First of all, thanks for your fast answear
first for sure disabling firewall won’t help. as highlighted by Charlie in the same thread you point this is not a smart move. SME firewall is really user friendly in term of what it allows, and is just there to make thing secured if you are using server only, and to allow NAT to work on top of that if you are using server gateway mode.
I did it on purpose, just to check that firewalling wasn't the cause. Indeed, it wasn't
stating you use a server gateway this lead to the question please draw us your network because it sounds like a double NATing situation.
If you want to play with that you need to know what you are doing and able to configure every routing issues you are putting in place.
As a matter of fact, triple-NATing. From WAN to LANs : my ISP Box is set as router, subnet 192.168.0.x then a router/firewall shares connections to wifi and SME on 192.168.1.x subnet, the SME server is on the last subnet. Yes, I'm a bit paranoid, but I don't wanna mess Wifi and SME Lan-side.
I don't pretend I masterize that, but I've been working with that configuration for about 15 years, and never had to do anything more than managing redirections on the different routers.
I had forgotten to say that in my different tests I've tried a direct link between the SME server and the ISP box (with proper IP configuration) and the problems were the same.
also port 80 to administer a router seems pretty insecure in 2021.
Once again, I had opened it for this testing purpose
also not that random questions, what returns those 3 commands
I'll get back to you as soon as possible with these
I expect I'll have time to plug the newer disk in the next days.
Thanks again
