OpenVPN installed, iOS client connects, but no internet or local resources
-
Hi,
I'm not a firewall expert. Had another solution implemented, it worked well, but I upgraded internet speed and that last solution only recognized one of my intel pro1000 gigabit NICs.
Installed pfSense and was happy that it recognized both.
I went through the wizard, got OpenVPN configured, exported ovpn for client, imported ovpn in iOS, connected successfully.
But when connected from iOS to the OpenVPN:
I can't access internet.
I can't access local Plex server.However, I can actually see and login to pfSense at 192.168.1.1 when logged into VPN from cellular network on iOS.
What can I give you for you to be able to help me with this?
Thank you,
Dajo -
here's some things I found.
I connected again from iOS and got some logs:StatusSystem LogsOpenVPN:

When using an iPhone, using the OpenVPN app, I have the same logs.
You could also "find" the log on the client, although it would probably not show the issue.What do you have here : Firewall => Rules => OpenVPN ?
-
thank you!
-
Firewall rule looks fine.
Your OpenVPN setttings ?
Check also your settings with the official OpenVPN videos (Youtube => Netgate).
-
on your iphone you should see way more logs than that - like your routes being added, etc.. if no routes add then no your no going to go anywhere.
example just connected with my iphone XR running the same openvpn connect app

I have :
Which allows my clients to connect to "everything".
-
yeah you can do that if you want.. I don't - but he doesn't show that either in his log..
Also looks like he is using 192.168.2 as his tunnel - if that steps on his local network where he is connecting from - then also another bad day sort of thing.

ok, guys, besides screenshots above and iOS openvpn connect app logs, please let me know if there i anything else I need to provide.

I compared your settings with mine.
I have 192.168.2.1 as a DNS for VPN clients - not the LAN based DNS.
Your LAN rules : remove (temporality) the source "LAN Net" here.
You're not using IPv6 so "IPv4 only" seems more logic to me.
When you are connected, can you ping 192.168.1.1 ?
Can you ping a device on LAN, like your plesk server ?
Does DNS work ?
Test with Resolver in pure Resolver mode (1.1.1.1 and 1.0.0.1 aren't needed anyway). -
No internet - could just be that you can not resolve.. Did you set the resolver ACLs correctly? Out of the box it will auto allow your local networks, but not a tunnel network.
As to getting lan clients - do their firewalls allow access from your tunnel network?
No need to remove lan net as source - that has NOTHING to do with traffic from your vpn tunnel.. And is correct..
-
when connected to OpenVPN tunnel from a cellular network through iOS, yes I can actually use safari to log into pfSense firewall at 192.168.1.1.
as far as clients firewalls allowing access from tunnel network, I don't know. Using my previous firewall solution as soon as I connected to OpenVPN, I could access my plex server no problem. How can I allow access from "tunnel" network?
As far as setting resolver ACLs correctly, I have to learn how to do that.
Also, the routes that I see in johnpoz OpenVPN client logs: I don't see routing on mine...
-
I assume this is the setting you're talking about, johnpoz... nothing there... -
So your using the automatic ALCs, which I do not believe adds your tunnel network.. So no you wouldn't be able to resolve anything. if your asking unbound on pfsense.
As to routing, if your using the default all through vpn your fine. But if you can not resolve this would explain no internet, and might also explain no plex access if your trying to resolve it vs access it by IP.
-
i understand now. Undernetworks in the above screenshot, should I add 192.168.2.0? -
Yes you should add your tunnel network and the correct mask for your tunnel network ie using /24 I do believe.
I disable the auto acls - so I manually add them
But default is enabled, so as you see only internal networks are allowed - not tunnel networks.
Should prob check any docs about setting up openvpn and make sure this mentioned, or make sure the tunnel networks are auto added, which I do not believe they are - but would have to double check that... The quick way to test is just do a simple query to your unbound running on pfsense from your vpn client. To validate if you can resolve or not.
-
thank you! adding the resolver settings for tunnel network fixed it.
I appreciate all of your help very much! -
I have this
Isn't that default : non-checked ?
My Resolver ACL list is totally empty.
I can reach all my LAN's just fine from using the OpenVPN.A not working DNS should not impact a ping to a LAN IP, the Plesk device.
-
Non working dns doesn't stop a ping via IP, but stuff doesn't work if your trying to use fqdn to ping ;)
