I appreciate everyone's help! Thank you, thank you, thank you!

By them, are you referring to the ethernet switch?

The 172.27.35.1 is the LAN IP address of the Ooma router. Your Linksys router has a WAN IP in the 172.27.35.x subnet. You need to figure out that IP and forward a port - say 9091 - from the Internet on the Ooma to the Linksys router's 172.27.35.x. Then you need to forward port 9091 on the Linksys to the 192.168.1.147 and port of your camera.
Makes sense, though I'm at a loss for how to figure this out. I know how to see all connected devices on my router, but I don't see anything similar on http://setup.ooma.com/. I do see, under the internet tab, "Static IP options" with spots to indicate static IP addresses for:
IP Address
Netmask
DNS Server 1
DNS Server 2
Router Address

Could I specify the router IP address there? Otherwise, do any Ooma users know where I can find the router's internal IP address on my Ooma setup? Or is there a downloadable tool I can use to figure it out?

This called double NATting and can cause some odd network issues. It should mostly work, however. A better solution would be to use your Ooma config interface to set the Linksys router as a DMZ host. This means your Ooma just passes everything from the Internet that isn't related to Ooma to your Linksys as if the Linksys were connected to the Internet directly.
In the Ooma setup/Home Network Settings I see a spot to enter a DMZ IP address. When I go to the help section, Ooma says:

This option allows you to automatically forward all Internet traffic received on the INTERNET to a specific, pre-configured IP address on the HOME port. The DMZ option is often used when you use applications or servers on your Home network which must bypass the firewall of the Ooma Telo.

NOTE: Use of the DMZ will disable the firewall function of the Ooma Telo and will expose your internal network to unwanted and, in some cases, malicious forms of traffic from the Internet.
Is that what I'm looking for? And could I use any IP address in this field or do I have to know the LAN IP address for my router?

As for the ports you investigated being closed, those are likely the ports that Ooma is connecting to at ooma's site, not inbound ports for your network. Still, I wouldn't use common ports like 443 because those are the first ports that people scan for.
Understood.

So, big question: Is there an alternate setup/configuration that would be easier to manage and also increase my security? Or would a VPN, etc., still require me to solve these connection problems first?
