Setting up Linux as an Internet gateway is not difficult to do. A Linux gateway allows two or more computers to use the Internet at the same time. While doing so, only the gateway's IP address will be visible on the Internet. The rest of the computers will be hidden behind the gateway. This is called IP masquerading A computer needs to know the address of at least one gateway in order to connect to another network, this is called the Default Gateway. Whenever a computer tries to connect to a machine on a different network it will connect to the default network gateway and then the network gateway will route the traffic to the righ

I don't want to issue a call to the shell or read a file. There are ioctls for adding and deleteing routes (SIOCADDRT, SIOCDELRT) and I've found on reference to getting routes (SIOCGRTCONF) but it seems that the version of the kernel I'm using doesn't support SIOCGRTCONF A default gateway is a remote host or router that your Linux host forwards traffic to when the destination IP address of outgoing traffic does not match any route in your local routing table. Configuring a default gateway on CentOS is quite straightforward. If you wish to change a default gateway temporarily at run time, you can use ip command This is OS specific, there's no unified(or ANSI C) API for this.

If you require DNS for your temporary network configuration, you can add DNS server IP addresses in the file /etc/resolv.conf. In general, editing /etc/resolv.conf directly is not recommanded, but this is a temporary and non-persistent configuration Normally, a Linux system only has one routing table, in which only one default gateway can make entries. With iproute2, you have the ability to setup an additional routing table, for one thing, and allow this table to be used by the system based on rules, for another The ip command is a powerful tool for configuring network interfaces that any Linux system administrator should know.

If you are using another Unix-like operating system such as BSD or macOS X (whose foundations are based upon BSD), the ip command may not be available; however the same, or very closely similar, functionality can be achieved using the route command. For instance, this Linux ip command: ip route get 74.125.226.35...which outputs Configuring IP Forwarding. For your Linux server to become a router, you have to enable packet forwarding. In simple terms packet forwarding enables packets to flow through the Linux box from one network to another.

Having such a file allows DHCP server to keep track of all IP address leases even after the reboot or power failure

22.4 Configuring a Network Connection with YaST. There are many supported networking types on Linux. Most of them use different device names and the configuration files are spread over several locations in the file system Now that we've found the default gateway, we tell the system to delete it with: ip route del default via 192.168.1.1 Adding a new gateway. And now comes the easiest part of all. With the local default gateway deleted, set the VPN gateway (again, that's 10.1.1.1 in our example) as the new default with: ip route add default via 10.1.1.1. That. This is often called IP masquerading. The Linux OS interface which enables one to configure the kernel for masquerading is either iptables (Linux kernel 2.4) or ipchains (Linux kernel 2.2). The gateway Linux computer will need two IP addresses and network connections, one to the private internal network and another to the external public internet

Basically dhclient appears to only set the default gateway when routers are provided by the server and when a current default gateway is not set. so, as doon mentioned, you can add a route del default gw to your network configuration or you can do this manually (or in your own script) before dhclient is called Linux(Centos) Gateway Server Configuration: Step by Step Procedure 8/05/2013 08:27:00 PM If you're trying to set up a home network, you probably want to set up a permiter facing computer connected to your DSL/Cable modem, and then put all of your computers behind that firewall box to keep them safe Add a secondary IP to Linux Add a second temporary IP address.

The linux ip command is similar to ifconfig, but more powerful and is intended to be a replacement for it.With ip you have the advantage of performing several network administration tasks with only one command. ifconfig is one of the deprecated command within net-tools that has not been maintained for many years According to your routing table the IP-Network for the gateway (10.132.81.161) is connected via NIC eno50.But the route-setup command points to NIC eno49. Maybe you should just omit the dev eno50 in your route command or change your ip configuration so that 10.31.181... is configured to eno50 instead of eno49 No change - similar results - missing the default gateway hop on ingress traffic. I suspect it must be something to do with the vlan since the default gateway is one of those enterprise managed switches (think Cisco/Juniper - this one's an older Foundry) - quite possibly the switch is changing between routed and bridged mode or something based on which way the packets travel But there are also good reasons why you may want to set a static IP address in Ubuntu - from improved security, to gaming, faster Internet speeds, and port forwarding.
