Hello
you could possibly utilise MPP (management plane protection) to specify what interface allows what mgt protocol
example:
conf t
control-plane
management-plane
allow xxx interface xxxx

i want to configure acl so how can i configure
i am configuring referance acl as
ip access-list extended ssh_block
permit tcp tunnel_ip of branch WAN_IP_OF_HO eq 22
deny tcp any WAN_IP_HO eq 22
permit ip any any
int eth0/0---> WAN LINk connected on interface
ip access-group ssh_block in

Hello
If its internal to the rtr then apply the acl ingress on the physical interface, However if you want to negate ssh directly to the wan rtr itself then apply it to the vty lines.
Lastly your ACL does look correct
