I believe I have things set up correctly and working in bridge mode. My modem is performing only the modem function, and no routing functions. The router now performs the PPPoE, DHCP, NAT, and firewall functions. The configuration changes are...
Actiontec DSL Modem - Change from "PPPoE" to "RFC 1483 Transparent Bridging"
Linksys wireless router - Change from "Automatic Configuration (DHCP)" to "PPPoE" and enter username/password for the internet service provider. DHCP, NAT, and firewall are enabled by default.
I turned the LMCE firewall off to allow it to communicate with my wireless router on the external LAN. My VOIP works, as does my laptop orbiter. General download speeds are the same, but websites seem to load much quicker. Progress is good!
