Show ip access-lists with remarks?

We have a 6509E and use ACLs for our SVIs. When viewing specific ones created I use "show ip access-lists NAME" and when finding remarks I have to constantly go back to the "show run | b NAME" but its seems clunky. Is there way to see the view of the first with the sequence numbers but show the remarks that I can only find in the show run?

Ok , i understand that i will have to use the public IP in my ACL on the ADSL connected interace.
If i obtain a private IP on my ADSL interface from the ISP, then is it the best method to aply the ACL on the LAN interface and assign it as IP ACCESS-GROUP xxx OUT ????
And one more question.
I understand the concept with ACL with one public IP that will be NAT (overloaded). What if i am using multiple public IPs that i will NAT on all of them ???
how does this affect my ACLs. Is there a way around this ????
Thanks,
George

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:

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

APEX Pages - User Access List with NTLM

Hi,
I'm building several APEX Applications, and using NTLM as its Authentication Scheme. With this, the users won't have to type any user and password. And their user name stated in top right screen.
I'd like to build another application to administer users of all created APEX Applications. So I'd like to build 3 tables:
1. users (hold user name, and user data)
2. pages (hold APEX Applications pages)
3. access_list (hold combined data of users and pages and access flag)
The last table will give me an SQL that can be used to create page level Authorization Scheme.
The problem is:
I cannot find a way to get a list of user ids to pre-populated the table users. Is there a way that an administrator user use an LOV of all NTLM user instead of typing domain\user to this application? OR is there a better and elegant way to create User Access List with NTLM.
Your helps will really help me, and thanks in advance.
Regards,
Aulia

This is kind of a followup to Scott's post. Instead of using your own tables to map user accounts to permissions etc, why not simply use LDAP to query the NT domain global catalog?
You can tell what users are members of particular AD groups and control access to functions based on AD group membership. Then you would only need one table that maps Apex functionality to AD groups.
That's what we do. Our account management people add users to different security groups and they get access to our apex app based on those groups. The type of access is controlled by the group to which they belong.
If you try to capture a list of all users, you'll be constantly trying to keep your list of users in sync with your AD/NTLM accounts.
Or I guess you could simply use LDAP queries inside the database to get a list of ALL your users in a nightly batch. Wouldn't help for people added in the middle of the day, but maybe that doesn't happen often in your company.
I have posted code on using Active Directory LDAP with dbms_ldap inside the database. Shouldn't be too much trouble to modify that code to scan your directory for users every night. Search for "dbms_ldap" in this forum.

Nexus1000v : ip access-list with port range

Hi,
I am configuring ip access-list policy with port range on Nexus1000v. I want to block traffic of a VM based on specific port or port range. Following is the example showing, blocking of rdp service (port - 3389) of vm x.x.x.x. But the scipt blocks all traffic of x.x.x.x.
Can any body verify the scirpt and tell whats the problem with the script?
vm x.x.x.x is on Veth2
config t
ip access-list Veth2_rc_vmfw_acl_in
deny tcp any host x.x.x.x eq 3389
exit
ip access-list Veth2_rc_vmfw_acl_out
deny tcp host x.x.x.x any eq 3389
exit
interface Veth2
ip port access-group Veth2_rc_vmfw_acl_in in
ip port access-group Veth2_rc_vmfw_acl_out out
exit
exit

Access list with multiple object groups

Hello Everyone,
I am using a cisco ASA 5525 with 8.6 code. I am trying to setup access list for oubound access meaning hosts accessing the internet. I have created an access list called outbound_access and did "access-groupc outbound_access in interface inside "
I am trying to use object-groups where ever i can. Here is an example.
object-group service obj_Meraki_outbound
service-object tcp destination eq 443
service-object tcp destination eq 80
service-object tcp destination eq 7734
service-object tcp destination eq 7752
service-object udp destination eq 7351
object-group network obj_Meraki_lan
network-object 10.2.11.0 255.255.255.240
network-object 10.5.11.0 255.255.225.240
object-group network obj_Meraki_pub
des This group lists all hosts associated with Meraki.
network-object host 64.156.192.154
network-object host 64.62.142.12
network-object host 64.62.142.2
network-object host 74.50.51.16
network-object host 74.50.56.218
object-group service obj_Meraki_outbound
service-object tcp destination eq 443
service-object tcp destination eq 80
service-object tcp destination eq 7734
service-object tcp destination eq 7752
service-object udp destination eq 7351
object-group network obj_Meraki_lan
network-object 10.x.x.x 255.255.255.240
network-object 10.x.x.x 255.255.225.240
object-group network obj_Meraki_pub
des This group lists all hosts associated with Meraki.
network-object host 64.156.192.154
network-object host 64.62.142.12
network-object host 64.62.142.2
network-object host 74.50.51.16
network-object host 74.50.56.218
I have tried tying all these groups together in multiple ways but cannot figure out how to do this. This what i think it should be "access-list outbound_access extended permit object-group obj_Meraki_outbound object-group obj_Meraki_lan object-group obj_Meraki_pub"
What i want is the use the service objects and the source network would be obj_Meraki_lan and destination would be obj_Meraki_pub. It seems the rules completely change when you use object groups. Can someone explain this maybe with a few examples. I am already using object groups in many acls but not for every element.
Thanks

Also have used such configuration in some special cases where the customer has insisted on allow specific TCP/UDP ports between multiple networks. And nothing is stopping from adding ICMP into the "object-group service" also.

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

Show access-list | include

Couple questions on show with include
1. Can you do a show command with include and a space meaning can you search for say "permit ip"?
2. Can you do a search for an exclude say "show access-list | exclude eq"?

Sure, examples:
How do you do the include for words and spaces?
When filtering you can use the underscore to refer to spaces on the lines.
Can you do a show command for access-list where you are looking for permit IP without "eq"?
You can't mix commands like, mixing "inc" & "exc". So no.
Besides, the only available option when using two or more pipes is only OR, in case you were wondering.
Now, examples
show run access-list test
access-list test remark hello world
access-list test remark helloworld
access-list test remark hey hello world
access-list test remark heyhelloworld
Now, filtering:
show runnaccess-list | i hello
access-list test remark hello world
access-list test remark helloworld
access-list test remark hey hello world
access-list test remark heyhelloworld
show run access-list | i _world
access-list test remark hello world
access-list test remark hey hello world
show run access-list | i hey | world
access-list test remark hello world
access-list test remark hey hello world
I think that covers it.

This comment is missing in "show access-list". So in the access list, for all the lines after this comment, the line number is no longer correct. This causes problem when we try to use line number to insert a new rule.
Has anybody seen this problem before? Is this a known problem? I am glad to provide more information if needed.
Thanks in advance.

BGP with access lists

Hello,
Can someone explain to me why we use access lists in a mpls cloud that uses IBGP. I thought for the most part access lists were used on firewalls not routers running BGP. Do we even need access lists with bgp can't bgp work without access lists. What are the reasons for having access lists on a router for IBGP on a mpls cloud?
Thanks,

The only way to get access to your network is if the ISP misconfigures so that another company gets access to your IP networks by mistake or that someone gets access to a PC on the inside and can reach the networks from there. It could happen if someone accidentally downloads an e-mail attachment or something like that.
It all depends on how critical the traffic is. If it's a bank there could be regulations in place that demands that all traffic is encrypted even if it is supposed to be private. If you compare it to a leased line, it's also secure as long as someone doesn't get access to it. So MPLS is like a virtual leased line in comparison.

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.

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
This link should help :

Pb access-list Catalyst 4507r

Hi
I have 2 vlan : 192.168.38.0 and 192.168.31.0.
In the 38.0 network, I have an exchange server.
And in the 31.0 network, I have a clients(microsoft outlook).
The pb is when i configure the access-list, the client start a 135 port communication but it don't have an answer.
But if i open the all port, it's Ok.
Here, my access-list.
Could you confirm if it's ok
in advance, Thank you

Hi,
Thank you very much.
When i see with the ethereal soft, the client need to open a range port(>1024).
Please give me the access-list
In advance thanks!!

IPSEC access-list question

Hi,
I have an access-list with the following line...
permit ip host 65.119.114.3 62.140.152.0 0.0.0.31
and its crypto ipsec sa shows up as this, with no packets encaps or decaps.
protected vrf:
local ident (addr/mask/prot/port): (65.119.114.3/255.255.255.255/0/0)
remote ident (addr/mask/prot/port): (62.140.152.0/255.255.255.224/0/0)

#pkts encaps: 0, #pkts encrypt: 0, #pkts digest: 0
#pkts decaps: 0, #pkts decrypt: 0, #pkts verify: 0
#send errors 0, #recv errors
I also show a crypto ipsec sa which doesn't correspond directly to my accesslist. This is the second time I've seen this... is there any part of IPsec where the access-list are shared with the other end? i didn't think so, but I'm not sure how we got this, if not.

Can you post the configuration from this device.

Strange access list debug output

I have a router interface configured with the following access list:
access-list 101 permit tcp any any eq 23
access-list 101 deny ip any any
effectively, telnet is allowed and all other protocols are denied. when I start a debug on this access-list (debug ip packet list 101 detailed) and start telnetting to the router, everything works (as it should). But when I look with "show ip access list" I see there are about 30 matches on the "...eq 23" rule, which is correct, but there are also around 30 matches on the deny ip any any rule. The debug output shows only port 23 traffic and return traffic.
My question: what packets hit the "deny ip any any" rule when starting a telnet session?

Hi
Could be a name resolution issue but the easiest way to check would be to change your second line in the access-list to
access-list 101 deny ip any any log

How to create a Access list on core switch to bloxk all Internet Traffic & allow some specific Internet Traffic

Hellp Everyone,
I am trying to create a Access-List on my Core Switch, in which I want to allow few internet website & block the rest of them.
I want to allow the whole Intranet but few intranet websites also needs access to the internet.
Can we create such Access-List with the above requirement.
I tried to create the ACL on the switch but it blocks the whole internet access.
i want to do it for a subnet not for a specific IP.
Can someone help me in creating such access list.
Thanks in Advance

The exact syntax depends on your subnets and how they connect to the Internet. If you can share a simple diagram that would be much more informative.
In general just remember that access-lists are parsed from the top down and as soon as a match is found, the processing stops. So you put the most specific rules at the top. also, once you add an access-list, there is an implicit "deny any any" at the end.
The best approach is to create some network object-groups and then refer to them in your access list. From your description, that would be something like three object-groups - one for the Intranet (Intranet), one for the allowed servers that can use Internet (allowed_servers), and a third for the permitted Internet sites (allowed_sites).
You would then use them as follows:
ip access-list extended main_acl
permit any object-group intranet any
permit object-group allowed_servers object-group allowed_sites any
interface vlan
ip access-group main_acl in
More details on the syntax and examples can be found here:
