Linux client problem

Post by SteveM » Tue Jan 11, 2011 4:01 am

Hi All,

I have a problem and I think I am missing something very simple.

I lost my VPN server with no backups and had to reinstall OpenVPN on a different box. Now Windows 7/Vista clients connect and work perfectly. Linux (Centos and Ubuntu) clients can connect but I can't even ping the vpn server from the client and vice versa.

My server config:

local 203.21.3.208
port 1194
proto tcp
dev tun
ca ca.crt
cert server.crt
key server.key # This file should be kept secret
dh dh1024.pem
server 10.10.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "route 203.21.3.0 255.255.255.0"
keepalive 10 120
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 4
float


My client config:

client
dev tun
proto tcp
remote 203.21.3.208 1194
resolv-retry infinite
persist-key
persist-tun
ca ca.crt
cert devel.crt
key devel.key
comp-lzo
verb 4


I hope someone can show me what I am doing wrong! I feel that when I can successfully ping 10.10.0.1 it'll be fine!


Regards,
Steve

Hello, Steve.

Post your client and server log corresponding to a failed connection and I'll see what I can do.

did you allow then tun device in your firewall? see the FIREWALLS section of the manual... it has some iptables specific commands you might need

I basically disabled firewallls for testing both on the server and the client.

All I am trying to acheive now is to be able to ping 10.10.0.1 which is the VPN server tun0.

try this

Code: Select all

iptables -A INPUT -i tun+ -j ACCEPT
on your client

We fixed the problem by adding

push "route remote_host 255.255.255.255 net_gateway"

in the server config.

I don't have any explanation for that so if anyone knows why this works better I'd really like to hear.

We also changed to udp but that was just because most clients had that in their configs in the past before the old server died.

o lol right
this was needed because you did this:
push "route 203.21.3.0 255.255.255.0"
which told the routing table of the clients to route 203.21.3.0/24 over the vpn, including the vpn server itself.
when you added the new line, it adds a route to the client for just the vpn server to be reached over the inet gateway instead of the vpn.

That's sound logical.

What I still don't understand is why Windows clients worked perfectly even without this line. Any idea?
