Solved How to access my Secondary WAN USB (eth8) during stand-by

[amplatfus]

Hi,

After implemented the solution posted on nearby thread (Solved How to access my ONT from router by @andresmorago), I was wondering is is possible to access the USB Huawei HiLink (used as Secondary WAN while is in standby.
I would like this in order to read SMS from that SIM while Secondary WAN is not active (USB HiLink have a build in web server).

Currently I can access it only when Secondary WAN is connected (I am using Dual WAN mode in fail-over).
When in stand by, I can PING it successfully,, but web page is not loading.

The Secondary WAN is mapped on eth8:

I think is would be possible. Now I am already happy while accessing my bridged ONT (eth0) like in mentioned thread (BIG thank you! #happy).
Please, could you help me?

Thank you in advance,

Hi all,

I have good news. I succeed by adding this to nat (/jffs/scripts/nat-startj:

iptables -t nat -I POSTROUTING -o eth8 -j MASQUERADE

Thank you all including @ColinTaylor and @andresmorago, @daviddrf for inspiring me here: ([Solved] How to access my ONT from router).
After posting this, I will mark this thread [Solved] too, like the inspiring one.

Much appreciated,
amplatfus
