TDA2SX: Port forwarding in arago linux

Eshwar J

Part Number: TDA2SX

Hello,

We desire to work with streaming application (using UART modem, "ping google.com" is successful). For this purpose we wish to forward port 80 and 554 for the connected ip camera.

Upon trying to run the following, option dport is not recognized

root@dra7xx-evm:~# iptables -t nat -A PREROUTING -p tcp -i ppp0 --dport 8001 -j DNAT --to-destination 192.168.1.200:8080

root@dra7xx-evm:~# iptables v1.8.2 (legacy): unknown option "--dport"
                   Try `iptables -h' or 'iptables --help' for more information.

Having tried to run the on same on ubuntu host, the command is successful even though the iptables version was 1.4.21

We made several attempts for port forwarding but unsuccessful

Please help on this. Any workaround or known methods to achieve port forwarding are welcome.

Thanks,

Eshwar J

Hi Eshwar,

I think this is a generic Linux networking or IP table issue, not related to TI software. Have you tried updating the IP table software using arago toolchain ?

Hi Vineet,

We have cross compiled the latest version of iptables-1.8.7 using arago toolchain. We are getting the same issue as below:

root@dra7xx-evm:~# iptables v1.8.7 (legacy): unknown option "--dport"
                   Try `iptables -h' or 'iptables --help' for more information.

Kindly help on this resolving this issue

Thanks,
Eshwar
