Extended access list on Cisco routers

Can you edit an access list without delete the entire list? In other words, can you remove a sequence entry with the access list?
Thanks

Yes, you can. If you do sh access-list, the router will show the sequence number. You can than add a sequence, delete a sequence or change one.
For example if you have an acces-list like this:
Extended IP access list test
10 deny ip 10.10.10.0 0.0.0.255 any log
15 deny ip 11.11.11.0 0.0.0.255 any log
you can now add a new sequence between 10 and 15
11 deny ip 172.16.10.0 0.0.0.255 any log
You just have to make sure to use the sequence number when you create the last access-list

LMS 4.2 Compliance check extended access-list

Hi,
I would like to check of our router has one specific line in an extended access-list. I have tried to use the 'baseline compliance' to get the output, but can't get the syntax right.
I would like to avoid checking on the line number in the access-list, because this is not the same on all the routers.
I have made a new compliance check like this:
'submode': ip access-list extended 'acl-name'
+deny tcp any any eq smtp
But that is not working, Can some one show me the 'right path'?
Thanks

Extended access list with multiple ports

Hello All,
I have a problem with my Cisco Catalyst 4503-E when i try to configure an extended access lists with multipleports.
I receive the following message:
The informations of my Switch are the following:
Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500-IPBASE-M), Version

Best regards.

Thank you Alex for your response.
Yes, this is an example:

I have more ACLs and each ACL contains more conditions with multiples Por

ICMP Inspection and Extended Access-List

I need a little help clarifying the need for an Extended Access-list when ICMP Inspect is enabled on an ASA. From reading various documents such as the following (http://www.cisco.com/c/en/us/support/docs/security/pix-500-series-security-appliances/15246-31.html), I CAN allow ICMP through my ASA using an extended access-list or enabling ICMP Inspection in the Modular Policy Framework. Is that true? I only NEED an Extended Access-list or enable ICMP Inspection? I do not need both? Or is it best practice to do both?
What does the ASA do to a PING from a host on the inside interface (Security 100) to host on the outside interface (Security 0) when ICMP Inspection is enabled with the following commands:
policy-map global_policy
class inspection_default
inspect_icmp
However, the following commands are NOT placed on the inbound Extended Access-list of the outside interface:
access-list inbound permit icmp any any echo-reply
access-list inbound permit icmp any any source-quench
access-list inbound permit icmp any any unreachable
access-list inbound permit icmp any any time-exceeded
access-group inbound in interface outside
Will the PING complete?
Thank you,
T.J.

Hi, T.J.
If problem is still actual, I can answer you this question.
Let's see situation without ICMP inspection enabled:
The Cisco ASA will allow ICMP packets only in case if ACL entry exist on interface, where packet goes in. If we're speaking about ping, then ACL rules must allow packets in both directions.
In case with ICMP inspection, with ACL entry you should allow only request packets, replies will be allowed based on ICMP inspection created connection.
Speaking about your particular example with different security levels - with default ACL rule, that allow traffic from higher interface to lower - NO, you can do not enter that rules you described, and as you'll have successful ping.
If you deleted this rule and administrate allowed traffic manually, then YES, you must allow ICMP requests to have successful ping.
P.S. It's not a good practice to leave that default rule, which allow traffic from higher sec.lvl. to lower.

Change an extend access list in a prefix list

Hallo All,
I would like to translate an extend access list in a prefix list.
ip access-list extended x_to_y
permit ip 1.1.1.1 0.0.1.255 any
deny ip any host 3.3.3.3
Any hint?
Thanks!!!

Hi Fabio,
I am sorry but to my best knowledge, this is not going to work.
You want to perform Policy Based Routing (PBR). For PBR, the packet selection is based on inspecting their header values by an ACL. A prefix-list does not inspect header values; rather, it would inspect routing update contents. This is also the reason why you cannot figure out how to rewrite the second line - because a prefix-list does not have a source-and-destination semantics. It is simply a list of network addresses you would be looking for in routing protocol updates.
Even the documentation at
http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_pi/configuration/15-mt/iri-15-mt-book/iri-pbr.html
clearly shows that the only supported match commands are match length and match ip address - not match ip address prefix-list.
I wonder - how come that your platform is unable to accomodate an ACL for PBR in hardware? Can we perhaps try to make this work? A prefix-list is not the way to go.
Best regards,
Peter

Configuring Extended Access List with Any statement

I have several questions where I'm fuzzy on a configuration already on my network. Whoever setup my network before me just put the same access-lists on all the interfaces at three different locations --
1. Are extended access-lists always source then destination? Like in the following statement:
permit ip host 172.16.4.20 any - Is the source 172.16.4.20 and destination any?
2. Further down though there is:
permit tcp any host 172.16.4.11 eq 443.
In that case is the source any host and the destination 172.16.4.11 ?
This had been placed on an inbound access-list but 4.11 is not internal to that network so I don't think that statement if valid.
3. Also, when you do a:
sho ip access-list -
Not many of the line items in that access have any counts - does that mean nothing is hitting them or like I think they could be misconfigured?
Thanks!

Thank you Alex for your response.
Yes, this is an example:
permit tcp 192.168.1.0 0.0.0.255 host 192.168.2.1 eq 135 389 636 445 3268 3269 domain 88

ASA 5505 version 9.1 in extended access-list I can add interface name as destination??

Hi All,
I'm adding extended ACL on the ASA 5505 version 9.1 and found that in the source or destination field I can specify interface name instead of object, host/network but can't find it documented anywhere and what is the behavior of that?
access-list VOICE_IN extended permit ip object obj-VOICE-LAN interface OUTSIDE
Is it matching the egress interface or what?

Use the interface name rather than IP address to match traffic based
on which interface is the source or destination of the traffic. You must
specify the interface keyword instead of specifying the actual IP
address in the ACL when the traffic source is a device interface. For
example, you can use this option to block certain remote IP addresses
from initiating a VPN session to the ASA by blocking ISAKMP. Any
traffic originated from or destined to the ASA, itself, requires that you
use the access-group command with the control-plane keyword.

Access-list in Cisco 3560 Series Switch

Guys,
I will be implementing access-lists in 3560 switch. Hope you can help me with the configuration. I'm planning to block all ports by default and only allow ports that the user need to access. The ports will be as follows, tcp - 80, 81, 8080, 25, 110, 143. For udp - 23 and port used by IP Phone.
Hope you can help me guys.
Thanks,
John

and then dont forget to call this access-list on the interface or vlan you want to apply it.
You can use a number for the ACL > 100 or a name as indicated earlier.
If you go with just a number :
access-list 100 permit tcp any any eq 80 81 ...
access-list 100 permit udp any any eq 23
int g1/0/1
ip access-group NAME in
OR
ip access-group 100 in
As for example :
NMS-3750-A(config-if)#ip acc
NMS-3750-A(config-if)#ip access-group ?
<1-199> IP access list (standard or extended)
<1300-2699> IP expanded access list (standard or extended)
WORD Access-list name

Extended access-list error using FQDN

Hi,
I'm trying to add an access-list rule to allow internal servers to connect an outside host on a asa 5540. The hostname translates to multiple ip's. Normally I just lookup the ip address or one of the ip's the hostname translates too and use that in the access-list as the host.
For some reason the actual ip's, which are a few, are not always available so using a specific ip sometimes does not work, thus the reason I have to use the hostname instead of the ip. I have 2 hostnames. www.hostname.com and subdomain.hostname.com.
This is how I normally add these rules (the ip addresses are fictive):
access-list internet_access extended permit tcp host 192.168.50.5 host 84.115.57.121 eq www log
When I try to add this using the hostname on our asa I get an error:
access-list internet_access extended permit tcp host 192.168.50.5 host www.hostname.com ?
ERROR: % Unrecognized command
I've tried it without the 'www', so hostname.com but same error.
How can I solve this?
Thanks in advance for your time and help
Regards,

@zulqurnain
Thanks for your reply. Indeed the asa does not allow me to use a hostname. The question is, how can I still make this work without going for 'any' or adding all the possible ip's it might translate too.

Extended access list question

Hello,

access-list 100 permit tcp any host 192.168.155.18 established
access-list 100 deny udp any host 192.168.155.18

The server 192.168.155.18 should only answer on requests on port 53 (tcp and udp). IOS image is c7200-jk9s-mz.124-25c.bin. Applied this access-list I can still connect through any other port like ssh and so on.

ACL - extended access lists

Hi, I'm working through the CCNA ICND2. Section: IP Access Control Lists
On p246 it says "the access-list command must use protocol keywork tcp to be able to match TCP ports and the udp keyword to be able to match UPD ports"
in an example on p264 they list the statement "access-list 101 permit any any eq telnet"
I would assume that "telnet" is a word value for "port 23" (just like you can type "eq www" instead of "port 80")
therefore does it not have to read "access-list 101 permit tcp any any eq telnet"
??? many thanks for your answers - much appreciated.

it's a typo!!

Port Forwarding & Access List Problems

Good morning all,
I am trying to set up port forwarding for a Webserver we have hosted here on ip: 192.168.0.250 - I have set up access lists, and port forwarding configurations and I can not seem to access the server from outside the network. . I've included my config file below, any help would be greatly appreciated! I've researched a lot lately but I'm still learning. Side note: I've replaced the external ip address with 1.1.1.1.
I've added the bold lines in the config file below in hopes to forward port 80 to 192.168.0.250 to no avail. You may notice I dont have access-list 102 that i created on any interfaces. This is because whenever I add it to FastEthernet0/0, our internal network loses connection to the internet.

Hello,
According to the config you posted 2.2.2.2 is your wan ip address and 1.1.1.1 is the next hop address for your wan connection. The ip nat configuration for port forwarding should look like
Ip nat inside source static tcp 192.168.0.250 80 2.2.2.2 80
If your provider assigns you a dynamic ipv4 address to the wan interface you can use
Ip nat inside source static tcp 192.168.0.250 80 interface fastethernet0/0 80
Verify the settings with show ip nat translation.
Your access list 102 permits only tcp traffic. If you apply the acl to an interface dns won't work anymore (and all other udp traffic). You might want to use a statefull firewall solution like cbac or zbf combined with an inbound acl on the wan interface.
Best Regards
Lukasz

Convert named access list to line numbers

I printed out a document months ago which has since then disappeared into my mountains of paperwork. Somewhere in that document listed a command that converted an extended, named access list to one with line numbers. I even recall that you could input the line interval into the conversion process (so lines would be 5,10,15 etc or 10,20,30 etc).
I just upgraded a 6509, and I'm ready to put line numbers in my access list, and can't find the command - a new Cisco search is coming up empty. Can anyone recall what the command is?? Again, it's for converting an existing access-list with no line numbers to one with line numbers.
Thank you!

Hi Emily,
I guess this is what you are looking for. I have not tried it my self but would like to test it out.
1. enable
2. configure terminal
3. ip access-list resequence access-list-name starting-sequence-number increment
4. ip access-list {standard | extended} access-list-name
5. sequence-number permit source source-wildcard
or
sequence-number permit protocol source source-wildcard destination destination-wildcard [precedence precedence] [tos tos] [log] [time-range time-range-name] [fragments]
6. sequence-number deny source source-wildcard
or
sequence-number deny protocol source source-wildcard destination destination-wildcard [precedence precedence] [tos tos] [log] [time-range time-range-name] [fragments]
7. Repeat Step 5 and/or Step 6 as necessary, adding statements by sequence number where you planned. Use the no sequence-number command to delete an entry.
8. end
9. show ip access-lists access-list-name
