Hi All,

 

I have been trying to find an answer as to why I cannot access a specific Docker from different vlans/subnets. I have multiple vlans and subnets that are working perfectly, but I cannot get any of them past Letsencrypt to the Docker it is protecting.

 

Basically, any vlan/subnet that is not on the Letsencrypt/Nextcloud subnet cannot connect to Nextcloud; anything on the NC subnet connects as expected, including externally. I really have researched this and cannot find a solution. Obviously I am still new to complex networking, but I do have a decent foundational understanding.

 

Does anyone have any thought as where I can research the solution to understand this dilemma? Thanks!!!

I think this is macvlans doing.

Gotcha. So because Letsencrypt is probably creating a private macvlan, it is dropping/refusing anything outside of the vlan/subnet it is on.

I am going to try the folks over on the LE thread and see if they can verify.

Thanks for the pointer!
