VPN one way ping

Hello
I have configured routeros to connect to a sonicwall firewall vpn. The remote peer is established and the SA’s are installed and the policies are dynamic. Problem is I can ping from the Sonicwall to the private network on the routeros but cannot ping from routeros to sonicwall

Local Network 192.168.169.0/24
Remote Network 10.1.1.0/24

Thanks

If sonicwall has the same structure as MT.

I suggest you shutdown the firewall for icmp in sonicwall input chain.
