Hello, I'm installing a Mikrotik Router for an ISP. I need appropriate firewall rules. Can I use the firewall examples listed on the wiki ? or they are outdated? http://wiki.mikrotik.com/wiki/Firewall
How you secure your router is entirely up to you. Mikrotik only provides means for doing that and they are more than enough. Wiki is quite clear and definitely not outdated. Firewalling is basic networking and not very MT related
