Windows 7 OpenVPN client can't reach the LAN

georgeman

Did you run the OpenVPN client as administrator on Windows 7? (right-click, run as administrator). Otherwise the route won't get added properly (although on the screenshot it looks fine)

I sure did.

All you posted looks fine for me.

Check also your Outbound NAT settings (I have just read a topic where that was the problem). There shouldn't be any rules for the OpenVPN interface

Automatic outbound NAT is switched on. No other mappings.

Is it possibly an issue that my VPN tunnel network (10.12.43.0/24) is within my LAN (10.12.0.0/16)?

And is this firewall rule on the OpenVPN interface sufficient?

Switched the VPN tunnel net to 192.168.20.0/24. Still nothing travels into the LAN. :-\ I've temporarily disabled the firewall on the client. Doesn't help though.

Does this entry in the log shed any light on the problem?

Do the clients on the LAN allow pings from the OpenVPN network? Try to turn off firewall on the clients temporarily.

marvosa

Export a new config and install it on the client-side.

Post new exported client config.

Post Pfsense routing table.

Post client routing table once connected with new config.

Thanks for your input.

The quantity of issues I'm having with pfSense is rising, Now I'm getting failures on attempting to log in:

Warning: session_start(): open(/var/tmp//sess_1e36ef0d17d9b13cdeb3d59c25e8e0ab, O_RDWR) failed: No space left on device (28) in /etc/inc/auth.inc on line 1357

There's plenty of space, so I'm going to guess there's some filesystem-level corruption of some kind, in which case all bets are off. sigh Time to reinstall.

Rob Pomeroy

Completely reinstalled pfSense and what do you know? It's working.

Hypotheses:

Corruption of original installation and/or
Using older version of OpenVPN Client Export pacakge and/or
Some other installed package caused a problem (have installed this fairly lean on this occasion).

Thanks to all for your help. I'm going to snapshot this virtual machine while it's working!!!
