Not able to Ping

L1 Bithead



I have l3 switch , new vlan is created and its default gateway is PA FW..A machine when connected to trust interface eth1/2 is able to access the internet...but when machines are connected to switch with trust IP range,internet is not working.

My machines are not able to access internet,but when i connect a single machine to FW Trust Lan interface internet is working.


Default route is given on FW is and next hop is ISP Ip(182.71.x.x)..kindly tell me what need to done for machine to get internet.

i would guess your switch port is set to trunk mode or is otherwise tagging it's packets with a VLAN tag which the firewall will ignore if you did not create a tagged subinterface


the solution is to create a tagged sub interface on the firewall that matches the .1q tag and hsas the IP and zone configuration

Firewall and switch interface vlan are in the same net? If not, try putting a static route on firewall
Destination -> Desktop network -> next-hop interface vlan of the switch.
