I have a 493AH board which I want to set up in such a way that I can have two parallel Networks on the same wireless network. That is i currently have my whole network behind a NAT/Router…I get my bandwidth on the fibre from the phone company. Everyone then receives a 10.100.96.0 to 10.100.127.254 IP using a subnet of 255.255.224.0. I want to also be able to provide an IP Adress Directly from the phone company to select customers.
Question 1. Is there a way to set up the port I have as my “wan” port and make it take in more then 1 IP from the phone company …Could that port deal with say 100 IPs from the phone company and then forwarad each IP and all possible ports 0 -65536 to a given IP on the other side of my NAT.
Example
telco Ip hitting 493Ah lan port 1= 205.111.111.111 / I want it to forward everything to 10.100.96.1
telco IP hitting 493Ah lan port 1= 205.111.111.112 / I want it to forward everything to 10.100.96.2
telco Ip hitting 493Ah lan port 1= 205.111.111.113 / I want it to forward everything to 10.100.96.3
telco Ip hitting 493Ah lan port 1= 205.111.111.114 / I want it to forward everything to 10.100.96.4
telco Ip hitting 493Ah lan port 1= 205.111.111.115 / I want it to forward everything to 10.100.96.5
Etc Etc Etc.
Question 2
Would it be better to have the end user receiver the telco IP as their static IP and just have both sets of IP ranges running through my network together. If so how would I set that up.
If all those IPs are on a subnet located on the ISP facing interface best practice would be to statically NAT them to customers. Alternatively, have the telco route those public IPs to you via your WAN address, in that case your router WAN address would be on a different subnet than the public IPs you want to issue to clients. You can then implement one of those IPs on your inside interface as the gateway IP, and hand the IPs to the clients directly. I do think it’s bad practice to run more than one logical network on the same physical broadcast domain.
Right now I have 5 IPs say 111.111.111.113 to 117 from the telco company they are given to me out of their Cisco router . I have lan port 2 on the 493Ah set up with the static IP 0f 111.111.111.117…and it is acting like a Wan port… that is I have a router set up in the 493ah Port 2 is the wan port and port 1 is the lan port all other ports are bridged to port 1…If i was to give a client on the other side of my NAT say IP 116 as a global IP for them how would I get lan port 2 on the 493 AH to pass that 116 IP to an IP on the other side of my nat.
I guess what is confusing me is I have all five IPS from the telco company showing up at/on Lan port 2 so how do I get lan port 2 on the 493Ah to distinguish and route IP 111.111.111.113, 114, 115, 116, to IPs on the other side of the Nat which would be say 10.100.96.1 , 2 , 3 etc etc
And If I NAT this wont there be some protocols that dont work for the end users it wont be the same as having a global IP from the Telco company
