Sophos Firewall XG125 with Cisco Switch SG300 10 Ports and Cisco Aironet 1815

Hi Guys

I need help in configuring my Cisco SG300 and 4 Aironet Access point 1815.

I want the firewall to give DHCP to the wireless clients connecting to the AP's

Sophos firewall :

Port 1 have DHCP server for IP 10.0.2.1 connected to LAN network

Port 5 have DHCP server for IP 10.0.30.1 connected to SG300

Cisco SG 300:

Ports 3,4,5,6 are connected to the AP's

port 1 is connected to port 5 Sophos firewall

i have configured DHCP relay in cisco switch and set the DHCP server IP as 10.0.30.1 (firewall DHCP server IP) and now wireless clients get ip from 10.0.30.0 and have access to internet.

Issue1: when i connect another port of the cisco switch to the LAN to be able to access the switch from my laptops it start giving IP from the 10.0.2.1 range to the Wireless clients so how can i stop this while having access to the switch.

Issue 2: only whatsapp calls are blocked, i tried whatsapp calling when directly connected to the modem and its working but when connected to the WLC its stays connecting (no firewall rules blocking), and teams and skype calling are normal.

Thank you
