How to route static ip block through router to virtual machines in VMWare.
As a network administrator, I want to route traffic directed to my static ip addresses to virtual machines running on a VLAN using Virtual Switch Tagging.
- My MTA running on a virtual machine on a VLAN can deliver mail outside of my local network.
- My MTA running on a virtual machine can recieve mail from a MTA that is outside of my local network.
I already have a static ip setup to allow a VPN connection to my router and I have done this a couple of ways, both of which work.
Configure my router with a static ip from my static ip block.
Counfigure my router with a local ip and configure my Comcast Business router to use NAT to translate an external ip to my internal router ip.
My problem is that on my LAN, i configured a VLAN that is effectively my DMZ. From my router, I use NAT to translate an external ip a host on my VLAN and this works fine. However, I can't configure the Comcast Business router to route an external ip to my router.
External CIDR block: a.b.c.94/29
Comcast Business Router ip: a.b.c.94
Static Block: a.b.c.93 - a.b.c.89
Router WAN ip: a.b.c.93
Router LAN CIDR: w.x.y.z/24
VLAN CIDR: h.i.j.k/24
VLAN Gateway: h.i.j.1
With this setup, NAT is configured on internal router so a.b.c.89 translates to h.i.j.100 with no problem from LAN, evidenced via ping. When going outside my network I can't ping a.b.c.89. However, I can ping my Comcast Business router at a.b.c.94, and I can ping my internal router at a.b.c.93. So it seems that I need to route external ips from my Comcast Business router to my internal VLAN host. I am at a loss on how to do this.
