We have a Cisco RV016 that we have used successfully for several years to route email and other traffic from different ISPs. We are in the process of changing the name of the firm and have acquired a new domain name, yyyy.com, that will be used among other things for email directed to our existing exchange server. Email currently coming to our original domain, xxxx.com over our fiber connection will still be received by our Exchange server for the foreseeable future. We successfully setup and tested the new email domain on Exchange using the RV016 on a DSL connection that is now disconnected. We now need to move the new email domain to our existing fiber connection but we are having problems configuring the rv016 to direct all smtp traffic to our firewall. Our ISP has provisioned the data port on their managed router with the following block of addresses:
Lan: xx.xxx.xxx.176/28
255.255.255.240
From this we surmise that we have a block of 14 addressable IPs with a gateway at xx.xxx.xxx.177.
From the block we have assigned
mail.xxxx.com to xx.xxx.xxx.178
mail.yyyy.com to xx.xxx.xxx.179
On the RV016 we configured WAN1 as follows:
Static IP
Wan IP xx.xxxx.xxxx.176
Mask 255.255.255.240
Gateway xx.xxxx.xxxx.177
DNS Servers provided by ISP
We also set Port Forwarding to send all smtp traffic to the Lan address for our firewall and bound smpt traffic from Wan1 for range xx.xxx.xxx.78~79 to Lan address for firewall. Acess rules are set to allow all smtp traffic on Wan1 to firewall.
For the record I am not an IT guy by trade but we have a fair amount of networking experience. This routing issue has us stymied. What are we missing?
