Post by: jvels on October 19, 2006, 07:13:48 PM

Hello

I have install the OpenVPN bridge from Firewall-Services.

But i get this error:
Tue Oct 17 21:04:03 2006 client/10.0.0.100:33496 MULTI: bad source address from client 10.0.0.10, packet dropped

Code: [Select]


[root@velsserver openvpn]# route -n

Well, your route seems to be good, can you post your /etc/openvpn/server.conf ?
maybe it can help me debugging this.

I  use the bridge openvpn from firewallservice.com with webpanel

The error is here

Code: [Select]

client-to-client
max-clients 20comp-lzo

it should be

Code: [Select]

client-to-client
max-clients 20
comp-lzo

This error comes from a template, I forgot to update the archive. To fix it, edit the file /etc/e-smith/templates/etc/openvpn/server.conf/80clients

and change the line:

Code: [Select]


$OUT .= "max-clients $maxClient";

by this one:

Code: [Select]


$OUT .= "max-clients $maxClient\n";

then expand the template

Code: [Select]

expand-template /etc/openvpn/server.conf

And restart the service

Code: [Select]

/etc/init.d/openvpn restart

I think it should be ok then, I use it on several servers. I'll update the tar archive. For the new version with much more features you'll have to wait more than I thought as I'm working on the integration of trixbox (that you can already test).

Hopes this will fix the pb.
Cheers, daniel
