This is on a 2811 running c2800nm-spservicesk9-mz.124-21a.


I have an access list applied as such:

!
interface GigabitEthernet0/0/0
 description QMOE service
 no ip address
 ip flow ingress
 negotiation auto
!
interface GigabitEthernet0/0/0.1
 description PtP VLAN to xxx
 encapsulation dot1Q xxx
 ip address xxx.xxx.xxx.xxx 255.255.255.252
 ip access-group 100 out
 no cdp enable
 service-policy output QMOE-SHAPE

The access-lists seem to not work when configed "out" but works fine
configured "in"

Ping through the interface:

xxxxx#ping 4.2.2.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 4.2.2.2, timeout is 2 seconds:
!!!!!

xxxxx#sho access-lists 100
Extended IP access list 100
    10 deny tcp any any range 135 139
    20 deny udp any any range 135 netbios-ss
    30 deny tcp any any eq 593
    40 deny tcp any any eq 4444
    50 deny udp any any eq tftp
    60 deny tcp any any eq 1433
    70 deny udp any any eq 1434
    80 permit ip any any
xxxx#

The counters do not advance.

I can connect through the interface to a host on port 135, even though the
ACL denies port 135::

xxxxx#telnet xxx.xxx.xxx.xxx 135
Trying 10.14.8.50, 135 ... Open


I looked through the bugs for 12.4/2811 and did not find anything that
matches.

Am I missing something here or is this likely a bug ?

Thanks in advance !
