Fortigate 60E - Interface WAN Giga working only Fast

[Romulo]

Hi community,

I have bought a used Fortigate 60E to work with SD-WAN. The port WAN2 not working (no sign of life) but my problem is the port WAN1 because it's working only Fast. My service provider router is Giga and my link is 500Mb. What is the problem?

I count with your support

Addtionals Informations:

- The two WAN ports are 10/100/1000;

- My firewall is up to date - version 7.0.12;

- Memory and CPU used is OK;

- When i tested the same cable on another port, it's works Giga (Today, it's my workaround);

- When i forced the speed port to 1000, it's stop work;

1, Make sure the interface is set to auto or 1000full in the CLI
2, Test with a known-good(!) cable and a known-good (!) device on the other end of that cable.

3, If the FortiGate still can't negotiate/function on 1000full, then the WAN1 port is most likely also (half-)broken. Proceed with RMA if the unit has support coverage, or being sad if not.

It's worth noting that there's nothing stopping you from re-purposing one of the (hopefully still functioning!) internal1~7 interfaces, or the DMZ, as your new "WAN" link. You won't lose any functionality nor suffer any performance degradation by doing this (apart from the visual simplicity of a WAN interface being named WAN1/2).

Hi,

1 - The interface is et to auto;

2 - Like i have mentioned on my topic, i tested the same cable on other port (internal7) and works;

3 - So i will be sad! haha

My workround was used the ports internal7 and internal6 like WAN ports. It's works without problems and on giga!

I had a similar issue when I just now replaced a FortiWIFI 30E with a FortiGate 60E.   My signal to the ISP router goes through bad CAT5 cabling over about 50m, and the 60E WAN interfaces would go to 100tx, or just disconnect, whilst the internal ones would stay at 1000tx if I tried connecting them to the RJ-45 from the ISP router.  My solution was just to put a crappy TP link 1000tx desktop switch between the Fortigate 60E WAN port and the cable from the ISP router to boost the signal.  Go figure.  Makes no sense why the WAN interfaces would be more sensitive than the LAN ones.  The 30E negotiated 1000tx no problem, same cabling.
