After switching from ASA 5510 to ASA 5512 strange ack = (big number) behavior?
Posted on 2014-01-22
After switch from ASA 5510 to ASA 5512 the internal network are acting strangely. We can't connect and print to our Konica-Minolta printers. And can't connect to WMware ESX via Sphere. Everything else seems to work OK. Our switch is a Cisco 2960S. No vLan.
The funny thing is when we connect to our hosted office server via RDP we can connect and print.
The ASA's are configured 1 to 1 as closely as possible. Latest firmware on both.
Switching back to ASA 5510 removes the problem.
We have had Cisco people looking at this, but no luck so far, except for the communication to the printer, ACK= are not 1, but a large number?
Does anyone have clue to this?
