I bought a RC215w last month - it was one of the few small biz routers that met my requirements and doesn't have an EOS date announced! I read many reviews, split as usual into 'it is great', and 'it is junk'. I assumed that as it was a long-time stable cisco product, and I know that many people have trouble configuring firewalls, the product was probably sound and the negative reviews were down to user error ..... which is how I ended up on this support forum(!)
So now, I'm one of those with users looking to see if there is any input on a problem which I believe has been previously discussed between 2013 and 2016 (see thread: https://supportforums.cisco.com/t5/small-business-routers/rv215w-not-responding-to-outside-connections/td-p/2239112 ).
In summary:
The rv215w is running latest firmware (1.3.0.8) and was configured as a standard router/firewall with all outgoing traffic allowed; and all incoming traffic blocked. It worked as expected.
I changed the admin configuration to allow remote admin via https only from a specific IP. I can access and manage the router from my 2nd location, as expected.
I configured the firewall to enable inbound port forwarding to allow remote access to 4x IP cameras to a specific range of IP's (along with blocks to all other IP's). It works as expected.
So I thought everything was just fine.
However, every few days it seems that the router just stops applying the firewall rules. The router is still still allowing traffic out, but the cameras cannot be accessed from outside, and the admin page is not served. A reboot of the router fixed it and everything is back to normal.
Switching on logging gave a little more information. Informational logging showed that the firewall rules were still being applied and logged properly, but apparently the packets were either not getting through to the target (most likely) or the responses were not being passed back (which I doubt).
So my question is - can anybody shed any 'recent' light on this problem????
Thanks in advance!
