• Use the no deny udp {source address mask | any | host ipv6-
address} {destination address | any | host ipv6-address}
command
Parameters
source address Enter the IPv6 address of the network or host from which the packets
were sent in the x:x:x:x::x format followed by the prefix length in the /x
format. The range is /0 to /128. The :: notation specifies successive
hexadecimal fields of zero.
mask Enter a network mask in /prefix format (/x).
any Enter the keyword any to specify that all routes are subject to the
filter.
host ipv6-address Enter the keyword host followed by the IPv6 address of the host in

operator (OPTIONAL) Enter one of the following logical operand:
• eq = equal to
• neq = not equal to
• gt = greater than
• lt = less than
• range = inclusive range of ports (you must specify two ports
for the port command parameter).
port port
Enter the application layer port number. Enter two port numbers if
using the range logical operand. The range is 0 to 65535.
destination
address
Enter the IPv6 address of the network or host to which the packets
are sent in the x:x:x:x::x format followed by the prefix length in the /x
