Hi all,

I'm looking for a bit of help getting started with my HP 1820-24g switch .

my network plan :

sophos router eth1(lan 192.168.0.1/24) and i configured the sophos router so : new interface eth4 (192.168.2.1/24) mit VLAN ID :10 function.

i also sophos router configured dhcp scopes for 192.168.2.100- to 200

so i connected sophos eth4 lan cable  -->switch port 1


so i have the native vlan 1, and  vlan 10(port 1-10 tagged) for lan  on the router.

my problem are:
1. if i change sophos interface(eth4)  Vlan funtion to only ethernet and i connect my laptop port 7 then get my laptop IP from sophos router dhcp server.

2.if i change sophos inteface (eth4) only Vlan fuction (vlan 10),then my laptop gets no ip from sophos dhcp server.

any idea and help?
Thank you
