SonicWALL - Cannot Connect With VPN Clients Through SonicWALL

I have a SonicWALL SOHO with a Site to Site VPN to my office.  That works fine.  However, I cannot connect with VPN clients to other VPN devices.  I try the SonicWALL GVC to a SonicWALL and I've tried native VPN clients (Mac and iPhone) to connect to a Meraki VPN.  Both use port 500 and both time out.  When I do a packet monitor packet capture, the UDP port 500 traffic is being consumed by the SonicWALL.  Any ideas?
