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:
216.113.118.231
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.

I think the RV320 is just confusing the issue as there are two "WAN" ports. You had the ISP settings on one of the WAN ports, and the LAN settings on the LAN ports. Now you have a router where this distinction isn't necessary. Use fa0/0 as the WAN ports, then create a VLAN that contains all the other ports, and assign the LAN settings to the VLAN (this was done automatically on the RV320) – Paul – 2015-08-13T03:41:42.920
@Paul Okay, how do I go about setting the lan settings for, I'm assuming the GI0-8 ports? Is it a matter of assigning the built switch ports to, let's say VLAN 3, and then creating a DHCP pool? – ParanoidPenguin – 2015-08-13T03:46:31.010
Yeah, that is right - though normally they default to vlan1 out of the box. Can you paste the config somewhere? – Paul – 2015-08-13T03:47:39.467
@Paul I've posted a quick configuration that I've come up with, as I'm no longer with the physical device. – ParanoidPenguin – 2015-08-13T04:15:26.417
@Paul I posted a small edit above, showing how I came to resolve the issue. Your advice was really helpful, I wish you had stated something as an answer, so I could give credit where it is due. – ParanoidPenguin – 2015-08-13T04:44:43.877
1No problem, though if you have identified the answer, please add it as an answer, and then accept it. That way it will help others. – Paul – 2015-08-13T05:12:33.943
