    I've recently installed a new Edgerouter Lite at our office, and all port forwarding works fine except for 5060, where I receive an "unmatched mapping (1024)" error, while the rest of the ports pass. Does anyone have experience with the Edgerouter, and forwarding the ports for 3CX? I've disabled SIP ALG by using the CLI and that didn't help.

    Thanks!

    I'm using an EdgeRouter-X ver1.9.1.1
    forwarded both udp & tcp for 5060
    I get unmatched mapping errors for some of the media server ports
    System seems to function ok, but hasn't been up that long and no plans to put in production

    Did you manually forward the ports?

    I have the same issue on USG's (UniFi version of the ERL's). Doesn't seem to affect anything.

    Thanks.

    I'm sure I disabled ALG correctly, but I'd like confirmation... how did you disable SIP ALG?
