Do you use Win7? Your problem description sounds like mine in [url=https://forums.openvpn.net/topic11499.html]this Thread[/url].

Sudden loss of routing

Hi

I seem to have a strange problem.

My client can connect to my server and all works fine for about 5 minutes, then suddenly I just loose connectivity, can't browse or ping hosts anymore.

I really don't know where to start with looking at this, could someone please point me in the correct direction ? (I have checked and there are no errors on either server on client that are obvious) ?

Client config looks like this:

client
dev tun
proto udp
remote 1xx.xx.6x.2xx
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert user.crt
key user.key
ns-cert-type server
verb 3

Server config looks like this:

local 1xx.xx.6x.2xx
management localhost 7505
port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key  # This file should be kept secret
dh dh1024.pem
server 5.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "redirect-gateway def1"
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"
keepalive 10 120
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 9

I have just cranked up verb too 9 to see if that helps, but if anything jumps out as a problem i'd be grateful for feedback.

Looking in the client log I am seeing this:

Fix the to small issue by correcting:

comp-lzo

Still have the issue though 🙁
