I have different SSIDs for different subnets, one main, one guest, one without VPN. After setting policy based routing so that only the main and guest subnets/SSIDs would go through the VPN, DNS stopped working and I couldn’t ping the gateway (on the main and guest). Disabling DNSMasq did the trick and everything is working now.
I followed the instructions for NordVPN exactly, except the DNSMasq setting. https://nordvpn.com/tutorials/dd-wrt/
Thank you for sharing your solution.

Helped me a lot, because I was initially thinking that I have to fiddle with Iptable rules as well to implement some policy based routing. But works like a charm and so easy. Really love dd-wrt today! 🙂 BIG BIG THX

Hey

Weird. I have my settings I have are
Under DHCP settings
Use DNSMasq for DHCP ON
Use DNSMasq for DNS OFF
Recursive DNS Resolving OFF
Forced DNS Redirection OFF

Also under Local DNS under router IP I just have it empty (0.0.0.0)

And under static DNS 1, 2 and 3 I have the two google DNS servers (8.8.8.8 8.8.4.4) then my isps. Under DNSMasq everything is disabled except for DNSMasq itself. If you’re actually using dnsmasq as a DNS server then you’re on your own cos I could never get it to work properly.

Hope this helps.
Jason

My goal is to allow LAN (172.20.30.1/24) to access other LAN devices and all Internet bound traffic is routed over the VPN.

Router ModelLinksys WRT1900ACS
Firmware Version DD-WRT v3.0-r30796 std (10/25/16)
I’m using Private Internet Access for my VPN provider and the only additional config options they have me set are below
persist-key
persist-tun
tls-client
remote-cert-tls server

I’m thinking it’s something related to DNSMasq settings but am not sure which to change. Any ideas?
Thanks in advance
Jersey
