I am a novice with networks but do have a fair understanding of networks. I have a small business network, utilizing a RVS4000 router (Firmware V2.0.27)
I am attempting to set up firewall rules to block certain web sites at certain times.
I have successfully set up rules using source and destination ranges, to deny service 24 hours a day everyday.
However and here is the problem when I attempt to edit any of the rules (I want to change the time to certain hours of the day) it allows me to edit the rule but when I attempt to save I get an error message up saying there are invalid characters and it will not save the changes?
If I delete the rule and recreate the whole thing with the changes I want it works fine, is this a known bug?
