We're currently PATing everything from a particular subnet to the IP of an outside interface using our ASA5585 (dynamic PAT). We're experiencing pool exhaustion and therefore need to expand the global IP range. Any way of cutting over to the new range without dropping existing connections? For clarity, the current interface address is x.x.x.37/22 and the new PAT pool is x.x.x.114-6/22.
View 6 RepliesGot an ASA5520 running V8.2(3) and we want to upgrade our internet bandwidth. Our ISP says OK but we need to install different physical circuit, upgrade CPE router, etc.
Then they say, btw your globally allocated IPs will change - this is a problem as we have Site-to-Site VPN Tunnels, IPSEC RA, etc.
ISP are proposing to give us a 3 month period whereby old & new IP blocks will be routed to our ASA (by means of secondary IP address on their Cisco CPE).
Multiple IPs on the same physical i/f on the ASA require sub-interfaces/IP Addresses/VLAN ids on my "outside" i/f.
Is this going to horiibly break Site-to-Site VPN Tunnesl, IPSEC remote access ?
Will VLANs work at all with IPSEC on the "oustide" i/f at all ?

I have an ASA 5510 running version 7.0. I have a problem with an exchange server using a static map and its outbounc connectivity. It connects outbound through the global address even though inbound connectivity works fine through the static mapping. The recent changes are changing of the zero route through a different interface (there are to circuit connected to this ASA on different interfaces). So the idea was to get all workstations in the office using the global address and routing out through one circuit, and the servers connecting in/out through the other circuit. Shouldn't a static mapping ignore what the zero route is?
Here are what I believe to be the relevant configs.
interface Ethernet0/0
description New 6mb circuit
speed 100
[Code]....
So exchang2 server can be connected to from the outside properly via IP xxx.207.51.231/exchange2-outside, but all outbound connections from this server are going out via IP xxx.122.47.218/circuit-6mb as do all the workstations due to the global address statement.
I am interesting how ASA 5585-X with SSP-60 operates in dual firewall mode, if I install two SSP-60 modules in chassi, do I get one logical firewall with doubled performance of (SSP-60) ?
View 1 Replies View RelatedI have an ASA5505 with 8.4 software used on a business DSL account.This means I am running PPPoE session to the provider and am then given an Inside Global subnet /29.I have various servers NATed to specific IP's then have the DHCP users NAT with overload to another of my inside global addresses. When I try to establish an IPSEC tunnel to any of my inside globals and monitor I get an access denied message but there is nothing that is blocking.If I determine my PPPoE IP address I am able to extablish a IPSEC session to that but cannot exchange traffic. Not that I want to use that IP anyway because that PPPoE Session IP changes and only my inside globals are static.I spent several hours on this and cannot put my finger on it. Do I need to allow VPN to the INSIDE interface?

I used to have a Thomson st-330 USB modem for my ADSL network. When I wanted to change my IP i just disconnected and reconnected a dial up connection that does the job instantly! (a wan miniport + a batch file to disconnect/recoannect with my password and username)Few days ago i bought a new modem/router (TP-LINK TS-W8951NS)Before that all I knew was that if I wanna change the ip address (if I have a router) was a batch file with commands ipconfig /release/renew.I now know that this changes the ip of my PC not the global IP! So how would I change it without restarting the router? (When i change something in my router interface page (PVC1.2.3....etc) my IP changed instantlybut how do I do this without accessing the router, like commands and a batch file etc? I just found out that my global IP changed on its own after like 30-60 min :S why is that! and to do so manually???

I got some issues with my CISCO ASA, the thing is that when I add a new rule on the device this rule duplicate and goes to the bottom. We already tried to delete the duplicate rule but it always show an error.
-Model 5585
-ASA Version: 8.2(5)
-ASDM version: 6.4(5)
I've been having a major problem with our Internet service. Our ISP insists it's the firewall.
I'm not a Pix expert by any means, but here's what's happening:
- Our Internet service drops.
- When this happens I try to ping the PIX on the inside interface and it times out.
- Our Internet service comes back up and I am able to ping the Pix.
- I connect to the Pix and issue a SHOW INTERFACE command to look for errors. I FIND NONE.
I have ASA5585 Firewall between my WAN Cloud and LAN Network. I plan to configure Layer 3 Vlan Interfaces inside FW and it would be Layer 3 gateway for some of Subnets. Layer 3 VLAN Interfaces are planned to be dual stack containing both IPv4 and IPv6 Address stack.
I plan to configure 6 to 4 Tunnel with my Hub Site where we have native Ipv6 awareness. One tunnel end point would be ASA and the other endpoint would be Hub site WAN Router/L3 Switch. So IPv6 traffic hitting to vlan interfaces on ASA would be policy checked and routed over tunnel interface to Hub Site.
6to4 Tunnel manual tunnel configuration on ASA. I have configured such tunnel on L3 Switch or Router with following config.
Int tunnel xyz
ipv6 address <ipv6 address>
ipv6 enable
tunnel source <loopback address of my L3 Switch>
tunnel destination <loopback address of my hus site L3 Switch/Router>
tunnel mode ipv6ip
end
I need to implement something similar in ASA. How can I do that?
How do i measure the total throughput going via 5585-X.It has the firewall througput of 5Gbps. Looking at aggregate of all the interfaces traffic going through it seems about 4gbps is going through.
I use show traffic command and add up the trasmit and receive traffic on each live interface.Is that correct method and are there any more commands?
I am having a problem with a ASA 5505. The users on the inside cannot access internet for the most of the time. When i looked over the configuration and tried a few changes i got out to internet about 5 seconds every 30 minute or so. Very strange. When i try to access internet i just get the windows post that DNS is not working properly. As you can see in my config i get all addresses dynamic from ISP.
I am not sure what to do next, i tried to set static routes, make Nat changes, static dns addresses, searching this forum but nothing works. It seems like there is a ISP problem but i have talked to the support twice today and they say that all is fine from their side. Does ASA behave like this?

use of a pair of ASA 5585's in active/active mode with a shared outside interface.Last time I did this was with FWSM, there was a restriction where all contexts that share an outside interface have to be in the same failover group.Does this apply also to the ASA? My thought is that it will, but I am unable to find that in any documentation.
View 1 Replies View RelatedRunning ASA5585’s in active/standby across a local campus MPLS network. Supported design, leading practice etc. Specifically our design is that two ASA5585 are configured as active/standby through a local campus MPLS network over 10gig links through ASR9k etc. The ASA’s are providing inter-vrf routing capability only with p2p l2vpn circuits configured for each logical interface between the ASA over MPLS etc.The failover link is via a direct fibre and the state link will be through a p2p l2vpn (option for direct fibre also)Is this a supported design to begin with?
View 2 Replies View RelatedI have a ASA5585 running 8.4 that is redirecting Internet http to a websense server via GRE.The integration is working fine, except when a user PC sends a large packet (~1500 bytes).With WCCP/GRE headers, the user packet is too large to be transmitted to websense, so the ASA fragments the packet in two and transmits both to websense.
A sniffer trace confirms that both fragments reach the websense server, but the TCP packet is never acknowledged.User-side TCP retransmits the large packet three times over 15 seconds, and eventually retransmits fine with smaller packets. The 15 second delay is of course not acceptable.Users and Websense server are both on the Inside interface.
We are considering imposing browser proxy to websense (which works fine), but would prefer not, considering the increasing diversity of devices.
We are experiencing intermittent issues with the IPS on our ASA5585 vs 8.4(2). Probably something with the dataplane. So I want to keep debug cplane 255 activated and logged with log debug-trace setting to syslog server. But when session times out the debug command is cleared so the output stops. Since it is a intermittent issue I want to keep debug activated...Totally different behaviour then with routers which keeps it activated. how to keep debug activated on a ASA.

I have two ASA in failover with Active/standby configuration. When I switch from standby to active from the standby ASA I get a lot (like 100) of error messages like these below: [code] The failover works fine and nothing seems to be wrong with the firewalls function.
-Hardware is ASA5585-SSP-10.
-Software version: ASA 8.2(5),
ASA is in multiple mode with 17 active context. Why these error messages appear and what they mean?
We have pair of ASA5585 (ver 8.4(4) with IPS module configured with Active/Standby failover. There are total 09 interfaces are connecting to different zones in the firewall and out of which three(3) interfaces are connecting to Palo Alto 2nd layer firewall. When we test the failover whatever interfaces not connecting Palo Alto failed or shutdown, ASA triggers the failover to other unit, however the Palo Alto is not detecting this failover and it still keeps its previous Active Palo Alto to pass traffic, thereby failing passing traffic on Active firewall through Standby Palo Alto firewall.
But when there's a interface failed or shutdonw on the interfaces where PaloAlto also connected, then once the ASA failover triggers and the same time Palo Alto also trigger its failover then both new active firewall and Palo Alto sending traffic through firewall.However we we cant all the interfaces of ASA also to connect Palo Alto and let the Palo Alto to inspect all the interfaces, but we need our ASA to work in a situation where any of the interfaces failed, the failover to work smooth the pass the traffic via either Palo Alto device.I just need to know is there anything tricky that we can configure on our ASA in this failover senario, or to confirm if there's no any workable solution to this situation.
I have attached the senario that I explained above. Just to emphasis the issue again, if any interface of Gig0/0, Gig0/4 or Gig0/5 failed on active firewall, ASA switching to standby firewall and act as Active, but Palo Alto still remains his Active state and the new Active ASA is not passing traffic via standby PA as its not detecting any of its interfaces as failed or unreachable..?
I just recently purchased a Cisco ASA 5505 ASA ver 8.2. I run a teamspeak server/ssh/dns and domain on the same server on the network.

I have a Cisco ASA running 8.2 in routed mode.The ASA has three interfaces, inside, outside and DMZ. They connect to the following three networks:
Inside: 10.1.1.0/24
Outside: 10.1.2.0/24
DMZ: 100.1.1.0/24
I have the following dynamic PAT configuration:
nat (inside) 1 10.1.1.0 255.255.255.0
global (outside) 100.1.1.1
nat control is turned off.
By my understanding any traffic from the inside to outside interface will be PATted to 100.1.1.1. However, communications between inside and the DMZ will not be PATted, and should work with no problems.This seems to be corroborated by this document: [URL]Which states:"The adaptive security appliance translates an address when a NAT rule matches the traffic. If no NAT rule matches, processing for the packet continues."EDIT: I may have misunderstood the above statement.I found this guide to configuring NAT/PAT: [URL]It states:"When you specify a group of IP address(es) in a nat command, then you must perform NAT on that group of addresses when they access any lower or same security level interface; you must apply a global command with the same NAT ID on each interface, or use a static command. NAT is not required for that group when it accesses a higher security interface because to perform NAT from outside to inside you must create a separate nat command using the outside keyword. If you do apply outside NAT, then the NAT requirements preceding come into effect for that group of addresses when they access all higher security interfaces. Traffic identified by a static command is not affected."My problem is that packet tracer does not seem to bear me out. It tells me the packet is dropped due to "no matching global" when I source traffic from the inside interface and send it to the DMZ.
I got a Global Implicit Rule problem with my Cisco ASA 5510. Here's my configuration : url...I created a PAT translation so that my web server (group LAN Network) could be accessed from the Internet.Although every rule seems to be ok, i got a "tcp deny access" when i try to telnet my public IP on port 80 (ping is ok).
Why is there only one Global Implicit Rule, and not one for each Interface (like in the older versions of ASA OS) ?
I have a work computer...Dell Latitude 6400, AT&T Global Network Client (Company VPN service), using Novatel USB551L from Verizon, with their new 4G LTE. First connect to Verizon, then it automatically launchs ATT Global Network Client, once connected, the system automatically maps drives. I stay on for about 15 minutes average to 40 minutes that's when the Verizon drops/disconnects. This consistantly happens throughout the day!
1. If I connect to a "local" wireless signal NO dropping.
2. If I tether my Sprint Android, NO dropping.
Only dropping with the Verizon. I MUST have the Verizon dedicated to this work computer to run the VPN and hopefully (very soon) a mandated VOIP with Avaya!Called Verizon- they sent me a new USB thinking that might fix it. But same thing. They are showing signal strength 4G. Nothing on their side.

Global Static NAT Deny IP spoof from (61.X.X.X) to 201.X.X.X on interface Outside
Traffic dies at the firewall stating that the traffic is spoofed from the Global address (61.) to the static (201.) address. Both bound to the outside interface. When I create a static NAT on the firewall there is no problem; however when I'm patting against the firewall to the public IP I get the denies.
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?
