Then I have to connect to the guest wlan as well. It's no a good solution.
HI, have you found a solution?
I was thinking of nating chromecast to an IP on the guest network from your main one.
ex. you assign a static lease to your chromecast on your main network, say 192.168.0.100, and then nat it to, say 192.168.100.100 (must be out of the dhcp range but in the same subnet), on your guest network. This way it is reachable from both the networks.
I have the same problem and I'm struggling to find a working solution.
@artioni81 did you succeed with your proposed solution?
If so could' you share it?
If this is the case, it's only a limitation of the device's software.
I googled a bit :>
chromecast uses the following ports
udp 32768:61000
tcp 8008:8009
dlna broadcast
udp 1900 239.255.255.250
the dlna broadcasts needs to be routed between the networks,
i use smcroute for this.
The ttl of the broadcasts also must be increased by +1.
How do I put this data in OpenWRT?
I have two subnets ("lan" and "guest") and I want the guests to be able to send content to the Chromecast that is connected to the "lan" network.
A user directed me to this topic.
I know I did, for one. And I also:
I did not realize it was you. I already installed the package. Now what do I do?
Could you give me some example command to be able to adapt to my network?
Honestly, I cannot. This is why I linked you this thread and provided the instructions. Perhaps @shm0 can elaborate, as he is the one who suggested this software:
Then I see how I configure it, without first having read the website.
Might you help me?
There are some threads already about how do this.
You need to create firewall rules to allow:
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?
