Clear the arp cache?
I've got an ASG220 UTM9 that has a working V7.510 configuration backup restored to it; at least it works on the V7.
The configuration includes additional interface addresses and aliases for company websites that are hosted on internal servers.
When the V7 is in place all internal sites can be pinged and loaded in a browser from the public side, but when the V9 is in place the sites cannot be pinged or loaded.
I have talked with the reseller and Sophos support about this issue, and the next suggestion from Sophos is to clear the arp cache on our ISP's network devices: and Adtran Netvanta 4305 and a FiOS ONT. I would have to power-cycle the devices to do this.
Can anyone confirm this as a viable solution to my problem?
