Dear All,

i'm checking the failover function of TL-MR6400.

i was able to apply the backup functions on router in order to reroute the outgoing traffic trow the 4G interface when the lan4 is down ---> OK

but now, i need to insert the NAT roules that working when the system is in backup 4G mode ....

my nat could be like this:

normal mode  --> interface Lan4 | external port 5051 to internal port 3389 | internal ip 192.168.1.10

backup mode  --> interface 4G| external port 5051 to internal port 3389 | internal ip 192.168.1.10    < --- this is the problem*

*when i try to save this roule, the system tell me that is it impossible becouse the port is already used...

I don't know if the firmware of my router is not able to manage this function, and i ask you if is it possible or not.

If is not possible whit this model, please tell me the right model ; )

best regards
