Hi,
I recently configured AnyConnect on ASA 5510, 5512 and 5505 with split-tunneling and it's working great. You can refer to the configuration below:
webvpn
enable outside
no anyconnect-essentials
anyconnect image disk0:/anyconnect-win-3.1.14018-k9.pkg 1 regex "Windows NT"
anyconnect image disk0:/anyconnect-macosx-i386-3.1.14018-k9.pkg 2 regex "Intel Mac OS X"
anyconnect enable
tunnel-group-list enable
cache
disable
error-recovery disable
ssl-server-check warn-on-failure
group-alias sslgroup_users enable
group-policy clientgroup internal
group-policy clientgroup attributes
vpn-tunnel-protocol ssl-client
split-tunnel-policy tunnelspecified
split-tunnel-network-list value SPLIt-ACL
tunnel-group sslgroup type remote-access
tunnel-group sslgroup general-attributes
address-pool vpnpool
default-group-policy clientgroup
tunnel-group sslgroup webvpn-attributes
nat (inside,outside) source static 10.100.20.0-24 10.100.20.0-24 destination static 10.100.21.0-24 10.100.21.0-24
access-list SPLIt-ACL standard permit 10.100.20.0 255.255.255.0
access-list SPLIt-ACL standard permit 10.100.21.0 255.255.255.0
Question: I have multiple L2L VPNs configured on these ASAs. What I want to do is to access the resorces of those of L2L tunnels via Anyconnect. Is this do-able?
Thank you,
Abhi

Hello,
Is the VPNPool part of the network assigned to the Inside Interface ?
Are the destination networks on the L2L's part of the tunnel Exclude ACL ?
If the tunneling and routing in place it should work but seeing only the partial configuration and not knowing more about the topology - I cant say for sure yet.
Best regards,
Paul

To add to Paul's response, "same-security-traffic permit intra-interface" also needs to be added to allow Anyconnect traffic to u-turn on the outside interface into the L2L tunnel.

It's allowed\, please check running-config and let me know if any issues.

No, it's a totally different subnet as you generally create in Anyconnect VPN pools
I haven't created any rule as such
If the tunneling and routing in place it should work but seeing only the partial configuration and not knowing more about the topology - I cant say for sure yet.
Please check the running config, hope it helps.

There’s not enough configuration here to provide you a detailed response to meet the behavior you are looking for.

The L2L tunnel configuration is missing as well as the ip local pool configuration. It's hard to follow the flow without more information.

For troubleshooting routing and NAT issues, I would suggest Packet-Tracer Demo on Cisco ASA - YouTube
