I have an issue with routing public IPs on the RV042G. I have been able to route the IP's in a couple of different ways, but there is always a nagging problem. Any help or suggestions would be appreciated.
I have a PPPoE Business Class account with 5 routable public IP's. I would like to route the IPs and manage the private network using the RV042G.
Here is what I have tried and the problem that arose: 1) I used 1:1 NAT and the servers responded with no issue. This would be a workable config however I use Kerberos for single sign-on for my clients. To use this security protocol and bind the clients to the server, I must use a public IP on the server machines. In this scenario however, everything else worked fine. 2) I then tried using the DMZ and putting the servers on the DMZ port with a public IP entered in the network config of the machine. That even worked fine and I was excited until I noticed that the servers were reporting the public IP assigned to the DMZ port as their IP when they sent mail. I then ran a test and that is the case. The servers - each with a public IP - are reporting the IP of the DMZ port. I can't have that because the mail servers need to announce a correct IP so the reverse lookup will match. Once again, a little gnat gets in the soup.
I would like to configure a way to run a public network and a private network using this product because of the firewall. The DMZ had a range option in the same subnet as the WAN, BUT it requires a Static IP connection type on the WAN and I have a PPPoE. PPPoE is a strange animal. When you connect, the ISP provides 2 subnets using the same IP octets for the addess. Like this:
12.34.56.78
255.255.255.255
12.34.56.78
255.255.255.248
The first set shows on the summary page as the IP of the WAN - so I entered the second set in the DMZ and it will route everything as expected. The major issue here is that ALL machines on the DMZ announce the 12.34.56.78 address to the internet. I need them to announce 12.34.56.79, 80, and so on.
Any ideas? I can make this work in other ways, I just want ideas on making it work with a RV042G only.
