Updates to Sandbox Reservation Internet Access Policy

Due to changes in our networking policies, we are updating the internet access policy within our sandbox reservation instances.
Hosts will no longer have internet access outbound.
This should not affect the overall functionality or access to the resources within the sandbox instances, connecting via VPN.

Keep Innovating!

Issues connecting to devnet VPN

I requested devnet sandbox multiple times but however 99% of times I was not able to connect to VPN.

The only time I was able to connect, the sandbox tore down few minutes after that (about 10 minutes ahead of scheduled time) :-/

 

Currently I'm facing following issues during connecting to VPN:

 


5:40:09 PM Ready to connect.
5:43:18 PM Contacting devnetsandbox-usw1-reservation.cisco.com:20226.
5:43:58 PM User credentials entered.
5:43:59 PM Establishing VPN session...
5:43:59 PM The AnyConnect Downloader is performing update checks...
5:43:59 PM Checking for profile updates...
5:43:59 PM Checking for product updates...
5:44:00 PM Establishing VPN - Initiating connection...
5:44:00 PM Establishing VPN session...
5:44:01 PM Connection attempt has failed.
5:44:01 PM VPN session ended.
5:44:02 PM Ready to connect.

 

Are there any tricks/advices how to be more likely to connect to the VPN?

 

Thanks

Re: Issues connecting to devnet VPN

Is there a solution for this? I still have problems in connecting to VPN. It's working before but now I can't connect using the provided credentials.

Re: Issues connecting to devnet VPN

Similar issue here using the openconnect VPN client. Appears that DTLS handshake is failing.

 

POST https://[vpn-host]:[vpn-port]/
Got CONNECT response: HTTP/1.1 200 OK
CSTP connected. DPD 30, Keepalive 20
Connected as [provided VPN IP address], using SSL
DTLS handshake failed: Resource temporarily unavailable, try again.
[info here about adding hosts/net/gateways mappings]
DTLS handshake failed: Resource temporarily unavailable, try again.
DTLS handshake failed: Resource temporarily unavailable, try again.
[handshake continues to attempt and fail repeatedly]

I removed identifying information in the above console output.

 

Is there something I am missing or is there an issue with sandbox VPN?
