Hello all,
I have recently purchased a RB2011UAS-2HnD-in, and I am having troubles with the DHCP-client.
My ISP uses a DHCP server to assign IPs, but I am unable to acquire an IP with the RB. The routere being replaced is able to get a dynamic IP from my modem without issue. If I plug my modem into the old router, and connect ether1-gateway to a lan port on the old router, the dhcp-client on the RB receives an IP as well as the DNS information required and serves an internet connections to clients without an issue.
So as it stands, it would seem that my dhcp-client is configured correctly, but I am missing a detail somewhere that is keeping me from receiving an IP from the ISP
Thanks.
Try this
Click on the interfaces and select the Ether1 (in your case what ever it is) at the bottom you will see a drop down menu with by default selected “arp” change it with proxy-arp and then try it
Try powering off your modem and then connecting your routerboard, then power the modem back on. Sometimes ISP’s modems bind to a mac address and cannot release until rebooted. Let me know if this works for you.
Does the ISP possibly limit the IPs provided per line? If you want to test that possibility then temporarily set the routerboard WAN MAC address to the MAC address of the WAN port on the original router and see if it can then get an IP via DHCP.
I resolved my problem by cloning my former router’s IP to the current WAN interface.
Thanks anyway.
