Manual port mapping for SIM-enabled router
Am a very excited new owner of a Flex 6400. My first experience with SDR was with the Icom 7300; it was my first radio purchase (am in the hobby just about 3 years). My current experience with the Flex is always compared with the 7300. The possibilities are incomparable. I felt greater growth possibilities with the Flex…
I have installed Smart SDR 3.1.8 with the accompanying CAT and DAX programs. I have installed SliceMaster and FRStack without problems. I have been using JTDX since I got it installed. In the 24 hours since I got hold of the Flex 6400, I have logged about 60 QSOs in the 15, 17, 20 and 40m bands. Am using a hand-me-down Cushcraft R7 vertical (the internal ATU of the Flex 6400 can tune every single band of the R7, while the internal ATU of the Icom 7300 can tune only the 10, 12 and 15m bands). But this is another story. I know I have to use a better antenna to do justice to the Flex…
My problem is with port mapping the router - I have a SIM-enabled router (IMEI 868842031305341). I can put the Flex (and its antennas) anywhere with wireless internet connectivity and logging-in remotely to the Flex has even (literally) wider possibilities!
Googling the IMEI of the wireless router does not give much information. The device does not seem to have UPnP. I have read the pertinent instructions in the Flex community –

But still I get a RED BUTTON on testing Smartlink.
My problem basically is, how do I tell the SIM-enabled router that Forward TCP Port 21000 (external) maps to 4994 (internal) and Forward UDP Port 22000 (external) maps to 4993 (internal)?Below is a screenshot of the port mapping page of the router… Any help would be appreciated!
Destination IP is the LAN address of the Flex. I have made this IP address static.
Destination ports are (internal) 4994 and 4993.
Again, how does this router know that these ports map to (external) 21000 and 22000?
