Thanks for the response.
I have started with the router set to its default configuration then exported the configuration and attempted to modify it to change the wan port from ether1 to ether5. The modified configuration is below.

I used the command "/system reset-configuration no-defaults=yes skip-backup=yes run-after-reset=default-mod-wan5.rsc" to load the modified rsc file. After loading the configuration the WebFig "Quick Set" page shows the "Configuration Mode" is Bridge, under "WAN" it shows only the MAC address of ether1 rather than ether5 and under the heading "Bridge" Address Acquisition is Static.
ether5 has been set as a dhcp client and is getting IP's from the CPE connected to it
[admin@MikroTik] > /ip dhcp-client print
Flags: X - disabled, I - invalid
# INTERFACE USE ADD-DEFAULT-ROUTE STATUS ADDRESS
0 ;;; default configuration
ether5-gateway yes yes bound 192.168.221.52/24

Ether1 is master, ethers2-4 are slaves to ether1 and the router is giving out dhcp but there does not seem to be any connection between ether5 and the other ports.
Any suggestions of how to proceed would be appreciated.
