Just set the gateway on your windows VM to 10.1.1.1 and that should give your windows VM internet access

So have you amended all your network settings ?

is vmbr0 now on 10.20.30.1?

did you update the itables rules from 10.1.1.0 to 10.20.30.0?

if you do a traceroute from VM to 1.1.1.1 does it follow the expected path?

Sorry meant iptables rules

You will have to edit the /etc/network/interfaces file

Then restart networking
