Hi everyone, I am unsuccessfully trying to implement Web Filter Category quota on my 40F. 2 problems: despite time limit set under a monitored category, (1) client device has access to websites falling within that category beyond such time limit. And (2) in the Fortiguard Quota Monitor dashboard, FortiGate displays “No matching entries found” for this client IP. Current setup:License activated;Explicit Proxy features activated;Fortiguard filtering services on port: 8888; no report received after launching connectivity test;Network > Interface: Explicit Proxy (HTTP 8080, no PAC file) on that Vlan (10 clients, 5 laptops, 5 mobiles);Policy & Objects > Firewall Policy in proxy-based for this Vlan to ISP;Policy & Objects > Proxy Policy proxy-based with Web Filtering profile on that Vlan address range;Security Profiles > Web Filter profile on proxy-mode; andClient proxy manually set up with Vlan IP Interface and Explicit Proxy port.What I can see:Client accessed page is apparently buffered (no immediate streaming);traffic appears in Proxy Policy;the FG displays “no matching entries found” in the Fortiguard Quota Monitor;the FG cannot ping the client device anymore (ie it pinged it before implementing this proxy policy) but still pings FQDN or external; andif Firewall Policy in proxy mode is disabled, then client mobiles connect without being granted internet access. Having been through the Troubleshooting Tip: FortiGuard Web Filtering problems, I am stuck in test 5. For recap and confirmation:test #1: service enabled, but not sure to understand the meaning of the flags;test #2: success;test #3: success;test #4: success. I also tried to change the listened Explicit Proxy HTTP port to 8888, as well as in the Client settings. The FortiGate just recorded one second of access to the categorized website. Am not an IT guy and am clearly doing something wrong. Hope you’ll give me some corrections/tips to move on. Thanks !

FortiOS 7.2.x - Web Filtering quota issues - no matching entries found

Hi everyone,

I am unsuccessfully trying to implement Web Filter Category quota on my 40F.

2 problems: despite time limit set under a monitored category, (1) client device has access to websites falling within that category beyond such time limit. And (2) in the Fortiguard Quota Monitor dashboard, FortiGate displays “No matching entries found” for this client IP.

Current setup:

License activated;
Explicit Proxy features activated;
Fortiguard filtering services on port: 8888; no report received after launching connectivity test;
Network > Interface: Explicit Proxy (HTTP 8080, no PAC file) on that Vlan (10 clients, 5 laptops, 5 mobiles);
Policy & Objects > Firewall Policy in proxy-based for this Vlan to ISP;
Policy & Objects > Proxy Policy proxy-based with Web Filtering profile on that Vlan address range;
Security Profiles > Web Filter profile on proxy-mode; and
Client proxy manually set up with Vlan IP Interface and Explicit Proxy port.

What I can see:

Client accessed page is apparently buffered (no immediate streaming);
traffic appears in Proxy Policy;
the FG displays “no matching entries found” in the Fortiguard Quota Monitor;
the FG cannot ping the client device anymore (ie it pinged it before implementing this proxy policy) but still pings FQDN or external; and
if Firewall Policy in proxy mode is disabled, then client mobiles connect without being granted internet access.

Having been through the Troubleshooting Tip: FortiGuard Web Filtering problems, I am stuck in test 5. For recap and confirmation:

test #1: service enabled, but not sure to understand the meaning of the flags;

test #2: success;

test #3: success;

test #4: success.

I also tried to change the listened Explicit Proxy HTTP port to 8888, as well as in the Client settings. The FortiGate just recorded one second of access to the categorized website.

Am not an IT guy and am clearly doing something wrong. Hope you’ll give me some corrections/tips to move on.

Thanks !

Hi Sylvain,

If you are encountering the "No matching entries found" message when trying to add or view web filtering quotas in FortiOS 7.2.x, it indicates that no custom quotas or categories have been added yet:

Access Security Profiles: Navigate to the "Security Profiles" section in the FortiGate GUI.
Select Web Filter: Click on "Web Filter" to access the web filtering settings.
Edit Web Filter Profile: Choose the web filter profile you wish to edit or create a new one.
Add Category Usage Quota: In the "Category Usage Quota" section, click on "+ Create New" to add a new quota and define the category and set the desired quota limits.
Save Changes: After configuring the necessary settings, ensure you save the changes to apply the new quotas.

Best Regards

Hi Anthony, many thanks for the follow up. Web Filter was set up adequately and selected in the Proxy Policy.

Hi,

I think the issue is in the fact that you are using Explict Proxy , instead of granting access directly to the devices w/o using a proxy.

In the documentation, https://docs.fortinet.com/document/fortigate/7.2.11/administration-guide/801136 , it states that a firewall policy should be in proxy mode and also the web filter and the category in question in Monitor.

Due to the fact that you are using a proxy address on the stations and a proxy policy with defines that traffic is allowed and not using a firewall policy because of that, most likely this would be the reason.

Hi, thank you for this.

Having checked with Support, I am now testing a Firewall Policy in proxy mode together with Explicit Proxy (no PAC file yet) and Category quota working on. Support added a deny firewall policy for quic. Confirmed in Firewall User Monitor showing 1 authenticated client in "Firewall", none in "Proxy". Forti Policies dashboard shows relevant firewall type policies.

But, I thought that I needed to set up a purely Proxy Policy to work this out. So if I disable that Firewall Policy in proxy mode and enable the corresponding Proxy Policy (same Web Filter and Category Quotas - except that SSL is set at handshake inspection only), why does this not work ?

The testing device gets internet access without prompting the interface authentication page anymore.

Forti Policies dashboard displays no Proxy type policy and the Implicit Deny Firewall type from root. No Proxy user in dashboard. Quota Dashboard shows the IP of testing device without timing data.

I am definitely missing something, as I can't seem to get the difference between a Firewall policy in proxy mode and a "true" Proxy policy. Googled that without success yet.

hi,

you could have a read here, https://docs.fortinet.com/document/fortigate/6.4.0/parallel-path-processing-life-of-a-packet/466137/introduction

so basically you have 2 options to grant users access.

1. with a explicit proxy - where the user sets a proxy ip:port in system settings ( +auth optionally ) and then it is granted access, no firewall policy needed, just a proxy policy with UTM profiles ( AV/Web Filter/DNS/etc )

2. with a firewall policy ( either in flow-mode or proxy-mode ) - where the user doesnt have to do anything in system settings , where you need a firewall policy to grant access based on source IP and dst IP/ISDB, also UTM profiles

with the 2nd option there are several options to auth users out there, AD polling/SSO/etc
