Bitdefender Firewall not working with expressvpn after update to 27.0.18.96
After bitdefender updated to version 27.0.18.96 today the firewall is no longer working when connected with the expressvpn app, it's no longer making rules when using the expressvpn app on windows, even when I manually add firewall rules for example firefox it does not block connections to websites when I disable the firefox rule when connected with expressvpn, the firewall does work normally when not connected with the expressvpn or when connected with the bitdefender vpn (I only have the free one so can't really use it anyway). I have this issue on 2 windows 10 computers since just today.
The previous version 27.0.16.87 also had the firewall not working, you guys from BD then fixed it to your credit within a few hour and it worked normally after the fix also with expressvpn but now again after the update to 27.0.18.96 it doesn't work properly again! What's going on? Is this going to become the norm now?

Hello @Petersl,
Check the default application behavior firewall settings and see if it's set to allow for the express vpn adapter.

It was set on automatic, when I set it to allow it still doesn't make any rules and when I set it to block it doesn't even block anything when I'm connected to the expressvpn. I have reset the rules and the only rule that's being made by the firewall is for the lightway.exe (this is a component of expressvpn) when I connected to the expressvpn, if I however disable the lightway.exe rule it does block traffic. Does this mean that all the rules are routed through the lightway.exe firewall rule when I'm connected to the expressvpn or does it mean when I'm connected to the expressvpn I basically have no firewall? It works normal when not connected to the expressvpn app.

In the Firewall settings, have you enabled Alert mode, restarted your PC, then ExpressVPN, and see if you get any connection notification(s) to allow it?
Otherwise, you should contact Support from the link below. Go through the How To's and Troubleshooting prompts until reach the black Contact Support box. You will have three options, Chat, email and phone support, which is not toll-free. Chat can be the quickest way to get things started. They will probably want you to send a log file or two, but they will let you know what and when they need those.
Kind regards,
Scott

I contacted support and they advised me to reinstall bitdefender which I did and I also reinstalled the expressvpn app, however the problem persists with the expressvpn app. I have now installed nordvpn as an alternative and that one works with the bitdefender firewall without issues (so far).
I will submit a ticked to expressvpn to make them aware of this issue.

Thanks for letting us know where you were at with this issue, for keeping us up to date, we appreciate it.
Don't let @Alexandru_BD know :) but I also have NordVPN on this notebook and have had very good results with it, no issues on my end.

There seems to be a serious bug with the latest update. Somehow it mangles the drive letter name on applications trying to send packets, making existing rules not working. It tells me some application on "F:\\" is asking to send a TCP packet, whereas the exe is actually on "C:\" drive. Note the double backslash too, not sure what is up with that. I should note the F drive is the last drive (alphabetically) I have an assigned letter for, this might be relevant in tracking down the bug, might be an off-by-one bug, or something like that.

Bitdefender firewall works with northvpn but it have noticed that when I'm connected with northvpn when I launch an application for example firefox it does not give a notification in the tab "notifications" when I launch a new program the firewall has not yet set a rule for, it works normal without the northvpn.
It's not a big deal cause the firewall does seem to work with northvpn, I tested it by disabling the firefox rule and when I do that firefox can't connect to sites, when reenabled the rule it can so it works. Just want to let you guys know cause I'm sure that's not intended.

A friend who has bitdefender and also runs the expressvpn app has the same issue with it, when connected to expressvpn his firewall makes no rules and existing rules don't work and the "access application" tab in the firewall settings is blank when connected to expressvpn on my friend and my bitdefender, it works normal showing apps allowed by the firewall and the firewall rules work normal when not running expressvpn or when running norhtvpn.

Bitdefender support has let me known that the developers are aware and are currently investigation an issue that causes this issue with expressvpn and the bitdefender firewall, they told me they will automatically update bitdefender when they have a fix.
