RSSO dynamic address subtype

The RSSO dynamic address object subtype can be used in a firewall policy's source and destination fields. It allows for more granular and precise policies based on RSSO group membership, enhancing security and flexibility when managing network traffic and enforcing policies.

When the sub-type is rsso, the sso-attribute-value must be set. The IP address of the RADIUS single sign-on user matching the group value will be loaded to the address object.

To configure the RSSO dynamic address subtype:

config firewall address
    edit "test-rsso-addr-1"
        set type dynamic
        set sub-type rsso
        set sso-attribute-value <name(s)>
    next
end

Variable	Description
sub-type rsso	RSSO address sub-type.
sso-attribute-value <name(s)>	RADIUS attributes value.

To check the RADIUS dynamic address database information :

# diagnose test application radiusd {6 | 66}

Test level	Description
6	Show RADIUS dynamic address database summary information.
66	Show RADIUS dynamic address database information.

Example

To configure and use an RSSO dynamic address object:

1. Enable RADIUS account access on port 1.

   When the RADIUS server sends an RSSO message to the FortiGate on port 1, which includes an IP address, the FortiGate will add it to the RSSO dynamic address list.

   config system interface
       edit port1
           append allowaccess radius-acct
       next
   end

2. Configure the RADIUS user and user group for the RSSO address:

   config user radius
       edit "rsso_server"
           set rsso enable
           set rsso-radius-response enable
           set rsso-secret **************
           set rsso-flush-ip-session enable
       next
   end
   config user group
       edit "rsso_g1"
           set group-type rsso
           set sso-attribute-value "rsso_group_1"
       next
   end

3. Configure a dynamic address with RSSO subtype:

   config firewall address
       edit "test-rsso-addr-1"
           set type dynamic
           set sub-type rsso
           set sso-attribute-value "rsso_group_1"
       next
   end

4. Apply the RSSO dynamic address as a destination in the firewall policy:

   config firewall policy
       edit 44
           set name "nat44_policy"
           set srcintf "port2"
           set dstintf "port1"
           set action accept
           set srcaddr "10-1-100-0"
           set dstaddr "test-rsso-addr-1"
           set schedule "always"
           set service "ALL"
           set logtraffic all
           set auto-asic-offload disable
           set nat enable
       next
   end

5. Check the RSSO dynamic address. In this case, 172.16.200.155 is loaded into the RSSO dynamic address:

   # diagnose test application radiusd 6
   dynamic addresses total[vd:root]:0.
   dynamic addresses total[vd:vdom1]:1.
     name, ip_db-total
     test-rsso-addr-1, 1

   # diagnose test application radiusd 66
   dynamic addresses total[vd:root]:0.
   dynamic addresses total[vd:vdom1]:1.
     name:test-rsso-addr-1, ip_db total:1.
           ip,     installed
           172.16.200.155, 1.

   # diagnose firewall dynamic list test-rsso-addr-1
   CMDB name: test-rsso-addr-1
   test-rsso-addr-1: ID(90)
           ADDR(172.16.200.155)
   Total IP dynamic range blocks: 0.
   Total IP dynamic addresses: 1.

6. Send a packet that hits the policy, then check the session to see that the RSSO dynamic address works as a destination in the firewall policy:
