The wlc itself is in a different vlan. All communication to other vlans works just fine. I've temporarly disabled the access-lists for vlan Z, without success. A host in the same subnet as the wlc is able to establish communication with a host in vlan Z.</P><P></P><P>How to solve this problem?</P><P></P><P>Kind regards,</P><P>D vd Wege</P> Sat, 03 Jul 2021 21:34:03 GMT https://community.cisco.com/t5/wireless/wlc-can-t-communicate-with-dhcpserver/m-p/772461#M123765 dvandewege 2021-07-03T21:34:03Z Re: wlc can't communicate with dhcpserver https://community.cisco.com/t5/wireless/wlc-can-t-communicate-with-dhcpserver/m-p/772462#M123766 <HTML><HEAD></HEAD><BODY><P>Did you check your routing setting?</P></BODY></HTML> Mon, 03 Sep 2007 19:34:31 GMT https://community.cisco.com/t5/wireless/wlc-can-t-communicate-with-dhcpserver/m-p/772462#M123766 Alejandro Cortes Rivera 2007-09-03T19:34:31Z Re: wlc can't communicate with dhcpserver https://community.cisco.com/t5/wireless/wlc-can-t-communicate-with-dhcpserver/m-p/772463#M123767 <HTML><HEAD></HEAD><BODY><P>Thanks for your reply. </P><P></P><P>In the config of the WLC are no specific routes enabled, except for the default gateway of the management interface.
