On a Cisco ASA 5520. I have 2 interfaces that are the same security level. I need hosts on 1 of these interfaces to be able to get to a specific IP and port on the other but I DON'T want to blanket enable 'same-security-traffic permit inter-interface" I have added an ACL inbound on the interface allowing the desired traffic and inbound on the other for return traffic and it simply doesn't work.
interface GigabitEthernet0/3.175
vlan 175
nameif Test175
security-level 30
ip address 172.30.175.1 255.255.255.0

Verifying the operation of the ASA when configured with Global access rules. Does the global rule overide the interface security levels? According to the ASA order of operations, the interface specific rule get's processed first and then the global rules, but It does not say anything about interface security levels. Observing an ASA in production that has global rules configured I see that an interface with a security level of 50 that has no rules applied to it, passing traffic to the outside interface (security level 0) drops the traffic. Syslog shows that it hits the global access rule implicit deny. Does the implicit permit any to any less secure interface not apply?

View 3 Replies View Relatedwe have a Cisco 3825 router which does not work well with a DSL modem(ISP provided). I have configured the Gi0/0 port of the router to plug into this DSL modem but it does not ping to the ISP gateway. If we do a shut/no shut on the interface then it work fine for about 30 secs. Sometimes even for 1 hr. Then the packets drop and we cannot pass any traffic through this interface.
Now, if the ISP connection is terminated on a computer it works fine. It works fine without dropping any packet.I have tried various options like using a straight/cross cable. I have tried to configure the interface negotiation for 100/full, 100/half, auto/auto and almost all the options.I have also tried to interconnect the devices using a L2 device like a HUB. Nothing works.
our customer unfortunately uses a Watchguard.Finally we could establish a site-to-site vpn connection.To test if the connection re-establish again, we cleared our vpn session by "clear crypto isakmp <session id>" and after that "clear crypto sa <ip address of the peer>"After that, the session is down on our site, but the watchguard keeps the Phase I still up, either the deleting messages from our cisco are visible in the watchguard log files.Watchguard helpdesk told us, that the messages are only seen as a deletion message for Phase II, therefore Watchguard keeps Phase I up and running.Here you could see the cisco 7206 log messages aftre the clear commands:
: Nov 10 13:22:06.508 MEZ: IPSEC(delete_sa): deleting SA,
2011-11-10 13:22:06 Local7.Debug 649460013: : (sa) sa_dest= <local peer>, sa_proto= 50,
2011-11-10 13:22:06 Local7.Debug 649460014: : sa_spi= 0xEB0AE65A(3943360090),

2011-11-10 13:22:06 Local7.Debug 649460016: : (identity) local= <peer>, remote= <peer>
[code]....
In my opinion, it looks ok and we do not have problems with other VPN devices with this kind of tests.what could be done that the watchguard deletes Phase I, too? Or that an explicit Phase I deletion message is created and sent by our cisco 7206?
I have two 3825's. Each has it's own ISP connection. Nat is configued for both. They have an ethernet connection between them and I'm running OSPF between the two so the routes propogate. I have qty 11 Dialer interfaces configured on each router (each router has an exact copy of the other routers dialer interface). However, I only want the Dialers up if the ISP connection on the mated router goes down. Much like HSRP I need one to preempt and be active if both ISP connections are up. When one goes down the other Dialers must come up. Each dialer sends a Dynamic DNS host name and IP address pair to DynDNS.org. So I cannot have both up otherwise the DNS names will bounce between ISP#1's IP address and ISP#2's IP address (back and forth). Let me know if any option exists to make this happen. As an aside the ISP's are providing me DHCP addresses so I cannot work off of an IP, it has to be the physical interface (i.e. Gi0/0).
View 1 Replies View RelatedI have ASA 5505 that has two inside security level 100 interfaces and an outside interface.On the inside interface we have corporate domain subnet with DC and 30 hosts. On the inside2 interface I have few servers that runs specific application important for our business needs, and dumb terminals that are connected to them.I have a laptop user that periodically needs access from our corporate vlan1 to one of the servers on inside 2 vlan via remote desktop or some other remote viewer client,so he can view reports etc.I have enabled same-security-traffic intra-interface command and added nat exempt command pointing specific laptop host machine to that specific server.
Now my main concern is regarding security. This user carries his laptop home, browses the web, puts USB memory, and you can imagine how this machine is susceptible to all kind of malicious software. Inside2 vlan is very important and until now it has been a very secure environment.This is no longer the case since all traffic between this inside sec level 100 vlan host and corresponding inside2 sec level 100 server is now allowed because of the enabled same level interface traffic and nat exemption rule. Do I have another solution that would allow communication based on just a tcp port number for this host? Something like port forwarding from outside to inside Vlan interface?
I have 2 dmz interfaces(dmz1 and dmz2) with security level 50. I am able to ping the hosts on dmz2 from dmz1. I am running a service on a dmz2 host on port 82 but i am not able to access that service from dmz1. Also, i have an inside interface at security lever 99 which is able to access that service.
Also, i have defined the following command to allow same security level communication.
same-security-traffic permit inter-interface

I tried to access server from THREE network to web server at FOUR network I have no response. In sh xlate output it shows "PAT Global 10.124.104.254 (28889) Local 10.124.103.1(2922) " I am not sure what else should I do. I add both same-security-level commands and it is the same.
Quote from the RV180 manual; 'By default, all access from the insecure WAN side is blocked from accessing the secure LAN, except in response to requests from the LAN or DMZ.'
Does this mean a general access-rule for the firewall blocking all inbound (WAN --> LAN) data is not required?
I'm trying to implement some best practices for ASA running on Software Release 8.2 and had a question about the default security-level behavior. Let's say I have 3 interfaces...
-inside (security-level 100)
-dmz (security-level 50)
-outside (security-level 0)
I have an ACL on the inside interface allowing http access to anywhere. Because of the ACL, the implicit higher to lower security level access is nullified. Correct?
I do NOT have any ACL on the dmz interface applied. So, would the servers in the dmz be allowed outbound access to the Internet due to the default higher to lower security level behavior?
We have an ADSM (version 5.2(3) ) . In ASA ( version 7.2(3)) we are working with routing, access restriction and configuring IPSEC vpn with integration to our AD. We need to get two diferent profiles: one for networking administrators, who are going to manage routing, acls and have the root for ASA, and the other profile is going to be for the vpn administrators. As I read from the ASDM 6.0 user guide is posible define command privilege level. So do you consider posible to define a particular level for all the command related with ipsec vpn (Create, Modify and Delete) and asociate that particular level with the user for vpn administration.
View 1 Replies View RelatedI'm facing a problem with two vlans. Each vlan has internet access by NAT.
In each vlan there is at least one server, who should be accessible from the other vlan and vice versa.
The function "same-security-traffic permit inter-interface" doesn't work, because NAT control is in place - so an expert.
Some experts told me it's not possible to route back out the same interface, and also not route back out the seperate subinterfaces as well.

I have ASA 5585 with SSP20. I want to enable same security level subinterfaces (routed mode) to communicate with each other.
I have put below command at global level but somehow it is not happening.
hostname(config)# same-security-traffic permit inter-interface
Do I also need to check for NATing or some other things apart from above command?
I have been monitoring the alarm summary but have been off couple days and i see one of my controllers is down.

I need to understand security bundles. I purchased a Cisco Security Bundle, Advanced Security, 64F/256D. part number CISCO3825-SEC/K9. My expectation from this device was that I will get an IOS based firewall with no need for an additional firewall module. however, the supplier is telling me that I have to buy a firewall module to use the feature. Isn't the bundle supposed to come with all I needed since is a bundle?
Is there any command I can use to verify if this device is really what I paid for? what can can I check for in the sh inv and sh ver commands? I don't see any information from these commands.

View 7 Replies View RelatedI have my main branch router (3825) and two remote routers (2821's). They are connected through leased lines that do not touch the internet. For various security reasons I have to ensure that the traffic from the remote's are encrypted in a VPN tunnel even though it is still part of a private network.I have went ahead and created the tunnels and I can verify that they are up. I have applied the cryptomap to the correct interfaces, etc.So the question is - How do I ensure that traffic is not just being router out of the interface from the remote sites back to the branch router with or without using the VPN tunnel? I've taken down the tunnels and of course, the traffic is still being passed back and fourth.

I'm having an issue with my laptop. Although, from my provider, it should be possible to establish a connection at 25'000 kbit/s (download), max speed is at about 800 kbit/s. I'm only about 20 feet away from where the router is located and I don't use any phones (except for a cell phone). I read on this board, that I might have to change the wireless settings on the router and change the radio band but didn't manage to do so. I'm using Mac osx and a wireless connection.
View 4 Replies View RelatedPurchased E2500 1 week ago. I do not have a problem communicating with the router itself (either hard wired or wireless) but I have been unable to establish a usable internet connection from the router.I live in building that is wired by Restech Services - Ethernet jack in wall - no modem. Connection works just fine if I bypass router and connect directly to PC (windows XP SP3 desktop or windows 7 laptop.),Very difficult to establish any internet connection at all. I have to renew IP address many times or go through re-boot sequence multiple times. Once I get a connection it is unusable. If I attempt to ping a URL (either from PC or from router admin page) it is unable to resolve host. If I ping an IP directly (either from PC or router administrator page) I typically get 60 to 80% packet loss. As noted, if I bypass router and make internet connection directly to PC - no problems - no packet loss.Used Cisco Connect software to set up. On advice of ISP changed MTU from 1500 to 1300. Also registered MAC id with ISP and changed from cloning PC MAC to using the router MAC. Downloaded and installed latest firmware version. Did factory reset and re-configured the whole thing. Double checked and swapped wiring.

I have a new EA3500 router that's working great for a variety of devices* except a Windows7 laptop. 24 hours after establishing a connection, the laptop loses connectivity and it's very difficult to re-establish a connection. Usually I have to reboot the router, but 24 hours later the problem returns and Windows is unable to connect.
My router settings include DHCP client lease time set to 1440 minutes (24 hours), so I thought the problem might have something to do with DHCP lease renewal. To test this theory, on Saturday night I did ipconfig/release and ipconfig/renew and established connectivity from the laptop.
Sunday morning I spoke with Linksys support and changed several settings per their recommendation:Network mode mixed (I had it on N-only for some reason)Assigned different SSIDs to the 2.4GHz band and 5 GHz band2.4 GHz band channel is 20MHz only, using channel 95 GHz band channel is 40 MHz only, using channel 161I also power cycled the router. Everything worked fine until Sunday night, 24 hours after the release/renew, when I lost connectivity. I am not sure what to try next and whether the problem lies with the router or the laptop.
On my PC laptop, when we try to connect to the internet (wireless router) through firefox we get the error message"Firefox can't establish a connection to the server @ cn-us.start3.monzilla.com. When we try using Window explorer we get "Internet Explorer can't display webpage" When prompted to click on "diagnose connection problem" it states Windows did not find any problems with this computer network connection.
A couple of points... the connection indication at the bottom states the laptop is connected to the internet. (WLAN ON)I have a Mac that is connected to our internet and doesn't have any problems.We have Windows Vista on the PC laptop
I too am having a problem establishing a secure connection for Dropbox, Adobe update and just about every website I try to access via Firefox or Chrome comes up as unsecure. I can add exceptions, but I would rather access them securely.
