Model: ER7412-M2  
Hardware Version: V1
Firmware Version:

My setup is I have fortigate firewall interconnected to ER7412-M2 (LAN of fortiate to WAN of ER7412)

I configured routing on both sides and firewall policy on fortigate to have communication to local subnets of ER7412-m2 and fortigate firewall.

Now i can communicate from local subnets of ER7412-M2 to local subnets of Fortigate but vice versa I can't communicate local subnets of ER7412-M2 from fortigate local subnets, I can only ping the  LAN gateway in ER7412-M2 but the local device is not.

I think it has somethin to do in NAT of ER7412 but there is no option to disable it.

 

How can I possibly fix this issue. Thank you!

Hi @Ataris, it might be easier just to connect the Fortigate firewall to a LAN port on the ER7412-M2 instead of it's WAN port.

  @D-C  Oh yes. I never thought of that. This will make things easier since the firewall will do everything. I will try that. Thanks

The latest firmware V1.1.0 for ER7412-M2 V1 adds a “Disable NAT” option—you can use this feature to meet your requirement.

  @Ethan-TP Actually this is my setup current setup after update same problem. still i cant ping host at er7412-m2. or maybe acl config? previously i cant ping er7412-m2 Lan gateway when i configured ACL rule on er7412-m2

Policy = Allow

Service type = All

Direction = wan in

Source = IP Group Any/Fortigate LAN Subnets

Destination = ME 

 

This solved me to ping LAN Subnet of ER7412-M2

 

Then i Tried to Add additional rule

 

Policy = Allow

Service type = All

Direction = wan in

Source = IP Group Any/Fortigate LAN Subnets

Destination = IP Group Any/ER7412-M2 LAN Subnets

 

Policy = Allow

Service type = All

Direction = wan in

Source = IP Group Any/ER7412-M2 LAN Subnets

Destination =  IP Group Any/Fortigate LAN Subnets

Perhaps you should configure it exactly as described in the setup guide I provided.

  @Ethan-TP  This  is from fortigate LAN subnet perspective.  LAN of ER412 no response but vice versa ping is ok.
