Needed to Whitelist a Cloud App's Server IP addresses on our office network connected to Cisco RV325 Gigabit Dual WAN VPN Router. This network has been running without incident for over a year and was configured by someone else.
We needed to whitelist these IPs and the FAQ for this unit says [1],
12. [...] Content filtering can blacklist and whitelist access to websites according to keywords and Uniform Resource Locators (URLs).
Sounded like what we need. Followed the instructions for Whitelisting found here, Content Filter Configuration on RV320 and RV325 VPN Router Series [2]
- Firewall > Content Filter
- Accept allowed domans (enabled)
- Added the IPs
Now, after only adding the IPs, various web pages are unreachable and display this message:
"This URLs or Page has been blocked"
There are no blocked sites. Only added the positive rule.
What did adding IP addresses to Accept allowed domans trigger to cause other sites to also be blocked??
EDIT: Fix title; add screenshot
