My ISP gave me a /27 network with 29 IPs and I have DSL with a router that my ISP put on my premises. ASL is setup with 3 NICs and I want to setup a DMZ using one of those NICs. I want to be able to use all of the public IPs in my DMZ. I read through the older FAQ and searched the message boards and learned that if I could obtain a small network (/30) from my ISP I would be able to setup a transfer network since I have control of my router.
Unfortunately, my ISP would not give me that small network to setup a transfer network. [:(]Ps.
The router my ISP gave me is a Netopia Cayman 3500 series and reading through it's documentation it appears that it can be configured as a bridge. Additional searching through the forums here seems to mention that I could configure my router as a bridge which could allow me to use my public IPs in my DMZ without having to split it up.
So would any additional configuration beyond setting it up for bridge mode be required on my router? Will I need to add a route to the router to send my /27 network to my ASL box?
My /27 is 67.x.y.130-158, mask is .224 and the gateway is .129
This is what I have so far:
Code:
------------- --------- /----
|ISPs Router|67.x.y.129 67.x.y.130| |192.168.0.1 /
| |--------------------------| ASL |-----------/ LAN
| Cayman | | | \ 192.168.0.0
------------- | | \255.255.255.0
--------- \
67.x.y.131| \----
|
|
|
/ \
/ \
/ \
/ DMZ \
----/ \----
| 67.x.y.132 |
| 255.255.255.224 |
So to summarize, I want to be able to use my official network in my DMZ but my ISP will not give me a transfer
network so I want to know if I setup my router as bridge what additional configuration if any, is required to make
this happen? I do not want to use Proxy ARP and split up my official network therefore losing IPs.
Thanks in advance for any and all assistance in this matter. [:)]
