Hope someone can help with this common problem.  Have a couple of vlans configured on an ASA 5505 and I can't pass traffic between them.

 

specifically trying to pass traffic between vlan1 and vlan10

 

Thanks for the help.

Can you diagram your setup for us?

 

Thanks

Presumably this is the connection to the 2960x switch?

interface Ethernet0/1

Are your clients able to ping their default gateways on the Vlans?

correct.  ASA 5505 e0/1 connects to 2960x G1/0/44

correct.  vlan 1 client PC can ping 192.168.1.1  and vlan 10 client PC can ping 192.168.10.1

Unlike a Router, an ASA appliance will try and NAT traffic going from one internal subnet to another.

You need to add a static NAT per subnet, as below:

static (inside,PHONE) 192.168.1.0 192.168.1.0 netmask 255.255.255.0
static (PHONE,inside) 192.168.10.0 192.168.10.0 netmask 255.255.255.0
