Increase Firewall Maximum Table Entries
Navigate to System → Advanced → Firewall & NAT.
In Firewall Advanced:
- Firewall Maximum Table Entries: Set to at least 1000000, unless the system has very little RAM.
NOTE: Without increasing this value, DNS queries take much longer, causing webpages to load very slowly.
As a rough guide, set this value to the following, depending on how much memory there is.
| Memory | Firewall Maximum Table Entries |
|---|---|
| 4GB | 800000 |
| 8GB | 1000000 |
| 16GB | 1200000 |
| 32GB or Higher | 2000000 |
If lots of blocklists are being used, then look at setting these slightly higher if you notice any slowness in DNS resolving.
- Be careful of setting this too high as it directly uses more RAM the higher you set it.
