Hello,
Let me start by telling I'm a complete beginner, but I've tried reading posts on this forum, YouTube, Googling etc. to find an solution, but I'm stuck.
I have an static IP from my ISP, it's a /30 subnet, so I only have one IP for my WAN and a GW. I think I have assigned it correctly to my WAN port (Fa4), and I have created a DHCP pool and assigned Fa0 to VLAN 10.
Problem is that I can't get an IP assigned to my laptop which is connected to Fa0, but if I do an ipconfig /renew, I can see an ARP for a few seconds, but my laptop still has an 169.x.x.x IP-address.
The other problem is that I can't ping outside to the Internet.
I'm sure I have made a rookie mistake, but I can't for the sake of me, see what. The IP 200.50.70.10/30 is just an example and not my real IP-address.

Thanks, this worked, but I also found out that I needed to tag my traffic with a specific VLAN, so I had to create a subinterface on Fa4, change the routing to this, and now everything works!
Thanks all. Have a great day.

Hello,
indeed certain ISPs require specific VLAN subinterfaces. Which ISP do you have ?
