network-object 172.30.0.0 255.255.252.0
object-group network ssl_vpn_pool
network-object 192.168.75.0 255.255.255.0
nat (inside,outside) source static inside_lan inside_lan destination static ssl_vpn_pool ssl_vpn_pool route-lookup
You must use route-lookup as it cannot determine the egress interface from the NAT.
