Does mitm6 work through tun0?

[RunRenegade]

Hi,

Tried looking around but can't get a concrete answer.

Relatively new to Linux and Networking, so trying to get to grasp with items.

I am trying to use the following command to connect to the homelab and run mitm6.

sudo mitm6 -d marvel.local -i tun0

I have ran the command also without -i tun0 but I assume it is needed or it will default to etho0 ?

I get the below output, but in all honesty, not sure what it means.

  cipher=algorithms.Blowfish,
/usr/local/lib/python3.11/dist-packages/scapy/layers/ipsec.py:485: CryptographyDeprecationWarning: CAST5 has been deprecated
  cipher=algorithms.CAST5,

  File "/usr/local/lib/python3.11/dist-packages/mitm6-0.3.0-py3.11.egg/mitm6/mitm6.py", line 57, in __init__
KeyError: 17

I have done and clean and recent install of mitm6. I am wondering if I am just trying to use a tool (mitm6) where it isn't built to work, such as through a VPN tunnel?

Thanks for any help or advice.
