Failed resolving dest MAC for default gateway:11.11.11.1 on port 0 ===== DUT side : ----- CONFIRMED that DUT (Linux Router) replied ARP properly as follows: [root@sang ~]# ifconfig enp1s0f0 enp1s0f0: flags=4163 mtu 1500

You can issue tracert 8.8.8.8 from your PC and find out the next hop IP address, that would be your next hop (gateway IP address) IP address, after that, issue command arp -a, and see that IP address mapped to which MAC address and that MAC address is the next hop (gateway). Following is just for example. Jun 14, 2007 · How Not to Use Default Gateway on VPN (PPTP) in Mac OSX Thursday, June 14th, 2007 · 4 Comments Well, after search­ing for hours and hours, I have final­ly found a solu­tion to a small but trou­ble­some prob­lem. EDIT: This has been resolved by setting the default gateway on the Mac server to 192.168.1.254 Thus leaving everything on the network as it was before. but to get the Mac server to use the other link for rsync I've added a route to the Mac server to route traffic to the rsync server through the second gateway. May 06, 2007 · The switch sends all off-network IP traffic to the primary default gateway. If connectivity to the primary gateway is lost, the switch attempts to use the backup gateways in the order that they were configured. The switch sends periodic ping messages to determine whether each default gateway is up or down. The closest router that is known is the default gateway (192.168.1.1). To be able to send data through the router, the first host needs to know the MAC address of the router. The host checks the ARP cache, and if the MAC address for 192.168.1.1 is not there, it sends an ARP request for the 192.168.1.1 IP address. Mar 04, 2011 · joe$ ip route | grep default default via 192.168.1.1 dev eth0 proto static; In this example, again, 192.168.1.1 is your default gateway (router) IP address.

The gateway address must be configured on each host. The network host IP interface binds the gateway address to the MAC address of the physical gateway by broadcasting IP datagrams and caching the MAC address of the reply from the gateway in an ARP table stored on the host. The gateway address may be added manually.

Default Server mode allows the AT&T provided gateway to forward all externally initiated IP traffic (TCP and UDP protocols only) to a specified device (default host) on the LAN. A device configured for a default server will continue to receive a LAN IP address, instead of being assigned a WAN IP. For MAC OS: Step 1. Click the Apple icon the click on System Preferences . Step 2. Click on Network. Step 3. Click on the Configure IPv4 field, and select ‘Manually” Step 4. Input your IP information (Router is the Default Gatway address) and click Apply To delete the current gateway from en0, run: sudo route delete default -ifscope en0 This will delete the default gateway from en0 while leaving any other defined routes intact. Add the new gateway. To add the new gateway to en0, run: sudo route add default 192.168.1.1 -ifscope en0 Replace 192.168.1.1 with the IP address of the actual gateway. A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communication on the physical network segment. The serial number is on the back panel of the appliance. If you do not have easy access to the back panel, you can get the appliance’s serial number by logging on to the LOM port.
