Your internal lan cant have a public address as a gateway i think , if the lan needs to talk to the outside, one way is to use masquerading at 192.168.100.100 so the gateway needs to be 192.168.100.100 i guess ...
Correction:
You can certainly have the LAN subnet 192.168.100.0 have 59.144.168.226 as a default gateway.
I have SCO Unix. I have 2 routers. as it is now, when someone telnets to UNIX and goes through router #1 everything is fine. The users who go through router #2 can not connect at all. I talked to CISCO and they said I need to set up a second Gateway on UNIX. They said what is happening is that... (1 Reply)
ok i configured my gateway and IP address(es) using ifconfig and route.. but how can i bind unique IPs to users ? (im using FreeBSD 4.2 RELEASE #3) (9 Replies)
Can anyone help with the following;
I am working on a unix server (Apple OS X Server). We have two network cards in the server. Both cards are on different subnets i.e en1 is on 192.168.10.10/24 and the built in ethernet is on 10.10.150.10/24. From a computer plugged into en1 (and set to ip... (5 Replies)
Hello Friends
I have two network cards
eth0 192.168.100.1
eth1 10.0.0.1
There NIC connect with diff. LAN
I want to make my Linux machine as a Router, Please tell me
using
IPTABLES command
ROUTE command

Hey guys,
I needed to add a route to my routing table and I got it to work but on reboot it gets removed. Anyone know what file I can add this route to so it stays on the machine after a reboot? (9 Replies)
Hi all,
I am confusing with routing table, i use linux and iptables.
i have 1 internet gateway, and 1 router for VPN.
here is my network.
eth0=192.168.0.1
eth1=192.168.100.1
192.168.0.0/24 --- eth0(Linux Box)eth1 ---(DSL)---Internet

I have a series of new machines that are internet facing (have IP's that are accessible via the 'net) and it has internal facing interfaces. I need to be able to communicate back to the internal network to a specific server which processes monitoring and e-mail traffic. I've been told that I should... (3 Replies)
Hey all you *Nix Gurus...I got a relatively simple one for ya.
I just cloned an AIX 5.3 server without copy over the Network info. However, now I need to update the routing table on the destination server so that it mirrors the source. Aside from painstakingly, manually updating the ODM using... (1 Reply)
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
