Re: Check Relay Agent IP address<br></font><br>Hi Billy<br><br>The dhcp server does this automatically. If a request comes in from a remote subnet, the dhcp relay agent adds in the gateway address as it forwards the packet. The dhcp server looks at this gateway address and automatically matches it with a subnet declaration for you.<br><br>There is no special dhcpd.conf configuration required. A subnet declaration is the same whether it is a locally attached or remote network.<br><br>regards,<br>-glenn<br><br>Billy Ng wrote:<br>> Dear All,<br>> <br>> Is it possible to check the relay agent IP before assign an dynamic IP address to the DHCP client? Say if the server contains multiple address pool from 192.168.1.x to 192.168.10.x. And the client only can obtain the IP address from pool 192.168.1.x if the relay agent IP is 192.168.1.254. <br>> Thanks in advise.<br>> <br>> Best Regards,<br>> Billy<br>> <br>> _______________________________________<br>> YM -
