Connection to OpenVPN successful but unable to access local resources

[gg93]

Hi All,

Having a bit of an issue, had the OpenVPN service running smoothly for about 5 clients for 6 months.
Suddenly, I'm unable to access any local resources when connected on my laptop at home. I've also attempted to connect when tethered to my phone to ensure it wasn't just my home network.

I can connect to the VPN, and when i check on the firewall, there appears to be packets recieved, but when i try to remote onto a server, or open emails, no luck!

When connecting, i get the following messages:

On the OpenVPN client: I've masked the external IP as .*.*. for security

Does anyone have any ideas? I previously worked, stopped all of a sudden.
The VPN is running in bridge mode.

Let me know if you need any more information.

Thanks,

tun mode or tap mode?
What is your tunnel network? "remote networks"? Any client-specific overrides?

Hi Jimp,

Many thanks for the reply.

I'm running it in TAP mode and i have no Client Specific Overrides.
I'm running in bridge mode with Lan being the bridge interface and the local network being 172.18.200.0/24 which is our local network in the business.

Thanks,

FIXED

I went into the VPN interface, clicked 'Save' and all miraculously started working again.
got the idea from another Thread: https://forum.pfsense.org/index.php?topic=75142.0

Same problem too (vpn tap with certificate + bridge)

The vpn connects correctly (from logs either client and server side), but no traffic passes through it as interface is down.
Going to the interface properties hitting save makes it work

The problem doesn't happen with vpn tun with shared key to another location

Thanks for the help though!
