We have a Guest network, and I’d like traffic coming from this network going out to the internet to use a different public IP than my internal networks. The network has Web Filtering enabled in transparent mode.

XG is able to reach the internet because rules for him are already opened. You do not need to create rules.
I have the same installation as yours at home and you only need to create rules to allow traffic from internal to wan zone (network-user rules).
Security: Comparing NAT, Static Content Filtering, SPI, and Firewalls
1. Enter Dashboard and assign Public IP of a NAT device to one of the existing filtering profiles (to use NAT DNS you must have more than 2 profiles).
NAT – Network Address Translation
Many security problems (attacks) were caused by bugs or unplanned protocol operations in the software implementations of Internet hosts. Fixing the problem would have required a way to control the Internet traffic to which the end hosts were exposed. Today, this is provided by a firewall, a type of router that restricts the types of traffic it forwards.

Now all traffic should be going to your proxy server on port 3128. However, if you want to filter https then this is where it gets complicated, you have to enable SSL Man In the Middle Filtering and create Certificates and even after that you may get connection errors and all sorts of issues.
The Virtual Server option gives Internet users access to services on your LAN. This feature is useful for hosting online services such as FTP, Web, or game servers. For each Virtual Server, you define a public port on your router for redirection to an internal LAN IP Address and LAN port.
As many of these posts are, this is in part to document the process for myself. However, for anyone running IIS as their web server (such as for Windows Home Server or Windows Server Essentials),
