Cisco ASA 5505 Voice/Data VLANs not pinging/routing
Hi i am very new to Cisco ASA 5000 series and have two interfaces that i would like to route between, a data network 192.168.69.0/24 and voice 192.168.70.0/24, I have addded both and can ping the respective gateway when on the same subnet, but if i am connect to a data switchport i cannot ping the voice vlan and vice versa.
I thought this was something to do with NAT, so i added nat exempt rules but still no dice. I lack understanding so would appreciate recommendations for books or tutorial sites/videos that will help me understand about ASA policy.
Regards,
Chris

Solution 1:
you need the global command. with the nat (iface) command you specify which traffic is to PAT (NAT but all IPs are translated to one IP) this IP is configured with the global(iface) command for the matching nat ID: Example
nat(inside) 1 0.0.0.0 0.0.0.0
global(voice) 1 interface
any Source IP from the inside Interface will be PATed to the voice Interface IP for traffic that goes from inside to voice. It is also possible to specify an IP address with the global command
your voice vlan interface should have an other security-level, because securiyt level 0 is used for the outside interface and 100 for the inside. with nat and global configured you can access from a higher security-level interface to an lower. if you would like to access from a lower to a higher you need a static
and you will need access-lists for permit/deny traffic for example icmp:
access-list acl-inside permit icmp any any
access-list acl-voice permit icmp any any
access-group acl-inside in int inside
access-group acl-voice in int voice
