Hi everyone! I've finally landed my first job as a network engineer in a small company. I can't understand one thing regarding the uplink. While I was preparing for CCNA the main connection to the internet was via the firewall. In almost every network I have here the Internet goes directly to the switch and then to the firewall. I totally don't understand this design concept. Could somebody explain it to me in depth? I am very curious. When I asked my colleague he said:"This is how the network was built in the past... but why?
Thanks in advance,
Patryk

check more details of your topology.
It could simply be that the FW is not physically between the ISP and your network, but logically
just like the "router on a stick" it can be a "firewall on a stick"
e.g. the ISP is connected to the switch, this connection is forwarded by a vlan to a subinterface on the FW as outside link
same for inside vlan(s)
