Wireguard - Some sites dont open

Networking & Firewalls
1

Hi all,

I used Toms video to set up Wireguard on pfsense and it works - partly.
I can connect the to the tunnel and can open some internal webpages.
I have two truenas systems running in the same subnet - one as main, one for backup.
I can only get to the web GUI of the backup one not the main one, Xen Orchestra web gui opens, jellyfin doesnt.
SMB share dont work at all.

Where did I go wrong?

Thanks for your help

You need to double check your rules and wireguard config to allow traffic to those subnets/IP addresses

Did you set your MTU?

Are you trying to connect by hostname or IP? Share your config?

@DroppedConnection Config for the split tunnel:

[Interface]
PrivateKey = hereIsThePrivateKey
Address = 172.16.16.2/24
DNS = 192.168.5.1, 8.8.8.8, 1.1.1.1

[Peer]
PublicKey = hereIsThePublicKey
AllowedIPs = 172.16.16.0/24, 192.168.5.0/24
Endpoint = dyndnsaddress:51420

I tried both, hostname & IP. For some IP it worked and for some hostname it worked. for me no pattern is visible

@David: No I did not set any MTU.

@xMAXIMUSx: The targets were all on the same subnet and some worked and some not, even the the Truenas GUI on two different machines behaved diffrently.

What about your firewall rules on the wireguard interface? Could we see what you have there?

Could try setting your MTU on the interface.

Havent had a interface assigned to Wireguard yet. Added the interface and added the MTU - no improvement
