Firewall disabled blocks my Pi

Hi, i have a RaspberryPi connected via ethernet to the Hub3 which i use to access my network remotely. I have forward all necessary ports, 22, 80, etc and it has always worked perfectly.

Now my gf needs to use a VPN for work, and i see there are issues with virgin hub 3 not being able to select IPSec pass-through (videos online show this being done on hub2). So, her vpn to work only works if we disable the Firewall in the hub.

Burt now if i try to connect to the Pi, ssh for example, i always get "connection refused". Why is Pi being blocked when Firewall is off? Are port forward rules not enforced if Firewall is off? Anything i can do to access the Pi while keeping Firewall disabled?

Thanks

Hello

If the firewall is turned off then no port forwarding will work, I am afraid to have port forward working you have to have the firewall enabled as that is what does the forwarding.

I see. Understood.

Solution is have Firewall back on and try to figure a way for the vpn to work as well.

Thanks for the reply Mike.

Re: Firewall disabled blocks my Pi

The only configurations are

Hub 3 firewall.

On for port forwarding to work.

Off for VPN to work.

You could use modem mode and get your own router with 1Gb ports to have both VPN and port forwarding.

Re: Firewall disabled blocks my Pi

Port forwarding is essentially a firewall rule, that is why it has to be turned on. With a good quality router you can see all the firewall rules and adjust them to whatever you want. The VM hubs being a cheap modem and router lacks many facilities that are needed by a large number of people.
