Hello,

 

I'm getting extremely poor VPN performance with the ER605 V2.  I'm using Surfshark with OpenVPN.  My network has 6 VLANs and I'm only tunneling one of the VLAN's over the VPN.  When I connect the VPN my download drops from 800 Mbps to 19 Mbps.  That's a 40x drop which is extreme.  I thought it was the VPN provider or the ISP having issues but I've ruled that out by using the exact same configuration on a TPLINK AX11000 gaming router.  With that router I get speeds over VPN of 300 Mbps which is not great (2.5x drop) but I'll take it over 19 Mbps.  This seems like a serious bug in the OpenVPN implementation on what should be a quality Business VPN router.  Maybe the router is underpowered for this arrangement?  The router is controlled from an Omada OC200 SDN appliance.  Any help/suggestions would be greatly appreciated because this is really disappointing. I expected much more from the Omada class of routers and switches.  Thanks.

Yikes. I just stumbled across that spec about 5 minutes ago. Wow, I guess I didn't expect that. Thanks for the reply!
