DELL EMC S4128F-ON Access List deny not working for specific VLAN

I have two core switches and which running VRRP for high availability. (config file attached). In my case I need to create a new VLAN which will be using for guest wifi access. I need to isolate guest wifi from other internal networks. 


I have created VLAN 995 (192.168.40.0/24) for Guest wifi 

VLAN 997 (192.168.31.0/24) is firewall Side and we have two firewalls running active - passive (192.168.31.253 and 192.168.31.254 / virtual Ip is 192.168.31.252)


I have created below access list to allow guest VLAN traffic only to firewall side and need to deny other all traffics 


--more--[2K[0Gip access-list Guest
--more--[2K[0G seq 6 permit ip 192.168.40.0/24 192.168.40.253/32
--more--[2K[0G seq 8 permit ip 192.168.40.0/24 192.168.31.252/32
--more--[2K[0G seq 9 permit ip 192.168.40.0/24 192.168.31.253/32
--more--[2K[0G seq 10 permit ip 192.168.40.0/24 192.168.31.254/32

--more--[2K[0G seq 11 deny ip 192.168.40.0/24 192.168.37.0/24


If I created deny rule to 192.168.37.0/24 still guest users can access the internal network. 


Could you guys check my configuration and let me know what is the error here please ?

Hi,

 

Most likely it should be the routing issue, but we don't have the capability to analyze the configuration of the switch. This would need the technical support to check on it, hence you may need to raise a ticket for it. If you're looking for any of the public to provide feedback, we will wait for someone and monitor the post.
