Hello,
I use access-list to restrict access to telnet.
How to adapt this rule to also restrict telnet access in IPv6?
access-list 50 remark ---Restrict Telnet Access--- access-list 50 permit xx.xx.xx.xx 0.0.3.255 access-list 50 deny any
Do I need to add something like this?
access-list 50 remark ---Restrict Telnet Access IPv6--- access-list 50 permit 2A0A:xxx:xxx:xxxx/? access-list 50 deny any
thanks for your help :-)

Hello,
there is (the same as in IPv4 access lists) and implicit deny at the end. Here is what the ACL for just Telnet would look like:
ipv6 access-list RESTRICT_TELNET_IPv6_ACL
permit tcp 2A0A:DB2:0200::/64 eq telnet any
!
line vty 0 4
ipv6 access-class RESTRICT_TELNET_IPv6_ACL in

the syntax will be bit different, refer below guide has different examples:
