help Configure NAT Overload on home lab
Hi everyone. I have trouble configuring Nat overload on my network.
Ok..... this is what i have.... ( i will use fake IP address for secuirty)
When i go to whatismyip.com it tell me 184.108.40.206
I have a netgear cable/modem that has a wan Ip address of 220.127.116.11
this ip addressing scheme has a 18.104.22.168 mask.
I will be configure NAT on router 1...
this is what i understand. when i use the command...
ip nat inside source list NAT_ADDRESS interface e0/1
now so this is where im confused.. Do i make the ip address on e0/1 22.214.171.124 becuase this is my WAN ip address, and since the ip address on my computer will bet translated to whatever is on ether0/1... and thats what the ip address i use to access internet?
is that correct... IF not what should i have my e0/1 ip address configured at..
Also i spoke to my ISP and they are only leasing me one ip address...
also my netgear cable/modem is a DHCP server, and it is giving ip address to my host..
if this is confusing. I am making a network diagram right now so will i can show yall how i am hooked up...
basically i dont know what to set my e0/1 ip address to..???
Heres my setup
the modems IP and internet IP is stated above in the post.
what do i set my e0/1 ip address to be so that i can access the internet.?? to my understand should my computer be translated to 126.96.36.199 because this is what the isp give me... am i correct ?
when my pc is plugged into my netgear. i am getting a Lan Ip address of 192.168.0.13.
yeah that is what i did. I set up my e0/1 to recieve an ip address via DHCP from netgear.
but i think its passing out lan ip, not wan ip address.
So yes, i belive my Netgear is already doing PAT.... I will see if i can disable that.
I also have this Aris (or whatever its called) cable modem that i could use. I dont believe that is runnning PAT...
DANG>>> i forgot to mention... The netgear is connected to the aris i belive by a coax cable...
the coax cable runs into my house, then it has a T connector, and it splits to the aris and then then the netgear..
So i believe that the Aris doesnt run Nat, and the Netgear does..
again, ill see if i can disable it, but i didnt see the option in the netgear config (when i type 192.168.0.1 in the web browser)
No. Mike... My ISP said they Dynamically give me an ip address. but it has been 6 months and it hasn't changed yet.. so i believe it wont change on me.. even when the lease expires and a new one is updated it is still the same ip address. so i dont think it will change.
hope this helps
