I have a test environment with 2 hours fireval 5505: The first firewall is remote acces VPN server and the inside side of this firewall is a domain network with a domain controller, DNS server and one workstation. DHCP is off and the PCs have a static address.outside of the VPN server is attached to the outside of the other ASA 5505 firewall. on inner side of the firewall there's one workstation.the workstation would to connect through remote acces vpn on domain network. I have configured remote acces VPN server through a wizard, and his
configuration is as follows
Result of the command: "show running-config"

hi Goran,
Can you ping the DC etc from the ASA? I suppose yes since your LDAP auth appears to work ok.
Do the inside hosts have the ASA as their default gateway, or do they have a route to 192.168.50.0 pointing to the ASA?
If that's not it, I would start by getting captures on the inside interface of the ASA (the one configured for RA VPN) when you ping the DC, to see if your echo requests go out and if there is any reply.

yes i can ping the DC from the ASA. the inside hosts have the ASA as their default gateway.
i work the ping from workstation from the innerside of other asa 5505 firewall (remote access VPN users):
i can ping the inside hosts which connect directly on the ASA, but i can't ping the inside hosts which connect on the ASA over the switch.also, i can't ping the DC because of he is behind the switch.

so you have :
DC ---switch --- ASA1 --- ASA2 --- client
host2 ----------/
and from the client, when it is connected via VPN to ASA1, you can ping host2 but not DC ?
but you *can* ping DC from the ASA?
very strange
the switch is it just layer 2 or is it a L3 switch?
can you do a capture on the inside of ASA1 ?
