kernel-qubes-vm 4.17 and 4.18 don't work for sys-whonix/whonix-gw based vms


#1

it appears the -j REDIRECT is blackholed somehow. on 4.16 and 4.14 I see the INPUT rules get hit but in 4.17 and 4.18 the INPUT rules are not hit.


#2

Could you report this to https://github.com/QubesOS/qubes-issues/issues please?

Can you provide more details? Cannot reproduce:

root@host:/home/user# { iptables -vnL -t nat; iptables -nvL; } |grep 9051

@marmarek what details do you require?

I am using both a whonix-ws-14 template as appvm and dispvms and neither work. templates do work but that’s probably because they use qrexec and the direct host network of sys-whonix which still works just fine.
