Hi! I own a Cisco RV345 Dual WAN Router and currently I'm facing kind a strange problem, where i don't know the reasons: I have a fixed external IP from my ISP (assumed 126.96.36.199). Inside my network i have 2 VLANs. Only one WAN is used and active. When i access any website or other IP the outgoing IP is 188.8.131.52 as well. All works fine so far.
Now the problem: When I'm inside my network i cannot access my own external IP via 184.108.40.206. Ping to the network works, but HTTPS doesn't give any response. Actually seems to related to some firewall rules, but currently i don't have any rules defined yet. Even when I deactivate the firewall, no connection possible. When I'm in a different network i can access 220.127.116.11 without problems. Is there anyone of you who had similar problems?
can you include a brief diagram, of your setup, including ip addresses.
also, why do you need to access your public IP on your router, from inside? or is it just a test?
I wouldn't say it is a limitation, but a "security feature". Kind of like with the ASA.
Why this isn't included in the ASA QoSk feature is a question Cisco would need to answer.
But my guess is that Cisco has other devices that do this very nicely and since the ASA is a firewall that only a limited QoS feature was added. Well, that's my 2 cents.
The reason i would need it, is because I use a server with nextcloud, which is accessed through port-forwarding. As i don't want change the config on my devices accessing the nextcloud, I would like to access it through my external IP, even when I'm inside. Of course i can access the local IP inside my network without problems
I currently have 2 distinct VLANs, actually before, when i had just the default one, i could access my own IP without problems. InterVLAN routing is deactivated.
as an alternative you could use a vpn to manage that nextcloud server from external?
Still facing the same problem... I have tried some things...
Strange behavior: When i delete the PORT-forwarding (HTTPS to HTTPS on 192.168.2.10) i cannot access 18.104.22.168 from external (thats what i expected). But surprisingly, when i access now 22.214.171.124 from an internal device, i get the login page of the router... even though i have deactivated remote management.
Its really confusing, do you know what am i doing wrong?
Unfortunately none of the solutions worked.
I found out that the problem is called NAT loopback. So my question now: How can i avoid a NAT Loopback on a Cisco RV 345?
