TAP Interface Ubuntu 20.04

Post by BarbaxX » Wed Apr 28, 2021 11:04 am

Hello,

I want to be able to access my server that has a local bridge to en0 set up.
I followed various tutorials for setting up a bridge and connecting en0 with tap0 (created by Softether) but when created I cannot reach the server anymore. The tutorials don't seem to be up-to-date as they sometimes reference network manager, sometimes another linux network service.

Has anyone got experience setting up this linux bridge in 20.04?

Also I cannot access my main routers web interface. I can ping it though.

My network is 192.168.100.0/24.
Connection is L2TP/IPSec.

Any help would be appreciated.

In that guide a DHCP server and routing tables are being defined. I don't need that, since the bridge interface should still be passing the DHCP requests to my router. I'm not sure why dnsmasq is being used in the example...

Have you tried "dhclient br0" once the bridge is up?
