Thanks for your help redfive.
It would have been useful if I had a clear understanding of the architecture, but I have not been able to find entry level documentation.
I was able to achieve results after reading a few posts and understanding that the NAT table might have something to do with it.
By adding the interfaces to the “NAT Enabled Interfaces” list, traffic was flowing back and forth between vlans since the deault policy was “ACCEPT”. I had to restart at times, but after turning different things on and off, I was able to narrow it down to the NAT Enabled Interfaces. I had to had the 2 vlans I needed to communicate to that list, then use the firewall’s FORWARD chain to control the traffic.
Thank you again for your help.
