SOLVED I2P firewalled or symmetric NAT message?

Hello, everyone!

I am running I2P and would like to have it port-forwarded to help out the network. Even though I have port-forwarded both UDP and TCP, it always indicates "firewalled" or "symmetric NAT." As far as I am aware, I do not have a symmetric NAT. I run many other port-forwarded services without any issues, some publicly, so I am not sure what the specific issue with I2P is.

EDIT: After some more digging i managed to fix the issue while using docker. For some reason you need to add the environmental variable EXT_PORT to the compose file like so

    
services:
    i2p:
        image: geti2p/i2p:latest
        environment:
            - EXT_PORT=XXXX <Make this the same port as the public UDP/TCP port>
        volumes:
            - /XXX/I2P-data/i2pconfig:/i2p/.i2p
            - /XXX/I2P-data/i2ptorrents:/i2psnark
        ports:
            - 4444:4444
            - 6668:6668
            - 7657:7657
            - XXXX:XXXX
            - XXXX:XXXX/udp
