I am configuring an ASA 5505 for a small business client to replace Linksys router, and I am having some trouble with it. Any help would be greatly appreciated. Here is my config:

Here is the routing table (nothing plugged in right now other than console):
Gateway of last resort is not set
C 127.0.0.0 255.255.255.0 is directly connected, _internal_loopback
When I have the client connect the asa, no connectivity in or out works. They have two layer 2 switches, no routers.

Hi Wendi,
You need to start making the physical connection in your inside switch and outside interfaces first before atempting to connect to internet or from outside internet to inside.
show route does not indicate any physical connectivity to anything .

Hi, thank you for your reply. I noted in my post that when it IS plugged in, nothing works. I am very aware that connectivity to anywhere will not work without a physical connection. :o)
My concern is mostly my config - I'm looking for any suggestions on what I may have configured incorrectly.
Oh, one other note - shouldn't my static default route be displayed in the routing table whether it is connected or not?
route outside 0.0.0.0 0.0.0.0 xx.xx.215.33 1

Hi Wendy, the default route will show up in routing table once the upstream router is reachable.
I meant also to repost my answer few minutes later thinking that you must have placed back the linksys router becuase connectivity to internet was not happening, my apologies for that, I would have done exactly the same.
When you connect back the firewall connections to inside and outside from firewall itself try pinging your defalt route to confirm you can reach that upstream router. The access from inside to outside by default is permited but you will need some dns configuration for the PC inside to DNS query weblinks.
you could try dhcp address for inside interfaces if you don't have dhcp server and use a public opened DNS servers 208.67.222.222,208.67.220.220
and have this be automatically given to inside hosts dynamically
Example :
dhcpd dns 208.67.222.222 208.67.220.220
dhcpd address 192.168.32.10-192.168.32.100 inside
dhcpd enable inside
for the acl to get access to inside mailserver I would try :
access-list inside_access_in extended permit tcp any interface outside object-group DM_INLINE_TCP_1
access-group inside_access_in in interface outside
but...I would recommend to change the acl name instead of the " inside_access_in " to sort of distinguish what comes from outside to inside within acl names, like outside_access_in gives clear picture for your outside interface acls.
access-list outside_access_in extended permit tcp any interface outside object-group DM_INLINE_TCP_1
access-group outside_access_in in interface outside
remove old one
no access-list inside_access_in extended permit tcp any host mailserver object-group DM_INLINE_TCP_1

so the mailserver is also serving as dhcp server for the inside clients, which is why i turned off DHCP on the router. i have decided that i need to work on this in person - it's difficult to truobleshoot something that isn't plugged in. :) so i'm trying to arrange to make the trek to my client's sit on monday. once I figure out what's wrong I will post it here for future reference. :)

Hi Wendi, just touching base to learn if you have any issues or is all ok?

I haven't been able to coordinate a time to visit the customer until now - I will be going over there tomorrow evening. Will post the results here. :)
