Open
opened 3 months ago by EmanuelLoos · 0 comments

When forwarding a port in libreCMC all incoming packets are modified as if the origin was the libreCMC router. This can impair online services listening behind the router:

  • email server's SPF checks fail
  • ...

I also found an archived OpenWRT TracTicket regarding this issue.


I am experiencing this issue on my Netgear WNDR3800 with libreCMC v1.5.9.


Does anyone know of any way to change this behaviour?
