- Once device is booted make below changes and reboot the gateway,These changes will be upstreamed soon ..
- Allow erouter0 in /etc/avahi/avahi-daemon.conf
allow-interfaces=erouter0
- Make publish workstation yes
publish-workstation=yes
- Iptable rule to enable mDNS traffic,These changes will be upstreamed soon ..
iptables -A INPUT -p udp -m udp --sport 5353 --dport 5353 -j ACCEPT
- Inorder to ssh to the device using hostname from a Mac book "ssh root@RaspberryPi-Gateway.local please stop the firewall for timebeing as a workaround for testing.will be sharing a fix for this in a while
