I noticed from my router settings that there is a firewall enabled. This is in addition to my zonealarm firewall. What's the difference between those two firewalls and are they both necessary?
Apologies if for this naive question.
Fixed! Go to the fix.
@davycrockett, welcome to the forum. You only really need one Firewall and for me that would be the one in the router. Zone Alarm is just wasting your clock cycles, and re-doing work that is already done at the router Having said that if you feel more 'secure' running both then why not.

Router firewalls are generally hardware based whilst Zonealarm’s will be software. I would keep both running. See here for more detail. https://www.nortonsecurityonline.com/security-center/how-does-firewall-work.html
Moderator's note by Dick (Strat): Link fixed.
As one is hardware and the other software based there will be no conflict. I can't work out why the link doesn't work. If you do a Google search for 'How does a firewall work' it will direct you to this address, where it will work.

There was a space at the end of the URL @Baldrick1. It happens quite often with posted links.
