I have a WRVS4400N and I need to use router mode to connect to our new ISP. The new ISP provides a Hatteras (HN 404) Ethernet WAN device with a gateway address (/30) and a subnet of 13 public IP's for our use (/28 subnet). I'm told that the HN 404 does not provide any routing itself as it is strictly a Layer 2 device. I have another Cisco router that I'd like to chain off the WRVS4400N and provide it one of these public IP's on one of the LAN ports and take a second public IP and create a NAT private LAN available from the remaining LAN ports and the wireless. I'm assuming that the ISP uses static routing for now.
Is it possible to use static routing from the WAN port to route the public IP's through to one or two LAN ports on the WRVS4400N and NAT one of those public IP addresses to a private LAN (ex. 192.168.1.x) that's available from remaining LAN ports and wireless on the WRVS4400N?
Thanks for any help!
