ASA 5505 DHCP issue

moritz.orphall — Tue, 05 Jan 2021 20:28:36 GMT

Hello,

I resetted the old ASA 5505 back to the factory results, but DHCP is still not working. Clients on port 1-7 dont get an IP address, I also renewed the network interface driver. The Gateway interface is on port 0. Do you have any suggestions to me?

Thanks

Moritz Orphall

Do you intend on the ASA being the DHCP server or will DHCP be hosted by another device?

I confused the error show SIP and you ask about the DHCP and there is no mention where is the DHCP config.

If the ASA you looking to be DHCP Server, you need to configure the device act as DHCP, by nature it can not be DHCP Server, this is more of FW.

Once wipe all the config gone, you need to build one as per the requirement.

here is DHCP Server config, if you interested to configure :
