Here's my conundrum: I'm coming over from using an RV320 router from Cisco and had previously used WAN1 to connect to an ISP's given static IP:
IP: 215.114.xxx.xxx Sub: 255.255.255.224 Gateway: 215.114.xxx.xxx LAN setup: 192.168.1.x 255.255.255.0 Gateway: 192.168.1.1
This is simple on the RV320, you just enter these settings for Wan1. My problem is, when using the CLI for the 890 router, it seems like you almost need to use two fast Ethernet (wan ports) to do the same task. I can set the ip on fa0/0 to reflect the LAN network (able to ping internally) or the WAN (able to connect to ISP) but can't seem to accomplish this with a single WAN port as before. What am I missing here, how can I assign the router an internal IP without using a WAN port, and then just connect down to my LAN using the switch ports?
Edit and solve:
It looks like I've managed to sort through what my issue was, so I'll post for anyone that might be interested. It was a combination of two problems A) My DHCP pool was not accessing the correct router address I've since changed it to:
and B) I did not have VLAN1 up. I would love to here if anyone has any advice for my setup, but it looks like my initial question is solved.
