OK, got this work.  Had to use a little iptables magic from the linux shell.  I had to imput these two commands: nsoadmin@nso-1D-workshop:~/ncs-run$ sudo iptables -t nat -I PREROUTING -p tcp -d 192.168.88.100/24 --dport 10022 -j DNAT --to-destination 127.0.0.1:10022 nsoadmin@nso-1D-workshop:~/ncs-run$ sudo sysctl -w net.ipv4.conf.ens32.route_localnet=1   I was then able to ssh admin@192.168.88.100 -p 10022 and get right into the netsim.       ...

Hi Jan, As always, you have the answer!  Thanks so much. Here is the finished YANG model:       module load-balancer { namespace "http://com/example/load_balancer"; prefix load-balancer; // Version 5 import ietf-yang-types { prefix yang; } import tailf-ned-f5-bigip { prefix bigip; } import ietf-inet-types { prefix inet; } import tailf-common { prefix tailf; } import tailf-ncs { prefix ncs; } // Service Instance List list load-balancer { key name; uses ncs:service-data; ncs:servicepoint "load-balancer"; leaf name { type string; } list device { description "Defining the target BigIP Load Balancer Information"; key name; leaf name { type leafref { path "/ncs:devices/ncs:device/ncs:name"; } } container ltm { list node { key name; description "list of Internal Web servers nodes"; leaf name { type string; mandatory true; description "Internal Node Name"; } leaf address { type "inet:ipv4-address"; mandatory true; description "IP for the node"; } leaf monitor { type enumeration {enum "icmp";} } } list pool { description "Internal Servers Pools"; key name; leaf name { description "Server Pool Name"; type string; } list members { description "Internal Servers members in the Pool"; key node_name; leaf node_name { description "Use the same node name LAMP_01"; type leafref { path "/ncs:devices/ncs:device/ncs:config/bigip:ltm/bigip:node/bigip:name"; }} leaf port { description "Web Server Port which is 'http'"; type enumeration { enum http; } } leaf address { type leafref { path "/ncs:devices/ncs:device/ncs:config/bigip:ltm/bigip:node/bigip:address"; }} } // terminates list "members" } // terminates list "pool" list virtual-address { key name; description "definiting the Web Server Internal Virtual Address"; leaf name { description "virtual IPV4 address to use"; type inet:ipv4-address; } leaf address { description "Virtual External IP Address xx.xx.10.xx "; type inet:ipv4-address; } } list virtual { description "Virtual IP (VIP) Address Service"; key name; leaf name { description "Name of th External virtual IP Address (VIP) "; type string; } leaf destination { description "Use Virtual Address Name under virtual-address"; type leafref { path "/ncs:devices/ncs:device/ncs:config/bigip:ltm/bigip:node/bigip:address"; }} leaf ip-protocol { description "ip protocol information should be set to 'tcp'"; type enumeration { enum "tcp"; } } leaf pool { description "reference back to the Pool name"; type leafref { path "/ncs:devices/ncs:device/ncs:config/bigip:ltm/bigip:pool/bigip:name"; }} leaf source-address-translation { description "Map the Source address to a specific destination, default automap"; type enumeration { enum "automap"; } } } // terminates the list "virtual" } // terminates the "ltm" record } // terminates the container "device" } // terminates the list "load-balancer" } // terminates the module "load-balancer" ...
