I just recently lost access to a web page site.   I tried a nslookup and was getting request timed out.  I rebooted the RV340 router and it fixed it.  After the reboot I was able to access the site and nslookup started working.   Why would rebooting the router fix DNS.   I asked and the web site was never down.   Any ideas?  Do you think this is related? ...

Why are you making this so hard.  Just put an IP on the router and probably turn off DHCP.  Then you need a matching IP on the switch.  Your default route on the switch needs to point to the router and the router needs to have routing statements to point to the switch for all the non-connecting networks. ...

@alexten1983 wrote: and how do you have a link set up between router and a switch? As trunk? As I stated above you need to use an Access port and route between the layer 3 switch and the router.  Using a trunk port is just passing data at layer 2.   ... View more

Yes I have 4 VLANs.  One VLAN I call the router VLAN only has the router connecting port with a 30 bit mask. It really does no make sense to run 1 VLAN as you might as well just do layer 2 switching. ... View more

If I use a USB memory stick can I expand my logs. Will it slow down my router?  What speed of USB memory stick?  I don't see it in the manual.   How do I protect against a DNS poison attack?  Are ACLs enough? ... View more

It has happened again tonight.  I faired better maybe because I have tighter controls.  I only seem to have lost DNS as I can ping out on the public network.  I locked IPv6 down with a deny for any.  I have remote access locked to 1 small local network.  I have ACLs which only permit my chosen DNS servers and all other DNS servers are denied.  Will this stop a poison attack?   I am seeing a lot of this in the RV340 logs. 2018-09-06T23:54:56-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:54:41-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:54:26-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:54:11-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:56-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:54-06:00 error license smart_agent: SA-Error: %SMART_LIC-3-EVAL_EXPIRED_WARNING:Evaluation period expired on Aug 15 09:39:46 2018 UTC 2018-09-06T23:53:41-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:26-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:11-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:52:56-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface ...

It happened again tonight.  I seemed to have faired better as I was only down a short while.  I have an IPv6 ACL denying any.  I have remote access locked to one small local network.  Only DNS stopped. I can ping out.  I guess it could be Spectrum again but I don't see anything in the modem log.  I should add I have ACLs to only permit my chosen DNS servers and deny all others.  Will this stop a poison attack?   I am seeing a lot of this in the RV340 logs.   2018-09-06T23:54:56-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:54:41-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:54:26-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:54:11-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:56-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:54-06:00 error license smart_agent: SA-Error: %SMART_LIC-3-EVAL_EXPIRED_WARNING:Evaluation period expired on Aug 15 09:39:46 2018 UTC 2018-09-06T23:53:41-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:26-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:53:11-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface 2018-09-06T23:52:56-06:00 warning network dnsmasq: ignoring nameserver 127.0.0.1 - local interface     ...

Now that I have investigated it further it seems Spectrum switched to Docsis 3.1 last night. I am showing a blue light on my Arris SB8200 modem which I had not seen before.  Maybe they killed my DNS.   Any way I flashed twice with the latest release RV340 firmware so there would not be any traces left of old firmware.  I setup everything again changing the IP network for my layer 3 switch.   I also realized I was not using IPv6 with it unlocked so I created an ACL to deny all access on IPv6. ...

I am not so sure they are looking for network access as much they want me to use rogue DNS servers to load up my workstations and devices.   The  NGFW looks like a little much for my small network. ... View more

I use a RV340 with a Cisco SG-300-28 layer 3 switch.  I use the switch in layer 3 mode.  Default gateway is a layer 2 concept so I use default route instead of default gateway.  So I would point a default route to the RV340 router using an access port. ... View more

Maybe I was lucky but I received my RV340 router put 1.0.01.18 on it.  I then changed the IP network and mask, then turned off DHCP.  I use a Cisco SG300-28 layer 3 switch as the heart of my network.     Is this bug only particular only to the RV345 and not the RV340? Is there any difference between the RV345 and RV340 software wise?  They seem the same to me. ... View more
