ER605 V2 VPN Client-to-Site with OpenVPN Extremely Slow
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.
