Hi, 

I know that tp-link will no correct this issue. And tp-link will say vpn connection is remote connection. But this is very stupid issue. i cannot ping other VR600 from other office. when My 2 diffirent offices connected over IPSec VPN with VR600 I have to enable remote ICMP Ping for remote. It is very stupid idea. VPN is secure connection. And each VPN connections have local IP. Why i have to enable Remote ICMP Ping? Everyone can ping my device over internet when i enabled the romete icmp ping :) 

And i controlled all model of tp-link. They have maximum 2 firmware upgrade files. I understood that tp-link does not want to develop their devices.  

Also I have TL-ER604W I cant see VPN connection like interface when i wanted to add static routing. there is no option for VPN interface. All this type VPN Routers of other brands have a option for that. But TP-LINK products do not have. 

Also TL-ER604W does not communicate with SNMP Monitoring device which is runnign other local network over VPN. I have to install SNMP Monitoring device for each local network. 

I dont know. But i dont think buy tp-link device again. Those are last devices for me. Everything is impossible.
