I accidentally setup two schedule rules both with the name of "Log". When I highlight either rule, and try to delete either, I get error "The rule is being used by another rule and cannot be deleted" How do I delete?
View 1 Replieswhat is the purpose of the "Permint all traffic to less secure networks".
Well I know the purpose and the technique to handle some sercurity level is nice. when I cannot add add a rule without deleting this implicit rule?
The technique of security level is then obsolete?
I need to block incoming traffic with Dlink DIR 600. I know how to create the rule source (WAN) to destination (LAN) to deny all protocols. But what IP will I put in WAN? IP address of my Internet? Or how can I enter the ALL IP range in source...format for the IP (it's not 0.0.0.0).
I want to do this because in the DIR log section I'm being PING Flooded. I already un-check "Enable WAN Ping Response" but still receiving the message.
Using a DIR-655, does anybody know how to create a firewall rule to block all dns requests except to specific servers?

ezvpn client works fine for normal users that want to just authenticate with the Cisco vpn client. i have a site 2 site setup from the pix to my house, the connection is "up" on both ends, i see phase2 initiate under the pix logs . try to ping nothing happens, even drop down the byte size and the DF bit (aka ping xxx.xxx.xxx.xxx -l 100 -f ) ping to the next routed interface hop and i get "no translation group found for icmp src outside: xxx.xxx.xxx.xxx <--- my internal network dst inside xxx.xxx.xxx.xxx <---- pix internal network .
Am i missing a NAT rule on the pix or the 1841?
so I have my router that's connected to outside world (internet) and it's also connected to my company.I want to create a nat rule that basically says when I go to my company don't nat but when I go on the internet nat.now I do this with this statement [code] I want to do the same thing but this time with this rule. ip nat inside source static tcp 10.181.20.84 22 interface FastEthernet4 2222 this rule doen't work from the company to my router but it works from the internet to my router...
I just can't find the way to change this ip nat rule and use my same 110 ACL.basically with this last rule when I try to connect to my router from the company it tries to nat it back to the ip of the router interface ... it should not nat when I go from the company but nat when I connect from the outside internet.
we have a RV082 and have the DMZ option enable for a range of IPs within the same subnet of WAN IP and this works great. I have another range of Public IPs from our ISP that is not in the same subnet of the WAN IP and do not see a way on the RV082 to include this 2nd bank of Public IPs in the DMZ. Our ISP internet feed plugs into the RV082 WAN port and we have a switch pulgged into the DMZ port of the RV082 that is used to connect the public devices in the current DMZ. Both banks of Public IPs from our ISP come over via the ISP internet feed plugged into the WAN Port. My question is, if I cannot configure a DMZ rule to allow this 2nd range of Public IPs to "travel" to the RV082 DMZ port.

Ive had a look around and cannot see any options, the server team seem to think its not possible to have this triggered from AD either on a side note, where are the SMTP settings on the ACS?
ASA 5510 running without issues for a while but we needed extra port so added a 4GE SSM.
Having installed the 4GE SSM we had some issues with the card not liking a connection to our switches and only working by plugging directly from the server into the firewall, not great as we wanted extra servers on the line in the future. So we upgraded the firmware and no are at an impasse.
We have upgraded to 8.0(4)3 and now we cannot get any traffic through the port, we can't even connect to an external DNS server. Running a packet trace I get an immediate error on the first step '(l2_acl) FP L2 rule drop', and it appears as though the outside connection is down.
I have some experience on setting up basic port forwarding and NAT for internet access, webservers, mail but this has thrown me.
Our external security department needs to scan, every three months, a computer behind the firewall. I need to create a simple NAT rule that will allow an ip address or subnet to the computers behind the ASA 5505. At the moment, we have a simple NAT rule which allow all network traffic to exit from inside to outside.

View 1 Replies View RelatedI just installed a new ACS 5.1 to authenticate wireless PEAP users, so I created an Access policy "WirelessUsers" with identity store being Windows Active directory and all domain users are selected, and create a service rule that dictates that if the authentication protocol is radius, network device belongs to WLC device group, the result service will be "WirelessUsers", so this part worked perfectely, all domain users are able to gain wireless access via their DOMAIN/usernames and domain passwords. Now I want ACS local indentity store users (those local usernames can be the same or different from their AD usernames) to be able to manage those controllers, so I created another access policy "DeviceAdminUsers" with identity store being local users, another service rule which says that if the authentication protocol is radius, network device belongs to WLC device group, the result service will be "DeviceAdminUsers". The problem is that with the setup, whenenve when I try to SSH to WLC, ACS always put me in "WirelessUsers" access policy, even the login name does not have DOMAIN pre-pended or the login name simly does not exist in AD. if I put the second rule in front of first rule, I am able to authenticate with ACS local username/password and gain access to WLC, but wireless users will fail to authenticate, because ACS is trying to put regular wiress users in "DeviceAdminUsers" access policy. I would expect if username does not exist in AD, ACS should proceed with next rule. Similar requirement was easily achieved in ACS 3.3.

access-list lanB_acl line 1 extended permit ip 192.168.99.0 255.255.255.0 any
access-group lanB_acl in interface lanB_interface
But when I tried to reach a host in the lanA, the packets are dropped. I configure the asdm, which shows this on the LanB interface:
1 lanB_network | any | ip | permit (hits 344)
2 any | any | ip | deny
and I checked the packet tracer with: tcp, source: 192.168.99.57:10460 dest: 192.168.12.2:443 and it shows that the packet has been dropped by the last 2. 'implicit any any ip deny' rule, in spite of my access-list rule (access-list lanB_acl line 1 extended permit ip 192.168.99.0 255.255.255.0 any) preceded it, and active.
The lanB and lanA interfaces are the same security level 100, and I can reach the outside/internet from 192.168.99.57 Is it possible that I have to reload the rules or something like in order to apply? Or I missconfigured something?
I am creating access rule on a ASA5520 running ASA 8.2 (1) and ASDM 6.2(1) and found that the GUI has less option then when creating access rule on a ASA5505 running ASA 7.2 (3) and ASDM 5.2(3) (see attachment). Is there an option that enables me to get the same configuration options on the ASA5520 running ASA 8.2 (1) and ASDM 6.2(1) as I have on the ASA5505 running ASA 7.2 (3) and ASDM 5.2(3).

i am trying to find out if it is possible to have a translation rule fail over to a second server if the primary is down on my cisco pix515e.so for instance having an external ip address of 82.x.x.x mapped to an internal ip of 10.x.x.1
If 10.x.x.1 is down then 82.x.x.x should be mapped to 10.x.x.2.The reason i am asking this is i also have 2 css11501 load balancers and would like to have our staging servers primarily sat on one with secondary connectioin to second, production on the other failing over to each other if one is down. The load balancers will be connected to different ports on the same firewall.
I picked up an RVS4000 V2 and configured a rule to forward a Magic Packet to an internal system to wake it from a sleep state. Everything was working fine until I update the firmware to v2.0.3.2. I know it's not the the computer as I can wake it from Sleep internally without any problems. One thing I noticed is that the static IP for the computer in Sleep state gets lost in the ARP/RARP Table though the NIC is configured to respond to ARP requests in Sleep.
Has anything changed in v2.0.3.2 that requires a different configuration to get Wake on Lan working externally?
My Setup is
Computer
P8Z68 Deluxe/Gen3 onboard Intel 82579V NIC
Wake on Magic Packet: ON
Respond to ARP/NS requests without waking system: ON

View 4 Replies View RelatedI got a Global Implicit Rule problem with my Cisco ASA 5510.

Why is there only one Global Implicit Rule, and not one for each Interface (like in the older versions of ASA OS) ?
Can you set the ASA 5500 series to learn the rule itself? I am talking about putting it into learning mode for first few weeks. I have done this with Zone Alarm software, but not sure this is available in Cisco 5500 series.

I have a DSL line at work that we use to test external services provided to external users on our primary Internet circuit (Citrix, web applications, etc). Because this DSL line is for testing only, we want to lock it down so the only destinations allowed through the firewall are our own IP spaces.
I purchased a WRVS4400N for this purpose, thinking I could use the IP based ACL list to create these restrictions. However, every time I try to create an ACL, the internet slows to a crawl, and many sites don't come up at all. This occurs even if the ACL rule I add is a simple "allow any any" rule similar to the default rules.
Is this a known issue, or am I configuring something incorrectly? Here's an example of a rule I'm using (IP not real):
Action Service Source Interface Source Destination Time Day
Allow All Protocol LAN ANY 1.2.3.0/255.255.255.240* Any Time Every Day
I also get the problem with a simple allow from a single IP (mine) to any destination, without any other rules enabled.
implementation of the ACL ruleset on these routers?
I am trying to add 89,462+ access list rules to an ASA 5510 running 8.2(5). I have added all the rules to an object group and when I try to apply the access list to an interface it gives me the following error:
ERROR: Cannot add policy to rule engine ERROR: Unable to assign access-list wan-out to interface wan
I have not tried not using an object group and just putting the rules in the access list. I want to be able to add to these rules if needed easily.
I think it's clear that i have exceeded the rule limit for the ASA. So my question is, what is the rule limit for an ASA 5510 and which ASA could I purchase that would handle this amount of rules?
I have two questions about ZBF on ASR1000 with Firewall and Flexible Packet Inspection license:
1 is IPv6 supported?
2 can I use police action in an inspect rule? I want to limit some protocols to low bandwidth. There is no police command in ZBF policy map.
I have an ASA5505 that I am setting up behind another firewall. The external firewall has all ports forwarded to the ASA which is fine as I can see the traffic getting to the ASA in the log. However when the traffic trys to return to it's destination the ASA assigns a random port number. For example for VPN the source port is 443 but when the ASA trys to go back to the public IP addess it is using port 52857 which is obviously blocked on the external firewall. The Packet Tracer also says the the traffic is blocked by an implicit rule on the ASA which denys all ip traffic however I can't delete this rule and as I test I have created another rule allowing all IP traffic.
View 2 Replies View Relatedwe have a nat exemption rule for 10.0.0.0/8 to w.x.y.z followed by some static nat rules and then dynamic policy nat rule for 10.0.0.0/8 to w.x.y.z natting to IP a.b.c.d.When I do a packet trace from 10.10.10.10 to w.x.y.z, it shows the packet first matching against the nat exemption rule, and then immediately afterwards it matches the dynamic policy NAT rule. The static nat rules are being successfully bypassed (which is what I want), but why does the dynamic policy nat rule apply if an exempt rule has been hit already? An actual test between the IPs above reflects the result of the packet tracer as well (IP a.b.c.d is seen on server w.x.y.z).We are running the following software on an ASA5520.

I have one ASA 5510, a primary ISP (cable, the single public IP lives on the ASA), and a backup ISP (ADSL, separate router that hosts its single public IP). I use IP tracking to detect link down on the primary. When I pull the plug on the cable modem and go to "Route monitoring", I can see the ASA's default route is now the backup ISP default route.That conforms with [URL] Pings to 8.8.8.8 fail however, and when I do a packet trace the ASA complains about the dynamic nat rule that still points to the primary ISP's interface.Only when I change the existing dynamic NAT rule (on my inside interface) to use the backup ISP's pool (which is a single 192.168.x.y address) , does 8.8.8.8 reply to my pings. So it kinda works but it's not full auto . I can't add a second dynamic nat rule on the same inside interface, nor can I select 2 IP pools in a single dynamic nat rule.
View 4 Replies View RelatedI have found this in documentation (the same statement for version 8.3 and 8.4):
" Access Control Implicit Deny #All access lists (except Extended access lists) have an implicit deny statement at the end, so unless you explicitly permit traffic to pass, it will be denied. For example, if you want to allow all users to access a network through the ASA except for one or more particular addresses, then you need to deny those particular addresses and then permit all others.

Does it mean that now all ACLs shoud have created manualy deny ip any any rule at the end ? I have migrated one ASA to version 8.3 (no host connected and I can't test it) but after migration I don't see this rule at the end of all ACLs. Does it mean that all traffic will go throu ACLs on all interfaces ? I didn't find any information about this change in documents describing new software features [URL]
