Let's see what chatGPT has to say about our goal

I asked it the following questions

Can you provide a full featured example netscaler config?

Sure! Here's an example configuration of a full-featured NetScaler setup:

> add ns ip 10.0.0.1 255.255.255.0 -type VIP
> add ns ip 10.0.0.2 255.255.255.0 -type SNIP

> add lb vserver lb_http HTTP 10.0.0.10 80
> bind lb vserver lb_http 10.0.0.1 80

> add service svc_web_1 10.0.0.11 HTTP 80
> bind lb vserver lb_http svc_web_1

> add service svc_web_2 10.0.0.12 HTTP 80
> bind lb vserver lb_http svc_web_2

> add servicegroup sg_web_servers HTTP
> bind servicegroup sg_web_servers svc_web_1
> bind servicegroup sg_web_servers svc_web_2

> add lb monitor mon_http HTTP -send "GET / HTTP/1.0\r\n\r\n" -recv "HTTP"
> bind lb vserver lb_http -monitorName mon_http

> add ns vlan vlan_1 10.0.0.0 255.255.255.0
> add ns vlan vlan_2 10.0.0.0 255.255.255.0

> add ns vlan vlan_1 -ifnum 1/1
> add ns vlan vlan_2 -ifnum 1/2

> add route 0.0.0.0 0.0.0.0 10.0.0.2

> add lb vserver lb_https HTTPS 10.0.0.10 443
> bind lb vserver lb_https 10.0.0.1 443

> add ssl certKey cert_web -cert cert.pem -key key.pem
> bind lb vserver lb_https -certkeyname cert_web

> add authentication ldapAction ldap_auth -serverIP 10.0.0.100 -serverPort 389 -ldapBase "dc=mydomain,dc=com" -ldapBindDN "cn=admin,dc=mydomain,dc=com" -ldapBindPassword secret -ldapLoginName samAccountName
> add authentication policy auth_pol_http -rule true -action ldap_auth
> bind lb vserver lb_http -policyName auth_pol_http -priority 100

> add cache contentGroup cache_grp_1
> bind cache global cache_grp_1 -policyName cache_pol_1 -priority 100

> add cache policy cache_pol_1 HTTP.REQ.HEADER("Accept-Encoding").CONTAINS("gzip") CACHE_URL_DEFAULT_EXPIRE

> add netprofile net_prof_1 -bandwidthLimit 200 -burstLimit 300
> bind vlan vlan_1 -netProfileName net_prof_1

> add ssl vserver ssl_vserver_1 -IPAddress 10.0.0.10 -port 443
> bind ssl vserver ssl_vserver_1 -certkeyName cert_web

> add service svc_ldap 10.0.0.100 389
> bind ssl vserver ssl_vserver

Can you explain the different pieces of the config?

Sure, let me explain the different pieces of the configuration:

  1. IP addresses: The first two commands are adding two IP addresses to the NetScaler appliance. The first IP (10.0.0.1) is a Virtual IP (VIP) address and will be used as the front-end IP address for incoming traffic. The second IP (10.0.0.2) is a Subnet IP (SNIP) address and will be used as the back-end IP address for outbound traffic.

  2. Load Balancing Virtual Server: The next set of commands creates a load balancing virtual server (lb_http) for HTTP traffic. The virtual server listens on IP address 10.0.0.10 and port 80. The VIP address (10.0.0.1) is then bound to this virtual server on port 80.

  3. Services: The next two commands add two services, svc_web_1 and svc_web_2, that represent the web servers. Each service has its own IP address (10.0.0.11 and 10.0.0.12) and is listening on port 80. These services are then bound to the load balancing virtual server (lb_http).

  4. Service Group: A service group (sg_web_servers) is then created and both web server services (svc_web_1 and svc_web_2) are added to it.

  5. Load Balancing Monitor: A load balancing monitor (mon_http) is created to monitor the health of the web servers. The monitor uses an HTTP GET request to check the health of the servers.

  6. VLANs: Two virtual LANs (vlan_1 and vlan_2) are created and assigned to specific physical interfaces on the NetScaler appliance.

  7. Routing: A default route is added to the NetScaler appliance to send all outbound traffic to the SNIP address (10.0.0.2).

  8. SSL Virtual Server: A load balancing virtual server (lb_https) is created for HTTPS traffic. The virtual server listens on IP address 10.0.0.10 and port 443. The VIP address (10.0.0.1) is then bound to this virtual server on port 443.

  9. SSL Certificate: An SSL certificate (cert_web) is added to the NetScaler appliance and is bound to the SSL virtual server (lb_https).

  10. Authentication: An LDAP authentication action (ldap_auth) and policy (auth_pol_http) are created to authenticate incoming HTTP traffic. The policy is then bound to the HTTP load balancing virtual server (lb_http).

  11. Cache Policy: A cache content group (cache_grp_1) is created and a cache policy (cache_pol_1) is added to it. The cache policy is bound globally to the cache content group and specifies the content that should be cached based on the "Accept-Encoding" header in the HTTP request.

  12. NetProfile: A network profile (net_prof_1) is created to limit the bandwidth and burst rate of traffic on a specific VLAN (vlan_1).

  13. SSL Virtual Server: An SSL virtual server (ssl_vserver_1) is created to accept HTTPS traffic on IP address 10.0.0.10 and port 443. The SSL certificate (cert_web) is then bound to the SSL virtual server.

  14. LDAP Service

Can you convert this example netscaler config to F5 tmos?

Yes, here is a conversion of the example NetScaler configuration to F5 TMOS (Big-IP) configuration:

# Add IP addresses

  destination 10.0.0.10:443
}

    }
  }
  requires {
    any-of {
      http { }
    }
  }
}

# Bind Authentication Policy to Virtual Server
modify ltm virtual lb_http {
  policies {
    auth_pol_http
  }
}

# Create Cache Policy
create ltm cache cache_grp_1 {
  size 100M
}

create ltm policy cache_pol_1 {
