Hallo Roy,
glad that you are interested in my little Problem
The connection from the Anyconnect clients to the 10.10.110 Network works fine
Also the Tunnel from the 10.10.110.0 Network to 192.168.1.1 Network works fine
The packets from the Anyconnect network get dropped by the firewall before it even reaches the icmp debug output on the asa if I try to ping the remote l2l site

I have a global rule in place to permit all traffic from the Anyconnect VPN named Net_TrustedVPN
even if I put a global permit any any of all traffic the icmp packets get still dropped by the firewall.
further I added the rules for the SitetoSite Tunnel on the ASA
access-list l2l_list extended permit ip object Net_TrustedVPN object Net_DC
nat (outside,outside) source static Net_TrustedVPN Net_TrustedVPN destination static Net_DC Net_DC no-proxy-arp
i cleared the ca but the acl entry doesn't show up?
show crypto ipsec sa
