OpenVPN Suddenly not allowing all traffic

Hello I have openvpn and am able to connect to it; however I get no internet connection. Normally, I would just allow all traffic to passthrough and then use the command: iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o enp6s0 -j MASQUERADE It used to work, then suddenly out of nowhere I can longer ...

Re: DNSMasq - Resolve domain name within LAN without loopback support

Hello First, I would like to thank you for helping me - I really appreciate your responses. I understand what you are saying. If on R1 I set the DNS server to 10.0.0.2 then R1 should pass the request over to R2 which is at IP 10.0.0.2, R2 should then forward the port 53 request over to 10.0.1.110. H...

Re: DNSMasq - Resolve domain name within LAN without loopback support

As a side note R2 has nat-pmp enabled and is using 10.0.0.1 as the default gateway (which is LAN1), don’t know if this causes any NAT issues that would cause R2 to filter out the requests.

Re: DNSMasq - Resolve domain name within LAN without loopback support

I set R1 DNS server to 10.0.0.2 but unfortunately R2 must be filtering the requests even though port forwarding is set up and working but some reason the requests only come thru if they come from the real WAN Ip thru R1 then thru R2, it seems strange to me that the request would be filtered out from...

Re: DNSMasq - Resolve domain name within LAN without loopback support

Hi. Basically I have a router r1 (SMARTRG Router) which DHCP ips for lan1 of 10.0.0.0/24 and connected to r1 is another router r2 (Apple Airport Extreme). R2 connects to R1 and has a static ip of 10.0.0.2. Lan2 DHCP ips of 10.0.1.0/24. Both routers NAT. A webserver is configured on lan2 at ip 10.0.1...

Re: BIND DNS

Great advise. I instead got dnsmasq working to resolve my website via LAN in place of NAT loopback support on the router side.

BIND DNS

I have an issue with my router not supporting hairpinning or NAT loopback. Therefore, my domain name refuses connection locally. In fact, 127.0.0.1 or “localhost” from a client fails to work as well. My /etc/hosts file is setup with this info. I was thinking about setting up Bind DNS to overcome thi...

Re: Website - Local issues with FQDN

It’s i've open enable WAN management and now i get the router login page again, I suspect the “connection refused” was due to the router refusing connection to management page, not the server refusing connection.
