I’ve been using a PepLink Balance 300 for many years now. Recently, I started blocking IP addresses in the Inbound Firewall section when receiving brute force attacks.
The more rules I added, the slower the Inbound Firewall page became. This is the one that lists all the rules and allows you to delete and modify them.
For a while, I had to request the page 2-3 times (or more) before seeing anything on screen. Now, I constantly get a network timeout. I’ve tried several computers and several browsers, but the result is always the same.
Luckily, I had bookmarked the page to add a rule for direct access. I can still add new inbound rules, with the exception that I cancel my form request after about 5 seconds. The router still recorded my rule, so when I activate changes, everything works fine.
All other parameters are normal and the router is performing as it always as. So, my questions are:
Is there a way I can fix the main Inbound Firewall page to show me the list of rules?
Is there any other way I can manage these rules other than by the web interface? Maybe an SSH connetion not in the docs?
Although I keep a list of blocked IP addresses in a separate document, I sometimes replaces several addresses with a single network mask, but I need to see the list to delete the obsolete rules.
Hopefully, someone has come across this kind of problem before and can help me out.
