@teha 

 

Enabling SPI will block the access from outside to the local network, while it won't affect the local devices, they still can access internet.

 

Therefore, theoretically, it won't affect the network connection of the clients. 

 

When the 403 forbidden error pops up, please click here to verify whether your client has obtained valid IP address. 

 

Then try to login to the web UI and show us a screenshot of the status page. 

 

And try to ping the gateway of TD-W8951ND and google.com. 

 

Good day

@Kevin_Z 

 

thanks for reply

ok. when we enable SPI access from outside to the local network get block and every thing work ok

but 

me say: my client is a web server. my site is on this client. http://thaco.ir/

my client is a vmWare machin taht install direct admin on it

with this senario: when me enable SPI, this means my NAT dont work and this means my server down

is correct when me enable SPI, my client still have internet, but important is server work, so me have to off SPI & when off SPI, me take error 403
me think error is from framework

when me take error 403, The modem internet light is on, and me think modem block my access, because me have ping in that time

me attach picture
