3.18.2 breaks forwarding #472

Open nW70M1 opened 1 week ago

3.18.2 breaks forwarding through a VPN gateway the same as 3.18.1 does. Rolling back to 3.18.0 as the last working version resolves this issue.

hi, thanks for reporting this. We'll try to reproduce this and let you know in case we need any information.

@nW70M1 could you please provide details about your setup? And how are the external devices connecting to it? Thanks

Devices are directed to the VPN gateway via PBR on a router. The VPN gateway is Debian with forwarding enabled and iptables rules for masquerade and forwarding between the machine's NIC and the nordlynx adaptor. This has always worked well up to versions 3.18.1 or 3.18.2.

I'm also experiencing this. I'm running nordvpn on my Raspberry Pi (rpi5 8GB). It's connected to my router (and thus the internet) using a lan cable, and its wifi chip is used to set up a wifi network (clients of which I intend to be routed through nordvpn). I'm running nordvpn and both the subnet of the wifi and that of my router:a DHCP are in the allowlist. Port 67 is also in the whitelist to allow DHCP requests.

I was running nordvpn 3.18.2. My wifi was working, and when nordvpn was connected, wifi clients were able to access the internet. However, when nordvpn was connected, they weren't. I tried a lot of different settings, but couldn't get it to work.

Then I found this issue and downgraded to get 18.3.0 and suddenly everything worked as intended.
