Might you help me?
There are some threads already about how do this.
You need to create firewall rules to allow:
- udp 32768:61000
- tcp 8008:8009
- udp 239.255.255.250:1900
And one rule to increase the ttl of the ssdp 239.255.255.250 broadcast
I found this info about chromecast ports online, i don't know how accurate this info is.
Maybe you have to enable the firewall log and watch for dropped packets and adjust the rules accordingly.
Then configure smcroute to enable routing of the mulicast traffic (239.255.255.250)
Something like:
mroute from br-lan group 239.255.255.250 to br-othernetwork
mroute from br-othetnetwork group 239.255.255.250 to br-lan
Change the network device names (br-lan br-othetnetwork) accordingly.
How do I put those ports in OpenWRT?
The firewall rules go into
/etc/config/firewall
by default the smcroute config is in
/etc/smcroute.conf
Over 2 years passed and I was never able to fix this.
