Cisco ASA 5505 no longer pickup up DHCP lease from ISP
Posted on 2012-08-20
Cisco ASA 5505 running 8.5(5)
This is at a remote site about 9 hours away, so no physical access other than telling someone to do something there. I however have remote access to device via SSH or ASDM due the employee having a Verizon WWAN device there to connect to his laptop with.
Problem: Last week employee called ISP to tell them Internet didn't work; problem has remained since then. Somehow NetINS got a request from them to change the MAC address they use to authenticate for ISP services, and supposedly they did some rewiring at his premise. We went through multiple steps of getting NetINS to use the correct MAC address (eth0/0 on ASA) and we are now back on track there (assigning eth0/0 MAC address directly to W7 PC via registry, and plugging directly into wall where link comes from ISP, now gives us the correct static reservation and routing).
However, the issue is that I cannot get the ASA to pick up a DHCP lease. In fact, I do not even see it giving out requests for one. I currently am mirroring the WAN port on the ASA and capturing with Wireshark, however I have not seen a single request come from the ASA (filtering on bootp protocol). I have disabled, renabled, redid dhcp global configs, etc. reboot reboot yada yada yada... nothing; she seems a bit dead.
Any ideas here? What is my next logical step here?
