IP Sec Tunnel Interface is UP, but i can't do a ping to remote pc

[ergalez]

Hi, I have 2 fortigates a 60E and a 20C I have established the IPSec tunnels for site-to-site vpn. The tunnel in both fortigates appears to me to be up, but I cannot ping between the lan networks. I have set the static route and added the access policies. I don't know what else to do. And if I check the IPSec monitor, I see that there is incoming and outgoing traffic.

Hello,

You can try disabling the NP acceleration for IPSEC VPN phase 1 on the 60E, and perform the test again
