VPN server and openswan: ipcomp module missing

Hello everyone, i already posted something here recently, but i stumbled over another problem that i just can’t solve. I followed several tutorials on how to set up an setting L2TP VPN server and always at the end, when i had to restart the openswan service, i get the error “module ipcomp currently not loaded” and according to nmap (i scanned from another computer) there are no ports opened apart from the ssh port.

so, is the missing ipcomp module the problem, why the VPN server isnt working, if yes how do i “load”/activate/install it? if not, what else could be wrong?

i appreciaty any help because i have literally no idea what could fix the issue… Also, i’m running raspbian for bananapi

have a nice day,
