Cannot connect - from tutorial…
-
Hi,
I have followed the OpenVPN <-> windows client tutorial, but despite that I cannot get a successful connect. My ovpn client file looks like this:
float
port 1194
dev tun
dev-node ovpn
proto tcp-client
remote 100.110.120.130 1194
ping 10
persist-tun
persist-key
tls-client
ca ca.crt
cert tor.crt
key tor.key
ns-cert-type server
#comp-lzo ? to enable LZO remove the #
pull
verb 4… and here is an excerpt from the client's log for an attempted connect:

I have noticed that in this forum there are differences in the client's ovpn files in the different examples (some use UPD and the tutorial uses TCP) etc.
Thanks if someone would comment on my config and suggest amendments to try..?

Are you sure your firewall rule allows the right procoll?
Could you show a screenshot of the firewallrules allowing the traffic to the OpenVPN server?

Unfortunately I haven't the pfsense box in front of me, but I have enabled two rules on its WAN if:
One for ICMP which enables me to ping pfsense from the client (and when I disables this rule it does not respond to pings) hence I can be sure that I have contact with the proper external IP.
The WAN OVPN rule opens for port 1194 with protocol TCP/UDP all other columns are asterisks….
I tried another client ovpn file using UDP as protocol and changed pfsense's OVPN config to use UDP instead of TCP. Then I got lots of 'Connection reset by peer' messages at the client.

Screenshot of WAN rule and OpenVPN log (I think for the ovpn client config above). I hope this may give some more clues.
