The phone is connected to em1. Today, I do not have the phone to try. I suspect that something might be wrong with my iptable rules. Also, I do not know the uuid nor the MAC addy of the skype phone, so, I have no idea how to hardcode the LAN ip addy for the phone in /etc/dhcp/dhcpd.conf. If I knew the MAC of the skype phone, it would perhaps simplify the handshake between the skype phone and the computer (dhcpd). _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org If the client is plugged directly into the Ethernet port that dhcpd is listening on, why are you discussing packet forwarding and the wireless interface? I would tcpdump on em1 to verify traffic. 'journalctl -u dhcpd' should show requests and such. Also verify that the phone is set up for dynamic and not static address assignment, and perhaps test with a different client. --Pete
