Touchstone CM8200A with EERO

John Blackburn

I have deleted and reset port forwarding half dozen times and still it doesn't work! Any idea's appreciated! 73, John WR8D

I have a CM8100 with Eero Pro 2 mesh.

Here’s the guide from Flex

https://edge.flexradio.com/www/uploads/20200818184955/SmartLink-Quick-Start-Guide-for-SmartSDR.pdf

i needed to do a DHCP reservation for the radio first, then do port forwarding for that reservation. In the zero I set port 22000 internal TCP to 4994 external TCP. I then in the EEro under same reservation do internal UDP port 21000 to external UDP 4993.

In SmartLink setup I set manual port forwarding. TCP to 22000 and UDP to 21000.

Now big thing is check your WAN IP in the router. If it starts with 10. , 192.168., or 172.16 then your ISP is doing carrier grade NAT meaning they are using one IP for many customers. They would have to do port forwarding on their end to your WAN IP.

Appreciate your reply Dave. I'll give my isp a call! Thanks

John Blackburn

I've not called the isp yet Dave but just checked the wan ip and it does start with 10! Thanks again! 73

Dave,

I appreciate all the info you've forwarded to me but my problem was with the EERO. I had my ISP enter the ports from their end as you suggested! Both ports showed active and green lights... then they discovered the device was blocking all commands from their end. They could not change the IP for me or anything else. This has been long journey for me over something that usually is simple to setup. The EERO even started forwarding both ports for a day or so then stopped. This morning a tech showed up with new gear and removed the EERO... within ten minutes both ports were up and running perfectly with a different design device. This ordeal started 12/17 and ended today 12/27. I hope others don't have the same problem with this EERO device that I have... but all I can say is I am glad it's gone! Thanks for all your help!

Happy New Year, 73 John WR8D "EERO FREE" "lol"

Dave, I'm not an IT guy and I continue to struggle trying to get this working...can you tell me what you mean by "DHCP reservation for the radio first"...thanks in advance... The isp assured me that my wan IP isn't used by other customers!

What are the first three octet of your WAN IP as shown in the Eero router? (IP is something like 129.45.67.118) notice it is broken into four groups of numbers. Each group is an octet. If your WAN IP starts with

10.

172.16

192.168

then those are non-routable IPs meaning your ISP is doing double NATting and would need to do port forwarding on their end.

As far as Eero DHCP reservation and port forwarding, I would suggest you contact Eero support. Then can guide you to setting a DHCP reservation for your radio, then set up port forwarding to the radio.

That is the best answer since you are not familiar with networking.

Dave, I'm sorry I have no experience in networking. But I do already have the DHCP reservations for the port forwarding on my Fex 6400 already set up! port 21000 4994 TCP and the other one is 22000 4993 UDP... I wasn't schooled on the Eero terminology "sorry". I had my ISP set both those ports up for me and they show working... The user interface of the Eero shows both ports with green lights...The home wifi port is 4993 and is working perfectly... the Smartlink port of 4994 keeps coming up with a -1 every time I run a test! It refuses to connect and everything is verified and paid for!
