How to enable bidirectional communication between wan side and lan side with TL-ER6120
Used to separate the internal domain network(fixed ip) by the second segment of the ip address.
Initially, communication between separate networks only needed to be done form the LAN side to the WAN side, so it was almost the default setting.
------setting-----------------------------------------------------
WAN1: Static IP
IP Address 140.aa.0.2
Subnet Mask 255.255.0.0
Default Gateway 140.aa.0.1
Primary DNS [DC IP Address]
Vlan 336(default)
LAN: IP Address 140.bb.0.1
Subnet Mask 255.255.0.0
Vlan 436(default)
Vlan: ID 1
Vlan ID 336
Name Vlan336
Ports 1(UNTAG)
ID 2
Vlan ID 436
Name Vlan436
Ports 5(UNTAG)
NAT: Default
Routing: Default
Firewall: attack defense
・Block Large Ping ×
・Block ping from WAN ×
VPN: Default
UPnP: Enable UPnP
Interface WAN1

However, it became necessary to temporarily enable operation from the WAN side to the LAN side.
I would like to use TL-ER6120 as it is, turn off the Vlan environment, and enable bidirectional communication, but I don't know how to s et it. Excuse me, but please give me a professor.
Here is what I want to do:
1) I want to treat the WAN as a LAN and use it like an L2 switch.
2) I want to ping from a WAN side to a computer without a LAN side network.
Please your cooperation.
