What my network looks like:
NET
|
NAT/FIREWALL(2.1.24.34)
|
-------------------
| | |
2.1.24.35 2.1.24.36 2.1.24.37
There is no DHCP, I don't think it is possablie to do this but I want to
install a bandwidth monitoring program on 2.1.24.35. That will monitor
all traffic going through 2.1.24.34. I installed bandwidthd but it's
only local traffic I can't get all traffic through 2.1.24.34. I think I
need to but a middle man between NET and 2.1.24.34. I don't have any
more ips to use. 2.1.24.34 is a firewall like netgear, linksys, etc
setup with NAT.
What I see is I need to replace the NAT with something where I have a
shell. I don't think it is possible with the current setup, but figured
I would ask. Thanks for any help.
