I have an old RT-N66R that would run 5 VPN Clients at the same time with no problems. Today I got a AX86U and pretty much replicated the same settings on it however it will crash every time I try to run the 2nd VPN Client, to the point where it will disconnect my internet entirely and I have to unplug/replug the WAN ethernet cable to get it running again. The last lines of the logs before my internet goes down completely are:
Dec 18 17:20:12 openvpn-routing: Configuring policy rules for client 2
Dec 18 17:20:12 ovpn-client2[6126]: Initialization Sequence Completed
Dec 18 17:20:24 WAN_Connection: ISP's DHCP did not function properly.
