Cisco RV042G DMZ for WAN 2?

[harleyjamesa]

Hi, I run my business network on the 192.168.x.x range with a server set as 192.168.2.4 statically. The router is currently connecetd to two DCHP wan connections from my ISP, I'm on a residential consumer plan. It has defaulted to loadblanacing with the second WAN however I want to have the second wan's public IP be used by my server and only the server however I wish for the server to still be on the lan so I can use HYPER-V's brided network connection feature to run VMs on the lan, and I would like their wan connection to be from wan 1... as for the entire lan except the server at

192.168.2.4 Is this possible, I can't seem to get the 1-to-1 NAT to do it?

Dear Harley,

Thank you for reaching Cisco Small Business Support Community.

One to one NAT would be an option, same and most prefered in my opinion a Port Forwarding configuration since it just opens specific service(s) on the server from the outside.  The problem I see here is the dynamic WAN IP addresses you get from your ISP that if you can at least get the desired one assigned statically would solve the problem, otherwise I see no way to access the server form the internet since its IP address is unknown by the remote client or it just changes all the times.

So you can configure the let's say Port Forwarding following the below document, p. 44, but how do you access to the server if we do not know the dynamic IP address your ISP is giving you at a given time.  I suggest you to contact your ISP and figure out if they can give you the WAN IP's so you can assign them statically to the WAN ports, or find out if by any chance they assign your WAN connection the same public IP's everyt time eventhough they are not typed in the router and figure out what they are so you can use them to access the server remotely using that IP address.

Jeffrey, Thanks so much for the reply.

I should mention that I'm using a dynamic dns service to try and make up for the DHCP IP my isp gives me, so I just type server.mywebsite.com to use it's services. It runs as a process in windows server and is always up to date within 60seconds, so I can guarentee this hostname will map to the IP, would that help with routing at all?

I just had one question for the port forwarding. The settings don't seem to be able to specify WAN1 or WAN2, Does it do both? If so this is not quite the solution I'm looking for, would it be possible to forward ports from only WAN2? That would solve my problem.

Hello Harley,

The dynamic DNS should take care of the IP routing issue.

After going through out the RV042G admin guide I see no way to address the traffic to/from a particular LAN port to/from a partuclar WAN port, the WAN load balance is applied to all traffic. The RV016 has a "Protocol Binding" intended for this matter for unfortunately not available on the RV042G as of the admin guide.

I'd suggest you to get in touch with the Small Business Support Center just to make sure there is no way around your request;

When you port forward on the rv016, I recall it was from both WANs automatically.  If you don't want it forwarding from WAN1, I suspect you can just not use port forwarding and put in a static rule for WAN2.

And the protocol binding that's in the rv016 was also available in my v1 rv042.  I suspect it's possible to do in the G version as well.
