If it a block of 4, then the other usable IP is used by the Comcast device and is typically one above or below your free IP address (so either 177.231 or 177.233).  So you would set the SW to use that IP instead of the 177.232

Within the constraints of the number of IP addresses above, your WAN IP should be and the other address is in the Gateway block.

Either will work if in your assigned IP block from the ISP

Neither is working.  Router is in bridge mode.

Your iSP machine is.a modem. Make sure your router has assigned the correct external IP address
Please give us the exact information Comcast provided you, while filtering out the first 2 octets like you've been doing.

My guess is you should be using 177.232 or 177.233 as your IP based on what you've posted.
