Invalidate PPPoE interface on WAN2.7

Hi All,

 

PpoE works fine on Cisco router but doesn't work on Fortigate 60 F, getting below error.

Two suggestions:

1- make absolutely sure you have the password correct (i.e., paste it)

2- some ISPs deliver on a VLAN, that is, tagged. If your modem doesn't remove tags this might be the issue.

Aslo check for other ports and try wan connection.

Hello Siddhanth, 

Thank you for your reply 

1- Yes, password is correct

2- ISP is tagging on VLAN7 , same VLAN tagging works on Cisco. 

 

Do you see anymore issue? or the only option is to check by changing port ?

Can you share "show sys int wan2" and "show sys int wan2.7", after masking username/ENC password of course.

Hello Toshi, I dont have device access as of now, but below is what I have configured

 

config system interface
edit "wan2"
set vdom "root"
set mode ppoe
set allowaccess ping https fgfm
set type physical
set role wan
next

edit "wan2.7"
set vdom "root"
set mode pppoe
set allowaccess ping https fgfm
set device-identification enable
set monitor-bandwidth enable
set role wan
set username xxxxxxxxx
set password xxxxxxxx
set interface "wan2"
set vlanid 7
next

end


config router static
edit 11
set dst 0.0.0.0 0.0.0.0
set gateway x.x.x.x
set device wan2.7

next

end

First, remove pppoe from wan2. Only thing you want to configure is changing the default dhcp to static so that it won't pull any IP on the non-tagged interface. Leave the rest unchanged.

VLAN 7 interface seems to be ok.

If it still doesn't work, sniff packets at "wan2.7" if you can see any meaningful traffic. If not, sniff it at "wan2" interface to see if it's actually tagged with VLAN 7. Below is the output on my 40F. All traffic is tagged with VLAN 201 (Lumen).

fg40f-utm (root) # diag sniffer packet wan
interfaces=[wan]
filters=[none]

Thanks Toshi, will check this on Monday and let you know

Toshi_Esumi

One more thing. PPPoE generally pulls the default route into routing-table. If you DON'T want it but want to use a static route, you need to set "set defaultgw disable" on "wan2.7" interface. But I would suggest removing the static default route first and let PPPoE pull the default GW.

Once you confirmed it's working, you can change it to manipulate the default route(s) with static ones.

By the way, the current static route is technically illegal or conflicting with your interface config. If PPPoE, there shouldn't be a static gateway because PPPoE pulls it. Instead it needs to have "set dynamic-gateway enable". That's why I'm suggesting removing it.
