OpenVPN client-server cannot access lan

[marvosa]

OP, this is what we need:

1.  Post the contents of your openvpn server config (server1.conf).  i.e.:

• Diagnostics -> Edit file

• Navigate to "/var/etc/openvpn"

• Post the contents of "server1.conf"

2.  Post screenshots of the firewall rules on your LAN and OpenVPN tab

@tsolrm:

What's your LAN?

I am not sure what you mean?

The backup file I posted should allow someone to completely recreate the pfsense box I am having trouble with, except the the WAN IP configuration, which I changed before posting.

What's your local network subnet? Go into Interfaces -> LAN -> Post your .../** number

[xerovis]

LAN subnet is 10.1.100.0/24

@xerovis:

LAN subnet is 10.1.100.0/24

That would be a problem. Put the VPN clients on an ENTIRELY different subnet, like 172.16.0.0 - 172.31.255.255

Yes and no.  Yes, in a routed tunnel your tunnel network needs to be on a different subnet than your LAN and everything else.  But no, he doesn't have to go to 172.16.0.0/12 because in fact his tunnel network is on an ENTIRELY different subnet:

Tunnel Network - 10.2.100.0/24
LAN - 10.1.100.0/24

So, he's ok there.

OP, as soon as you post your config and firewall rules we can tell you more.

Please find attached screenshots of my firewall rules.

These look like LAN and WAN rules, but there also needs to be similar allow rules on the openvpn tab

Crap - Sorry!


[kejianshi]

I see no problem with the rules…

Can you go to OpenVPN: Server, edit the server and post that page here.

I'm a simple minded guy.  Reading that is easier for me.

Your settings look good to me.
What is it that you cannot ping on LAN?
Various versions of Windows will respond to ping from devices on their local subnet, but not to ping from another subnet. Make sure to turn off any firewall on the LAN device. Make sure the LAN device has default gateway pfSense LAN IP, so it can answer.

[marvosa]

You have an any/any firewall rule on our openvpn tab and your config is nearly identical to my working config, so I suspect your tunnel is working as expected.

Most likely this is a software firewall issue.  If you're pinging a windows box, by default the windows firewall will deny ICMP echo requests from IP's sourced outside of it's local subnet.  Disable the windows firewall and test your ping.  If it works (which I suspect it will), and you want to keep the firewall enabled, you need to add a windows firewall exception that allows ICMP echo requests from all IP's.

Happy to help, but start a new thread, so we can keep everything straight.

I have the same issue here. It used to run flawlessly, but suddenly stoped. I already rebuilt the server, restored the configuration and got stucked on the server. Can ping, open the url in a browser but cannot reach any of the machines on the LAN side.
