This says that anything with a source address 10.239.239.0/24 (ie virtual machine) will have the source address changed to 192.168.108.2; this is so that the BB modem does another NAT setting the source address to my external IP address. While I am debugging this, to avoid complication, I have set: iptables -A FORWARD -j ACCEPT and this is not a problem ... evidence is outgoing packets with source address 10.239.239.23 -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers Ltd.
