Issues with site to site vpn sonicwall pfsense

alex1002

Good Day,
I need some help:
I created site to site vpn

I can ping the network on the sonicwall side using the IP (dns names do not work). I cannot ping the pfsense network from the sonicwall side.

Would the NAT/BINAT translation affect anything if I change on the sonicwall side?

Did you allow traffic in on Firewall > Rules, IPsec tab?

When it comes to NAT, the sonicwall doesn't know about your actual internal network. So their tunnel P2 is built to the NAT network and on the sonicwall side when they try to ping the pfSense side, they ping the NAT network addresses instead.
