem with openvpn. I have the following arrangement,
running two instances of openvpn on "home fw". I want to protect my
WLAN in back of the home fw and that works fine. I can see "Peer
connection initiated with 192.168.1.3:5000" in daemon.log on homefw.
Nothing gets initiated with officefw, nor can I ping the other end of
the tunnel at officefw.

Waiting until tunnel (ssh -w) is set up before running command
When using VPN tunnelling (-w option), is there a way to know when the
tunnel is actually up? I want to use this in a script that
automatically sets up the tunnel by running ssh -w then running ifup
[1].
The -f option doesn't help because it returns after connecting to the
server but before the tunnel is up. Sleeping for a few seconds does
work, but it just feels too hacky.

Routing all connections through a OpenVPN tunnel
Hi all,
I have set up a working OpenVPN2 connection between my Server and my
gateway at home.
Now I want all traffic to be routed through this VPN connection.
Currently everything is going through eth1 to the internet (to the gateway
of the University which forwards it to the internet :-).
We must use a prox-server and because of this I am not abel to watch the

a strange behavior on a small memory system with tun0
Hello
I am using openssh as vpn on a router with freewrt.org and rsync to sync my local data to a remote server.
Everything works fine for me so far.
The only problem is that the channel-1 (tun0) goes down on the router after 50-200MB transfered via tun0
or after 5-20 hours only with a ping to the server . Channel-0 is still working.
Tcpdump shows that a ping from the router to the server via

tunnel interface names
the fact that ssh insists on tap* and tun* tun/tap-device-names is a real nag and prevents from nice and easy solutions in some cases.
the channel type used for tun/tap forwarding is tun at openssh.com, and it defines the remote tunnel id to be integer.
so from what i understood these packet definitions are static per channel type, so for compatiblity the tun at openssh.com type has to stay,

ICMP time exceeded in-transit sent from wrong interface
Hi,
I''ve got a rather confusing problem.
My linux router box has several internet uplinks of various kinds
(pppoe, ippp, ethernet). These uplinks are used by a tunnel to another
location.
It kinda looks like this:
eth0 - internet uplink
eth1 - LAN
tun0 - tunnel device
ppp0 - another internet uplink
...
Routing is setup with iproute2 in a way that pakets with a source IP
from the LAN

Openvpn routing problem
Hi,
I posted this question yesterday on the Openvpn mailing list, with no
response, figured I will ask here too. I have been using openvpn for
quite a while, no major problems encountered. Now I need to allow the
server to access the lan of the client, and I can not figure out the
routing. This is what I have after the tunnel is brought up:
SERVER (A.A.A.A)

Source address problem
Hello, list
I have a problem with source address selection.
I want all my outgouing mail to go via openvpn tunnel (tun0 device).
The tunnel itself works well:

# ip ro l dev tun0
10.9.0.1 proto kernel scope link src 10.9.0.2
default via 10.9.0.1
At this moment all mail go through tunnel, and everything fine. Now I

Packet vanishes after mangle-prerouting.
Can anyone tell me whether I have a routing problem, or
an openVPN problem, or something else? I''ve stared at this
for so long I think I must be looking in the wrong place!

Machine A has single ethernet card, eth0, 192.168.5.5
