ssh or pinging works on both ends of openvpn
I know its a long time ago, but I am trying to get this working. It sounds like you had a problem with your routing table but I had the same problem the other day I could ssh to the internal IP from a remote network over openVPN but the SIP client would not connect over the openVPN link. I didnt get round to a full debug, I thought I would be lazy and ask first...

To complete: This was bug 1860. I applied the workarounds contain therein and I get a VPN connection with a SIP session running over the N900 SIP stack.

I added the libmissioncontrol-utils with this command

#apt-get install libmissioncontrol-utils

this allows the use of mc-tool commands
then added the lines

script security 2
up /etc/openvpn/nokia.up
down /etc/openvpn/nokia.down

to client.ovpn config file

then created the startup scripts nokia.up

#!/bin/sh
run-standalone.sh /usr/bin/mc-tool update sofiasip/sip/_xxxx string:local-ip-address=$4
run-standalone.sh /usr/bin/mc-tool enable sofiasip/sip/_xxxx
route add -net 192.168.2.0 netmask 255.255.255.0 gw 10.8.0.1 dev tun0

and nokia.down

#!/bin/sh
run-standalone.sh /usr/bin/mc-tool disable sofiasip/sip/_xxxx

then these two scripts must be made executable

#chmod 744 nokia*

thanks to KWEK and others who have been through this before. By the way for completeness the command

$mc-tool list

will give you the sofiasip files that you created when you made the SIP client on the phone, these must be used where I have put _xxxx in the above scripts...

Guys,

I need some help in setting up sip on openvpn. Some details of my network are:

1. Home router: 192.168.1.1
2. Asterisk server and Openvpn server: 192.168.1.152

The server.conf looks like this
Code:
port 1194
proto udp
dev tun
ca privnet/ca.crt
cert privnet/server.crt
key privnet/server.key
dh privnet/dh1024.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1 bypass-dhcp"
keepalive 10 120
comp-lzo
user nobody
group nobody
persist-key
persist-tun
status openvpn-status.log
verb 3
The client.conf on N900 is like this:
Code:
client
script-security 2
up /etc/openvpn/nokia.up
down /etc/openvpn/nokia.down
dev tun
proto udp
remote asterisk.dyndns.org 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert client.crt
key client.key
ns-cert-type server
comp-lzo
verb 3
The nokia.up and nokia.down scripts are as follows:
Code:
nokia.up 

#!/bin/sh
run-standalone.sh /usr/bin/mc-tool update sofiasip/sip/_3101_40asterisk_2edyndns_2eorg0 string:local-ip-address=$4
run-standalone.sh /usr/bin/mc-tool enable sofiasip/sip/_3101_40asterisk_2edyndns_2eor

nokia.down

run-standalone.sh /usr/bin/mc-tool disable sofiasip/sip/_3101_40asterisk_2edyndns_2eorg0
When i do a test through the applet the applet i get the following response:

I also did a
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
on the asterisk/openvpn box.

I am able to ping to 10.8.0.1 from the N900. But the sip connection doesnt go online and i get a network error.

In the sip settings i have defined the server as asterisk.dyndns.org, do i need to change this to 10.8.0.1?

Anybody knows what might be the problem?

Actually i am using the nokia.up and nokia.down scripts from the bugreport but still stuck with sip network error. In the sip settings i have 'discover public address' and 'stun'. i am able to ping to the asterisk server (10.8.0.1) but cannot ping to anything else like yahoo.com from n900. The dns resolving works fine though.
any further ideas?

Does 10.8.0.5 NAT traffic from the N900? It won't go far with a 10.8.0.6 source address.

Bit more information. After the openvpn connection has been made, the client N900 route looks like this:

Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

and the asterisk/openvpn server looks like
Code:
#route -n
