System Tools -> Diagnostics -> Ping do not work on VPN
System Tools -> Diagnostics -> Ping do not work on VPN
2023-10-03 21:02:02
Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.1.2 Build 20230210 Rel.62992

The VPN tunnel is working properly but

 

pings (from System Tools -> Diagnostics -> Ping) do not reach devices on the other side of the VPN tunnel.

 

"Block Ping from WAN" is unchecked in firewall.

Hi, I wonder what kind of VPN did you use? And what's the destination IP to your ping? The assigned IP or the true IP?

VPN: IPsec

 

Fist router is: 192.168.1.1

Second router is: 192.168.2.1

 

I can ping from (diagnostic tools) 192.168.1.1 to 192.168.1.20,

but I can not from (diagnostic tools) 192.168.2.1 to 192.168.1.20.

I didn't have this type of problems when I used the same type of vpn on cisco routers (RV042G).

I got a question. What if you try the router's default GW IP?

So, you said the tunnel is up, at least you should be able to ping the default GW IP.

 

Need more details about your config if you can share it. The IP area is important to learn and diagnose.

Do you have ACL for this? I am pretty certain that IPsec, site-to-site VPN, should be accessible to each end. But in your case, it is not. Something else must interfere with this.

 

What other settings do you have except for the default and VPN settings?

When I ping from 192.168.1.100 (desktop, Windows 10) to router 192.168.2.1 everything is OK.

Only diagnostic tool (router, 192.168.1.1) can not send ping to router 192.168.2.1.

Hi @sdgf 

Thanks for posting in our business forum.

 

Can you give a screenshot of the LAN interface? Would like to see the LAN interface.

Is there any ACL which I asked multiple times?
