I'm having some trouble with a 5610SW IP telephone. The phone is located at a remote site some distance from our IP 500 (5.0.20). The locations are connected via VPN. There are several Avaya 5601 phones at the site working without this problem. Each time the phone boots it comes to a screen...

We have an a network comprised of about 40 ASAs connected via VPN. We have one particular ASA that periodically locks down and loses the ability to establish new connections. This happens during periods of particularly high data transfer (offsite backup) primarily. Now the weird part: once it...

In the interest of full disclosure, I actually studied Access in college. I also got a C and it was my least favorite class during my entire college experience. I earned my C and knew as much about Access the day I finished the class as I did the day I started. Perhaps less. I did learn a...

Some sort of bizarre activity from last night's storm. Came into the office this morning to find out IP500 not answering calls and somehow locked up. The issue with the IPO was resolved by unplugging the electricity and replugging it for a hard reset. However, after this we have continued to...

We have a VPN built by a single ASA 5510 at the center and ASA5505s at the spokes. There are about 40 spokes. Some time ago we began having trouble with traffic back and forth between two of the sites -- it appeared that certain ports were being blocked through the VPN tunnel. After much work...

I have successfully configured hairpinning on two ASA 5505s and an ASA 5510. The 5510 is the central site actually doing the hairpinning. My current frustration is that the hairpinning only appears to work when have interesting traffic coming from both sides of the equation. An example: Hub...

I've been the proud owner of two IP Offices for about two years. I"ve spent a great deal of money buying them and a small fortune trying to make them work. That being said -- they do not function properly 80% of the time. There are two primary problems: 1. We have a series of about 40 Avaya...

I have a network of about 50 ASA 5505s all connected via VPN to a single ASA 5510. When I apply dscp based QOS to an ASA 5505 I use the match tunnel-group xx.xx.xx.xx command to apply QOS to the VPN tunnel back to the ASA 5510. On the 5510 is there a way to uniformly apply QOS to all 50...

I have always assumed (incorrectly I have recently learned) that a VPN provided completely open communication between multiple networks. The issue we're having is that a number of ports that we need open appear to be blocked over our VPN tunnels. This is demonstrated by the following port...

Our VPN is comprised of a ASA 5510 at the hub and ASA 5505s at the spokes. Presently bidirectional communication is possible between all spokes and the hub; however, spoke to spoke communication is impossible. In an attempt to add spoke to spoke communication I added the following commands to...
