Some Host not accessible via VPN
I got another issue with my pfsense:
I am able to connect from outside to our openvpn, I can access the interne via our pfsense gateway without any problems.
On the internal side there are some strange things happening, Some hosts are accessible, some not.
xxx.xxx.xxx.1 pfsense istself, working
xxx.xxx.xxx.2 windows server with company server software, working
xxx.xxx.xxx.3 raspberry with baikal, working
xxx.xxx.xxx.11 to xxx.xxx.xxx.22 ddwrt Wlan APs around the house, not Working
xxx.xxx.xxx.81 NAS working
xxx.xxx.xxx.250 switch working
xxx.xxx.xxx.251 switch working
xxx.xxx.xxx.252 switch not working
and so on
I don't see any pattern in it, form within the network, alls hosts are respoding fine.
Without seeing a diagram of how this is all wired together, my first guess would be that there's an improper setup of an internal firewall or configuration setting in the devices that don't work.
When an external client connects via OpenVPN, it will appear to an internal device that it has an IP address outside the internal LAN.
Some devices either fail to recognize or actively block those types of addresses.
The other possibility is you've got something(s) wired wrong.
Without a diagram, it's pretty hard to say.
