Full Cone nat support?

[redpoisonv3]

i wanted to ask if this kernel adds support for full cone nat, since the stock firmware currently doesn't have it enabled.

Which functionality in the kernel are you referring to (that’s needed to enable full cone NAT)?

This page suggests it should be doable with iptables only: http://www.joewein.net/info/sw-iptables-full-cone-nat.htm

question how would i keep it persitant even if the udm is rebooted?

just a little stuck on how to adapt the rules to the udm

i wanted to be sure that the udm isnt missing something like this in the stock kernel

Sorry, I am unable to advice you on this since I don't have any experience with setting up a full cone NAT. I reckon you don't need a custom kernel module for this, but if you want, you can build that kernel module yourself with the kernel sources at https://github.com/fabianishere/udm-kernel.

You can create a custom boot script to create the IPTables rules on boot: https://github.com/boostchicken-dev/udm-utilities/tree/master/on-boot-script
