Hey everyone - I just have a quick question/observation that I was wondering if anyone had any input on:
Cisco Adaptive Security Appliance Software Version 9.1(6)
Device Manager Version 7.5(2)
Hardware: ASA5505, 512 MB RAM, CPU Geode 500 MHz,
Internal ATA Compact Flash, 128MB
BIOS Flash M50FW016 @ 0xfff00000, 2048KB
This platform has a Base license.
I have a single VLAN, single subnet home network behind a 5505 that receives a public, outside address via DHCP from as ISP; the ASA is my internal DHCP server. I understand that the ASA does not support address reservations and have tried to use a static ARP as a work-around - as suggested by many posts on the Goggle machine.
dhcp-client client-id interface outside
dhcp address 192.168.1.11-192.168.1.50 inside
dhcp dns 8.8.8.8 8.8.4.4 interface inside
dhcp enable inside
arp inside 192.168.1.2 xxxx.xxxx.xxxx
arp timeout 14400
It seems that even with the static ARP, the DHCP server overrides the layer 3 configuration and my xxxx.xxxx.xxxx machine receives an IP address in the DHCP pool regardless. I’m also perplexed by the fact that I’m trying to reserve an address outside the DHCP pool – the ASA is flat out ignoring the static ARP.
Anyway, this is obviously extremely annoying and I was wondering if anyone else has seen this or has any suggestion. Thanks.
