Anyconnect and Airplay/AirTunes

At home I often stream music from my Macintosh laptop (OS 10.7.1) to my sound sytem usinf AirPlay/AirTunes. On my local LAN, the AirPlay device is located at 10.0.1.3 . Baseline Netwoork State established

I then connect to my university network using AnyConnect client (3.0.3054). University policy disallows local LAN access during VPN connectoins, so AirPlay device disconnects and is not reachable. Device dissappears from iTunes "Select Speakers" menu. OK, I accept that. Network stae has changed

I then disconnect VN and terminate AnyConnect client application. Airplay devices reapear in

iTunes "Select Speakers" menu. But clicking on the connect box has no effect. AirPlay device 10.0.1.3 is mising from routing tables. Network state has not returned to Baseline. Only way to recover appears to be system reboot.

What's gone wrong?

Anyconnect and Airplay/AirTunes

Hi Wesley,

can you please clarify "10.0.1.3 is mising from routing tables" ?

What does your routing table ("netstat -rn") look like before and after the vpn connection?

Can you ping 10.0.1.3?

Is it in your arp table ("arp -a")?

Re: Anyconnect and Airplay/AirTunes

On my LAN, 10.0.1.3 is the address of my Apple Airport Express, an AirPlay receiver device.

After fresh reboot of MacBook Pro, Netstat displays:

iTunes cannot reestablish connection to AirPort. It appears in menu, but clicking on checkbox doesn't check the box

Re: Anyconnect and Airplay/AirTunes

Hi Wesley,

well, if you can ping it, I suspect that if you do an "arp -a" (or a netstat) after the ping, it will show up in the ARP table, so not sure why iTunes cannot reach it.

Actually I'm not sure how iTunes connects to the Airplay,  maybe you can run Wireshark (or any other sniffer) to see what happens exactly on the network

A) in a working situation, i.e. when you enable that checkbox before running anyconnect and

B) in the failing situation.

Re: Anyconnect and Airplay/AirTunes

Hello Wesley,

I had the same problem and I was able to solve it by disabling IPv6 on my Mac.

System Preference -> Network -> Ethernet or Airport -> Advanced -> Configure IPv6: OFF

I hope this work for you!

Re: Anyconnect and Airplay/AirTunes

Using OS X Lion. Choices for IP6 are

  • automatic
  • manual
  • link-local only

OFF not an option. Tried link-local only, no help

Re: Anyconnect and Airplay/AirTunes

Hello,

I have Snow Leopard and I have the "off" option...

If you google "turn off ipv6 in lion" I can see a few option to turn it off.

To determine that the problem was the IPv6, I've used Wireshark (http://www.wireshark.org/download.htm) and then you clearly see that the communication between the computer and the airportExpress switch to ipv6 after using using the cisco VPN.

I hope this help

Jonathan
