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.

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. -
ASA 5505 version 9.1(4) NAT issue
Hi,
I am using ASA 5505 version 9.1(4) and using dynamic NAT command to NAT(PAT) inside subnet 192.168.3.0/24 with outside interface 192.168.100.2/24
But unable to ping from inside host to internet or router interface 192.168.100.1 . Please suggest the show running is mentioned below.

ASA 5505 version 8.2 Base License - getting more anyconnect licensing
Is it possible to increase the number of IPSec VPN peers from 10 to 25 on an ASA 5505 version 8.2 with the base license, simply by adding
L-ASA-AC-E-5505= and not having to upgrade to the security plus license?
ASA 5505
Base License: 10 sessions (25 combined IPSec and SSL VPN1 ).
Security Plus License: 25 sessions (25 combined IPSec and SSL VPN1).
Thank YouI tried reloading the ASA but to no avail. The ISP cleared their ARP cache as well.While I had the ISP online and they didn't see the printers DHCP request.
Of course this is all remote but I can see the interface state change when I have the users turn the printer off then on. When I plug the printer into the local LAN it obtains a local DHCP address and I can access it.
So I'm thinking the printers DHCP request is being blocked at the ASA or somthing else is causing the issue. I am at a loss. -

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

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 -
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 -

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.

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 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?
ThanksYes, 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

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!!

Cisco ASA 5505 VPN help for local lan access.
Hi all,
I am very new to Cisco systems. Recently I was tasked to enable local lan access for one of my server. The problem is this. I have this server with 2 interfaces. One interface to my FTP server(192.168.2.3) and the other to the Cisco ASA(192.168.1.1). Whenever I connect the server to Cisco Anyconnect VPN, I am unable to access the FTP server anymore.
I googled and found out that the problem is because the metric level is 1 for Ciscoanyconnect network interface which causes all traffic to go through the Cisco VPN Interface. Another problem is I can't change the metric of the Cisco VPN Interface as whenever I reconnect to the VPN, the metric resets back to 1 again. I tried to follow some guides to configure split tunnel but my traffic is still going through the VPN connection.
Anyone can tell me what I am missing here? Sorry I am very new to Cisco systems. Spent about 5 days troubleshooting and I feel I am getting it soon. Anyone can guide me what else I am supposed to do?
What I did> Configuration>> Remote access VPN>> Network Client Access>> Group Policies>> Advanced>> Split Tunneling>> Uncheck Inherit and select "Exclude Network List below.>> Uncheck Network List and select Manage, Add 192.168.2.0/24 to permit.
Really appreciate if anyone can tell me what else I can do to ensure my server has access the my FTP Server after connecting to the VPN.
Thanks all!
Wen QiHi,
Try adding the following configuration
policy-map global_policy
class inspection_default
inspect pptp
And then try again.
I'm not 100% would you need to perhaps allow GRE through the firewall even after that. (Protocol 47)
