Cisco Sandbox ports

[softex123]

Hi,

I am trying to connect on to the Sandbox VPN but connection fails. When I open port access on my network I can get on to the VPN but I am finding it difficult to pin down the port range I need to leave open.

Can you please advise as to the TCP port range required to connect to sandbox VPN.

Thanks

Stephen

Hi Stephen,

TCP port 443 is required for SSL VPN with Anyconnect.

UDP port 443 is required for DTLS over SSL but this is optional.

Hi Stephen,

In addition to jokearns's comment, we're also moving to a model where some ephemeral ports are required. The  range is is anywhere between 20100 and 20354. However, this number will likely grow in the future.

Thanks!
