ZYWALL 310 SSL VPN: Slow upload speed through secuextender 4.0.3.0

ITDane

I have in long while had a less than stellar experience with the SSL VPN client. 
The issue is that while the download speed from shares and more is okay'ish at about 50 Mbps. The upload speed however is about 10 Mbps. Is there a cap or limit on the client?

BWM is not enabled. I have tried different protocols other than smb, to see if that is the issue, but the same is true for them as well.  I have also tried the IPsec VPN client in the past and that actually performed much better.

Hi @ITDane,

 I tested this symptom but my upload speed is higher than 10Mbps;

Can you share some information with us;

1- What’s your network bandwidth that provided by your ISP?

2- How many client were connected when you test?

3- Can you try to update your SecuExteder software to latest version from the following link and try again?

4- Can you try to create L2TP and see if that’s better for you?

Best regards.
