Hi. I’m looking for a bit of guidance on setting up a FreePBX system with two NICs on the same subnet with eth0 as the gateway (WAN) and eth1 as a DHCP server for the phones (LAN). From my testing, the DHCP server will not service requests when the gateway is on the same subnet, even if different NICs are used. More specifically: eth0: static IP: netmask: 24 gateway: eth1

The default Lease Time is 1440 minutes (24 hours). The time length of the lease can range from 1 to 9999 minutes. Select the gateway IP address that will be assigned to DHCP clients using the Gateway Preferences and Default Gateway fields. The Cisco IOS DHCP server is a full DHCP server implementation that assigns and manages IP addresses from specified address pools within the router to DHCP clients. The DHCP server can be configured to assign additional parameters such as the IP address of the domain name system (DNS) server and the default router. The router supports an individual server for each Ethernet-like interface. The MikroTik RouterOS DHCP server supports the basic functions of giving each requesting client an IP address/netmask lease, default gateway, domain name, DNS-server (s) and WINS-server (s) (for Windows clients) information (set up in the DHCP networks submenu) If the DHCP server is the router in a small network, the default gateway usually points to the IP address of the DHCP server. In addition, a router that acts as the default gateway needs to maintain this level of routing knowledge to reach other remote network segments in the larger internetwork, so when you use the DHCP server as the default gateway, you may also need to take the performance into account. That seems to have worked. I left in one other line just to be sure there wasn't a competition between the two and intentionally switched the order of the primary and secondary NICs so that the one as default triggers last: # The secondary network interface auto eth1 iface eth1 inet dhcp up route del default gw ..**.254 # The primary network interface auto eth0 iface eth0 inet dhcp gateway 10 On Router (Default Gateway) page, add your gateways IP address and click Next. (Don’t forget to click on add button after specifying gateways address) 12. We have install the DHCP server role on our Domain Controller, so the wizard will automatically detect the DNS server’s address. The wizard asks for the credentials to use when creating this DHCP server. The default is to use your current login credentials. Click Next. The wizard displays a confirmation screen that summarizes the settings you’ve entered for the DHCP server. Click Install. The DHCP server is created. This might take a few minutes.

In WinXP the dhcp default gateway was correctly overridden by this manual setting. In Win7 it appears that the dhcp default gateway is retained and the manual one is added to the list so that there are two with the dhcp one having the primary metric. I have tried several ways to remove the dhcp default gateway such as, running the "route delete

The MikroTik RouterOS DHCP client may be enabled on any Ethernet-like interface at a time. The client will accept an address, netmask, default gateway, and two DNS server addresses. The received IP address will be added to the interface with the respective netmask. The default gateway will be added to the routing table as a dynamic entry.

How to find default-gateway assigned vi - Cisco Community

The default is None. Enable DHCP Client Enabling the DHCP client causes the wireless gateway to automatically obtain the public IP address, subnet mask, domain name, and DNS server(s). Most commonly, the DHCP client is enabled if the cable service provider automatically assigns a public IP address from their DHCP server. Mar 08, 2013 · To configure the DHCP default gateway option: Click Start, point to Administrative Tools and then click DHCP. In the console tree, expand the applicable DHCP server, expand IPv4, and then right-click Scope Options Click Configure Options, check 003 Router, type the applicable Server name and IP address, and then click OK. default-lease-time: number of seconds the lease remains valid if the client requesting the lease do not specify the duration. max-lease-time: Maximum number of seconds allowed for a lease. 3. subnet-declaration. The subnet declaration includes a range of IP addresses that a DHCP server can assign to clients. You can specify multiple subnets here. Jun 25, 2016 · How to change your LAN IPv4 Address including Default Gateway, Subnet Mask, DHCP Server and DNS Server. You can check the IP Address in Command Prompt using the command 'ipconfig'. Steps to do: Go capture DHCP offer packets and retrieve gateway; look for packet which is addressed to outer network (e.g. do arp request on each target IP address - if no answer you have probable mac address of the default gateway - you need to find IP address of this gateway (analyze arp packets, all packets, etc..) The default is port 67. The DHCP server transmits responses to the DHCP clients at a port number one greater than the UDP port specified. For example, if the default port 67 is used, the server listens on port 67 for requests and responds to the client on port 68.
