Hi I have already configure a firewall filter on subnet  "115.189.245.64/28" by defining it as  prefix list "xyz"  in that filter "cc-out" . I want to exclude ip ( 115.189.245.78/28 ) from that prefix list and want that this server should be accessible by only two ips ( 210.250.190.190/32 )  and  ( 210.250.190.211/32 ) . Current filter allow access to that subnet servers to many ips but i want to restrict access of this  ( 115.189.245.78/28 )  for only two ips   ( 210.250.190.190/32 )  and  ( 210.250.190.211/32 ) .

 

Please find below mentioned config of that existing filter and kindly tell me how and where i can that new term for this server  ( 115.189.245.78/28 ) without impacting existing filter : 

 

set groups AA:BB interfaces <*> unit 98 description "aa"
set groups AA:BB interfaces <*> unit 98 family inet mtu 1500
set groups AA:BB interfaces <*> unit 98 family inet filter output cc-out
set groups AA:BB interfaces <*> unit 98 family inet address 115.189.245.65/28
set groups AA:BB policy-options prefix-list xyx 115.189.245.64/28
