There appears to be some problem setting up Comodo with local proxies. I have setup Comodo/Proxo to try to help:- First you must set Comodo to settings shown below, to stop Comodo reverting back to "open" rules
Next we need to set the rules for Proxo / browser (example is with firefox). Below are the rules once completed,.. I will give a fuller description next.
To explain the rules that need to be entered, I will first shown (pic) the first rule needed for firefox, you will then understand the format of how I am writing the rules. Firefox: Allow TCP in : Destination IP 0.0.0.0 : Destination port Any
Here are the rest of the rules required: Firefox: Block TCP out: Destination IP 127.0.0.1 (exclude, ie NOT the choice below: see pic): Destination port ANY Firefox: Allow TCP in/out: Destination IP 127.0.0.1: Destination port Any Proxo: Allow TCP in: Destination IP 127.0.0.1: Destination port 8080 Proxo: Allow TCP out: Destination IP Any: Destination port 80 Proxo: Allow TCP out: Destination IP 127.0.0.1: Destination port Any (This setup will allow only connections to remote port 80 (HTTP), if you want to connect to HTTPS(443), then add a rule for proxo:- Proxo: Allow TCP out: Destination IP Any: Destination port 443) I do have in place a rule to allow outbound DNS,.. but this will only be needed if you have the windows DNS client disabled. .
