hello,

i bought a new device and i have setup ppoe client, dhcp and ddns have problem... i get"DDNS server received request from IP 94.66.59.xx but your local IP was 100.72.96.xx; DDNS service might not work"
the isp router is on bridge mode
when i chek my ip on www.myip.is i get 87.203.100.xx

for me it usually generates timeout, it gets more time out than active.
so I gave up.

mcnick50 - Please send supout file from your router to support@mikrotik.com. We will find out why did you experience such situation;
juliokato - Upgrade to 6.43rc (disable DDNS service before an upgrade), if you can use rc version on your router. Cloud service is completely re-worked and works much better now.

the problem was from my isp that was giving me ip starting from 100.xxx.xxx.xxx i called them and they fixed it. and everything worked after that

be only for testing until I can do it.
But I can not put the RC in production.
I prefer to disable the cloud of MK and use a DDNS own that I have configurate.

Now I realized.
how does MK release a new Cloud that works better only with RC firmware?

Here it's only connecting... with cloud enabled or not. No error message... (6.43rc)

The 100.64.0.0/10 address block is reserved for Carrier Grade NAT applications (RFC 6598). Now that the IPv4 address space is more or less depleted, ISP's revert to CG-NAT when they need to connect new customers. Hopefully they give them IPv6 addresses as well.
Only when a customer starts complaining they will get a public IPv4 address (if they ISP still has some left), but many consumers won't notice and won't complain.
