MX64 convert LAN port to WAN

[Mostafahasanin]

I have an MX64 firewall with two WAN ports but i have three internet lines so i need a LAN port to work as a WAN

is it possible ? if yes, how ?

Unfortunately, no. The MX64 supports only two WAN interfaces.

thanks rbnielsen

I need to know that, are ALL MX don't support or there are some models can support converting LAN to WAN?

[rbnielsen]

The MX67C/MX68CW contains a 3G/4G modem which can be used for cellular failover (3rd WAN interface-ish).
Otherwise, no. All MX'es support only 2 WAN interfaces.
MX250 and up, have two dedicated ports. MX100 and below, has one dedicated port, and one shared, which can be converted.

[Mostafahasanin]

that's mean in MX64 I have one dedicated WAN port and one shared port.
does the shared port is a specific port or any one of the 4 ports can be converted ?
and is there any unexpected issue can happen when converting the port from LAN to WAN?

[rbnielsen]

On the MX64, only LAN4 can be converted to WAN, and requires access to the Local Status Page, inorder to conver the port.

There is definitely no method of using more than two wired WAN's on nay of the MX line

We did a rollout earlier this month on 5 remote sites which have three WAN's (2 x Data and 1 x VOIP) we had to use a Z3 for the VOIP lines

Great

but, after converting the port, can I load balance traffic that is going to the internet between the dedicated WAN port and the converted port.

[Nick]

You can indeed - it becomes a normal WAN port so the device has dual WAN

[Mostafahasanin]

that's good
thanks for all of you @Nick & @rbnielsen

In case anyone comes across this thread - it has been possible, for some time, to convert the nominated LAN port for a small MX to WAN (and back again, if desired) through Dashboard itself:   Security & SD-WAN > Monitor > Appliance status, in the Uplink menu.   Note some models use a different port as the hybrid, e.g. MX64 = LAN4, MX67 = LAN2.   References are in the respective Installation Guide (search 'toggle')
