Hi Everyone,
ASA inside interface has connection to switch.
ASA inside interface IP 192.168.1.1.
Switch Vlan 1 IP 192.168.1.2
Host PC connected to switch IP 192.168.1.5
questions
From host PC i can ping the internet but not IP 192.168.1.1?
Also from switch i can not ping 192.168.1.1 ?
is above issues is due to ASA design or i am missing comething in my config?
Thanks

Hi,
it should be working by default, can you post your config.

You are denying icmp on the inside:
icmp deny any inside
remove that command and if the issue persists, try configuring the switch port as access for vlan 1.

Hi,
interface Vlan3
description DMZ to 3550DMZ
no forward interface Vlan1
nameif DMZ
security-level 50
ip address 192.168.12.2 255.255.255.0
This is Base Licence restriction:
3 active VLANs (3rd VLAN can initiate traffic to only one other VLAN).
So buy a Security plus licence and everything will be alright provided you configure an ACL to permit traffic from lower level to higher level.
Regards.

Mahesh,
With the configuration of the ASA and the switch port connecting to the ASA we should be able to help.
Also, clear the arp on the firewall, try to ping the switch and check if the ASA has an arp entry for 192.168.1.2
Regards,
Felipe.
