SF300 as router WAN/LAN isolation

cesar.syscom11
Level 1
Level 1

Hello 

I will appreciate any help on this case, my goal its to setup an sf302-08 as DHCP server for ports 1-8(VLAN2), and also give them internet access. 

What i have done:    Switch on L3 mode, DHCP server enabled

  default VLAN1 (static 192.168.1.1),  pool 192.168.1.1   -  250

VLAN2 (static 192.168.20.1), pool 192.168.20.1 -  250

Ports 1 - 8 (untagged on VLAN2)

so far now if i plug a client hosts to ports 1-8  i'm getting IP addresses from VLAN2 pool (192.168.20.1),

BUT, if i plug my internet modem(WAN) to 1 - 8 , the hosts plugged in sf-302 will get IPs from the modem (ex. 192.168.14.1) and internet access.

My question, how could i "isolate" WAN from LAN, at least dhcp servers, and keep the internet access to hosts.

Thanks!
