Hi, everyone.
I cannot access my server via External IP with flag Cd and SCFd in firewall connection.
Please see attachment.
Do you any advice?

Yes, config your device properly.
could you be more specific, please ?
Port forwarding??
Thanks for your responses,
I don’t have any port forwarding.
here is telnet’s capture from 36.88.xx.xx (from external)
and this case is only for single ISP (Internet Service Provider).
If I trace the route from another ISP, there is no problem.
