This is really not urgent more a little annoying .... so a hint from you will do
My Linksys WRT1900ACS OpenWRT is running 20+ clients on multiple Wireguard interfaces with VPN policy routing in a DMZ on a ASUS AC86U ...... this is stable and highly efficient.
The "opkg update" does only work after several attempts to get connected .... I decided to go from openWrt release to release, so this is not a severe issue I am more interested in finding out why it doesn't work.
The main router ASUS is on a 192.168.1.0/24 net with the router as 192.168.1.1, and it's running clients split on openvpn and directly to WAN.
The Linksys is running a 192.168.2.0/24 net with 192.168.2.1 on the router (gateway and DNS 192.168.1.1) .... DNS: 1 public and 1 wireguard server to each client.
The WAN side is in the ASUS DMZ (DHCP) with the address 192.168.1.236, DNS DHCP feeded from ASUS (1 public & 1 openvpn)
Public and VPN DNS servers are defined by my VPN provider (openvpn and wireguard)
any hints ?
