Re: Transparent multiple context... where is the problem...
I suspect the issue is between the ASA Eth0/1.1 and your Switch Fa0/1 trunk. On the switch, usually by default vlan 1 is the native vlan and this vlan is not tagged on the switch side. However, your traffic on the ASA side will be tagged with the dot1q header. Can you try configuring the ip on the main interface of the ASA Eth0/1 instead of Eth0/1.1 and see if this makes a difference ? Or use a different vlan other than 1 between the Eth0/1.1 and the Fa0/1 on the trunk.
