SSL VPN Throughput

MercuryITMercuryIT Newbie ✭
in VPN Client

Hello,

I am looking for some advice on the ideal settings to obtain the maximum throughput with an SSL VPN Client connection.

We have a TZ300 device fully patched I believe.

We are unable to use the Global VPN Client because the users are predominantly MAC users. They are using the Mobile Connect Client. On my Windows PC I am using the NetExtender Client.

When transferring files to a shared file location behind the firewall the throughput just makes it over 1Mbps. I was hoping to see this significantly higher - I have read reports of 8 or 9Mbps are achievable but sure about this.

Can someone run me through any settings I can apply to help increase the throughput.

    Hi @MERCURYIT,

    Thank you for visiting SonicWall Community.

    The SSLVPN or GVC throughput normally depends on the bandwidth at SonicWall installed location and VPN client location respectively. IMO, you should be able to get between 1/3 and 1/2 of the lowest bandwidth on either side.

    I have the same problem...

    we have a 100/100 Mbps bandwidth over fibre, but a connect from mac users at home over SSL VPN is 1 or 2 Mbps. That is lousy.

    Websites behind the firewall (NSA4600 with latest firmware) are very slow and file transfer e.g. over smb too .

    Thanks Saravanan, the main end user is moving house in the next week but I have been testing from my home.

    I will pursue this in the next day.

    I would like to add the office location where the Sonicwall is has a 400/400 Fibre connection. My internet is a 50/20 NBN connection. Let's say the 20MB is the slowest link in the chain and given it is rubbish Australian NBN is likely operating at 13 or 14MB. 1/3 of 13 or 14 is still 4 or 5MB. I'm not seeing anywhere near that.

    Cheers
