IPCop OpenVPN drops connections
location: linuxquestions.com - date: March 27, 2009
I have configured Zerina OpenVPN 0.9.5b on IPCop 1.4.18 firewall. I set it up as per the "how to" guide on the zerina site, and added an internal route to my vpn host server.
On my Windows XP client systems I am running OpenVPN gui V1.0.3.
At first everyhting was OK but after a few days the clients started dropping the connection after about 5 seconds. They now do this reliably every time. There are no errors displayed in either the client or server logs - the client and OpenVPN server both say they are still connected (green). Nothing has been changed on any of the servers, firewall, or clients (no patches or service packs added). Pinging the Green subnet or OpenVPN subnet gateway (e.g.10.10.10.1) works OK for around 5 seconds and then I get "TTL expired in transit"
I rebuilt both IPCop server and client machines and they still have exactly the same problem!
The really anoying thing was that it all worked perfectly to start off with!
Has anyone else any

OpenVPN on IPCop

I have installed Zerina OpenVPN on IPCop to allow me to access our network in the office. However, I can't understand what are these error messages:
CP/UDP: Incoming packet rejected from 192.168.1.1:1194, expected peer address: 126.96.36.199:1194 (allow this incoming source address/port by removing --remote or adding --float)
I have installed OpenVPN on IPCop before but only with two zones (Green and Red). Now I have all the four zones and its not working anymore. Hope someone have encountered this already and can help me on this. Thanks.
IPCop and OpenVPN
location: linuxquestions.com - date: April 12, 2006
Hi! I installed IPCop and OpenVPN to serve us our VPN Gateway. Following the link from
http://thinkhole.org/wp/2006/0/28/ipcop-openvpn-howto, I was able to make it work and I can connect successfully. However, I noticed that I can't connect to all of the workstations within the VPN servers subnet. I tried to ping one using the VPN-IPCop machine and it responded but when I tried it on the remote PC, I won't answer. I also tried using TCP instead of UDP but still not successful. Hope you can help me on this. THanks.
IPCOP Proxy server over OpenVPN
location: linuxquestions.com - date: November 30, 2006
i have an ipcop box running as a firewall, Proxy server and OpenVPN server for outside access. My clients have windows laptops for remote access with a Domain controller from inside. i use the proxy server to monitor internal users access to the internet. i was thinking about creating a group policy to force the users to use the ipcop box as a proxy server when they are travling so i get to monitor internet access for remote users as well. the problem that the proxy server doesn't accept connections from VPN subnet. when i try to browse pages using the proxy over VPN i get access denied error. i wonder if there is a way to modify this behavior. any ideas?
OpenVPN client side automatic start
location: ubuntuforums.com - date: December 23, 2010
I hope that somebody can help me. My problem is with OpenVPN server / client (Ubuntu 10.04) connection.
The problem is that client machine will sit far away, burried in a cabinet out of sight and out of mind. If client machine restart, loose power... etc openvpn connection dies and won't restart.
Im trying to configure on the client side, automatic Openvpn service start and reconnection to the OpenVPN server. I was trying to do that with crontab but without of luck.
Please can someone help me with crontab syntax or maybe provide some other solution?

i spend hours but no solution. I'm connected to my ubuntu server 10.10 with openvpn. I can ping the local ip (192.168.0.15) of the server and its vpn ip (192.168.1.1) but i can't ping other computer on the network behind the server (for exemple 192.168.0.3 or 192.168.0.5).

OpenVPN server directive network/netmask combination is invalid
location: linuxquestions.com - date: November 18, 2008
Ok, I am returning back to the project of setting up an VPN server. I read the How To on the OpenVPN site and followed it virtually step by step. When I try to start the server I get the following error "server directive network/netmask combination is invalid". If the documentation is correct, the configuration should be correct, but yet I get the error and cant figure out why.
The docs recommended using the sample file.
From what I could figure from the documentation, most of the defaults should be sufficient.
As for the environment, its a Red Hat 9 machine, and I installed it from the tar.gz file. The package is installed on the same device as a samba, DNS. DHCP server with a NAT firewall.
