Slow to no Upload speed via VPN

Hi,

I have the following setup (in short):

  • Router: RB4011iGS+
  • VLAN enabled Managed Switch from Netgear
  • WiFI AP from LinkSys

Internal network logical view:

  • Wifi has an SSID which encapsulates all traffic with VLANID 50
  • The Switch lets the VLANID traffic pass from Access Point to Mikrotik
  • On the router I have a VLAN interface defiened for the VLANID 50 with a dedicated local IP

External network:

  • I have a VPN connection via (L2TP without IPSec or a PPTP without IPSec or an IPSec tunnel) - Same provider multiple configuration options (not all 3 in parallel)
  • In the router I have all the traffic that comes from the VLAN based network to be masquerade and pushed through the VPN
    – Either as Mark-route firewall for L2TP and PPTP
    – Or as IPSec route network for IPSec Tunnel

Issue:

  • If I connect to the SSID that routes the traffic via the construct above, I have good ping < 25 ms, good download > 100 Mbps but almost no Upload < 0.01Mbps (0,01% of my bandwith)
  • If I use the VPN from a mobile device or Workstations I have the expected upload speed
  • If I don’t use the SSID VLAN based I have the expected upload speed

Any hints where I could dig dipper ?

Thank you in advance for any thoughts :slight_smile:
