Hello there!
I have connected two ISPs to RV340.
ISSUE:
VLAN1 DNS settings are set to default.
Is this due to different DNS servers being set to each WAN connection?
Should I have to set same DNS servers for both WAN connections?
I thought of setitng up pi-hole or adguard home on Raspberry Pi and update both WAN connections with Raspberry Pi as DNS server. Befofe I go with that route, I would like to get expers suggestion.
Any further help/advise would be greatly appreciated.
Thank you.

Hi
>>>Enabled network detection on both connection and configuration was successful.
1. Just a point to Note for reference: If you had noticed/recalled, when you were configuring the network-service-detection (under WAN/Multiwan/ page) for WAN1 on which PPPoE-client is configured, you would have noticed that by default when pppoe-wan is configured on a wan interface, the NSD service is set to disable/unchecked....
- this is becos the pppoe-interface has its own built-in health-check of its link using lcp-echo-requests/lcp-echo-replies...and therefore NSD is not required and not enabled for pppoe-wan interfaces...becos it creates issues of link-flapping...
2. So my suggestion is you should immediately disable NSD services on BOTH wan1 and wan2 (eventhough its a static-ip wan) interfaces AND do a apply in both cases AND also do a permanent-save to starrtup-config AND reboot the router once
3. Also later, if you have a linux-host in the lan-network, enable the rsyslogd/syslog-server on it and in the RV34X enable and configure the offload/send logs to syslog-server feature.
- then you may simply check the syslog/logs on the linux-host using the cat/vi commands...or better would be to use the "tail -f /var/log/syslog"
So first do the above, and observe for any further issues...

Thank you so much for your prompt advise. Does disabling NSD impacts load balancing configuration as I have enabled load balancing with 50/50% setting?

>>>Does disabling NSD impacts load balancing configuration as I have enabled load balancing with 50/50% setting?
No. it wont have any impact on Load-Balancing traffic (especially since its a pppoe-wan interface and NSD is anyways supposed to be disabled for pppoe-wan interfaces by default and design)

I made changes and rebooted the router. However, I am still getting intermittent DNS failures.
I tried to access amazon.in from the browser and it throws NXDOMAIN error. I tried to nslookup and ping the domain and it's failed. After few seconds, I was able to do both successfully and able to load the amazon.in in browser as expected.

I have DDNS configured for both WAN1 (Dynamic public IP) and WAN2 (Static Public IP).
VPN is not configured.
Any recommendations?
I see the following in the logs:

ok...
- the error log about ddns on wan1 is about the dyndns-client trying to connect to the dyndns-update-server (by its fqdn), but its unable to resolve the fqdn to the ipaddress becos the ISP1-dns server is not able to resolve it when dns-request is being sent to it from wan1...
can you do the below steps please?
1. edit both wan1 & wan2 AND in both set the
dns1 statically as 8.8.8.8
dns2 statically as 8.8.4.4
- the above are Google's public dns servers
- do this on both wan interfaces
- apply and save
2. Next in the dhcp-server settings on lan interface/vlan1, set the dns to "Use Dns Proxy"
- apply & save
3. Lastly in SystemMnt/System,
- the system name will already be present..either continue or change
- but the domain will be blank by default, so enter either your registered domain-name if you have any, OR give a value such as "test.local" or "myhome.local", dont leave it blank
- apply & do a permanent save too
---------------------------------------
Now ensure a dhcp-renewal on the windows/linux lan-hosts....and then try to browse the net...and check the net connection
Note:The ddns updation is independent & separate from your internet access

Sure.
1. Applied Google DNS servers for both WAN1 and WAN2 profiles.
2. Ensured that DNS Proxy was set for VLAN1 (it's already set to default settings).
3. Domain name is already set to "home.arpa' during setup.
I have attached screenshots of WAN configuration.

Hi
i forgot to mention in addition to above cobfigs to be applied...can you please post a screenshots of your configs in multiwan page?
i want to see the load-balancing settings that you have applied...
10-28-2021 01:14 AM
your configurations (posted by you) are absolutely correct
10-28-2021 04:41 PM
Cool. DNS request time out errors were reduced by around 90% since I made changes that you have recommended. I will monitor for another day and update this thread with result.
Thank you so much for your kind help!!
