Hello ,
Hello everyone the router that I am working with is a Cisco c881 (IOS 15.3(3)M5). The problem that i have with it is that when the WAN port, that is configured to
get its setting via DHCP on the ISP side, isn't able to accept the settings it gets sent by the ISP DHCP server. The error that it puts out when "debug dhcp detail" is enabled is:
*May 6 19:22:33.693 eest: DHCP: SRequest attempt # 4 for entry:

My question is if there is some work around this error or if i can stop the router from performing the comparison between renewal and rebind time.
Best wishes
