Cisco Firewall :: 5510 - Static NAT Required But Outside NAT Pool Already Exhausted
Mar 10, 2012
I got a project where I have to provide NATTED addresses to cutomers for the internal servers and I found out that the outside address range /27 already in use. We are using 5510 with ver 8.1. We cant use PAT here.
I got a project where I have to provide NATTED addresses to customers for the internal servers and I found out that the outside address range /27 already in use. We are using 5510 with ver 8.1. We cant use PAT here. Any other option to accomplish this task.
I've setup VLANs for voice traffic for each floor of our building with a class C. I'm currently having an issue where the 3rd floor can no longer get an IP on their Cisco phone.
Per the debug, I get an ASSIGNMENT_FAILURE DHCPD: due to: POOL EXHAUSTED.
A 'sh ip dhcp pool' reveals 145 leased addresses on that subnet, which I confirmed by running a 'sh ip dhcp binding' command. The 'ip dhcp excluded-address' command is only configured for 20 addresses, so even with that I should have plenty available IP's in the pool.
I'd like to create dhcp server pool on ASA 5510. I was wondering how big is the DHCP scope that Cisco ASA 5510 can support? Are there any ASA models which can support up to subnet mask 22 for DHCP scope?
I am quite new to firewall, in my company one asa 5510 firewall is there.I configured inside, outside, dns, dhcp and nating.I need to config bandwidth limit (1Mbps) for inside port and I restruct like facebook, youtube and pornsites..And I heard that some subscription is required, really is it required?
I have existing Sonic FW in my company we are moving from sonic FW to ASA 5510 Security plus lice. I have two ISP currently connected to sonic Firewall I am planning to implement Dual ISP configuration on ASA5510.
I'm following a tutorial that 'dumbs down' the modem and lets me use the router for everything.
It asks me to set up a static LAN IP (10.x.x.x range) and edit the DHCP pool of the router. When I'm logged in to the routers admin, it doesn't seem I'm able to do any of this.
Earlier in the tutorial it also asked me to set up a static IP for the router, which I did I suppose.
I've added a screenshot of the admin panel, in case that's relevant.
One of our customers has asked us to Nat from the LAN to the Voice LAN based on destination IP address in order to access a public phone server through a vendor managed voice router..
Internet for everything else | | Inside ------------------------> ASA 5510 -----------------> Voice router ------> outside to public phone server only 10.10.1.0/20 10.10.1.7/320 172.16.20.1/24 Voice-------------------------> 172.16.20.0/24 172.16.20.254/24
Here the ASA5510 has an interface in both networks and the inside network can ping the voice network through the firewall by using non at acls. The phone server can only talk to the 172.16.20.0/24 network. So I need to nat the 10.10.1.0/20 network to the Voice interface on the ASA 172.16.20.254/24.
So I think I need the following static but I get the error below:
static (Inside,Voice) interface 10.10.0.0 net mask 255.255.240.0 WARNING: All traffic destined to the IP address of the Voice interface is being redirected. WARNING: Users will not be able to access any service enabled on the Voice interface. ERROR: Invalid net mask with interface option
have a question. I have a ASA5510 with IOS version 8.2 . I have my firewall and behind it also have a mail server eg 192.168.1.x. When i send email from inside network it doesn't show as if it's coming grom the out side nated public IP of my server but IP of firewall. What am i missing my example nat statements are . Nat-control is disabled.
I have an issue, of two parts. The first part I believe I have figured out, just the second part I am unsure of. I have an ASA 5510, currently, there is a mailserver that is static NAT'ed to one of my ISP routed IPs (not the IP of my main Dynamic PAT/Outside interface). I need to convert this over to PAT for ports 25,80,443, etc (standard ports). I know I need to remove the static NAT statement and add in the PAT statements, but I need traffic from that machine to continue to go out the IP assigned to it by the static NAT. E.G.
1.1.1.1 <- main public IP on outside interface, everything gets internet through this IP 1.1.1.2 <-> 10.10.10.10 static NAT to mailserver, secured with ACLs
I need to enable the mailserver to continue to appear to the world as living on 1.1.1.2, due to MX records and rDNS settings, etc...
The terminology for this setup escapes me at the moment.
I've got an ASA 5510 that has been working like a charm for some time now. Until now we've not had to nat any resources to the outside. I created network objects for an internal host and an external host. The internal host has to respond to requests on tcp/2001.
The internal host has no problem accessing the internet, but when I attempt to access the internal host from the outside, I get the following:
I got the charge of a ASA 5510 running with 8.3(1) version.Found that this is simple config with Patting for inside host and couple of Static Nat for web servers and FTP server as well.
There is lots of other configuration being done,I assume for the purpose of just R&D by the previous administrator.I need to understand if the following Nat statements holding any relevance?
Where we are running Only NETWORK_OBJ_192.168.0.0/23 subnet at inside and there is no other subnet defined in rest of the statements.i.e 10.0.0.0/27 and 192.168.1.128/27 doesn't exist at all.
This problem applies (in my case) to our ASA5510. The issue here is that the http service on the ASA is runnnig off of the standard port 80. Login to the firewall and run the following.no http server enable http server enable 8080,Now you should be able to add a NAT/PAT on port 443 to another server of your liking. Just remember when you attempt to use ASDM to manage the ASA in the future to specify the new port 8080.
At the moment if I try and access data from VLAN 1 to VLAN 4 it gets to the destination ok going through the static route and over the vInterOffice connection but the problem is VLAN 4 returning the traffic. This fails because there is no static route back to VLAN 1. If I create a static route from Office 2 to VLAN 1 then it will route all my data traffic over it as well.
I am trying to set up my ASA5510 the fail over of ISP when it can't ping three different IP. I create three different tracking to three different IP using sla monitor & track rtr. But when I do
the last route will replace the previous two and only the last route command takes effect.Is there anyway I can set up the fail over to ISP2 only when it can't ping three different IP from ISP1?
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.
can i have 2 pools each with diifferent subnet [code] i wanna put restricution on remote vpn users having address from pool-2,and just give them access to 172.16.10.0/24,is it possible on the asa 5510?
My VPN Cisco client connects to the ASA 5510 and everything looks good but when i try send traffic(RDP) severs connects and the logs shows a sync timeout. [code]
Is the following sysntax correct in removing a remote access vpn address pool and inserting a new one on an ASA5510?
(config)# NO ip local pool BWCVPN 192.168.200.1-192.168.200.128 (config)# ip local pool BWCVPN 192.168.300.1-192.168.300.128 (confif)# tunnel-group BWCVPN ciscovpn general-attributes (config-general)# address-pool BWCVPN
I am having touble with a NAT concept. What I have is a 3rd party software VPN product that basically tunnels encapsulated traffic to/from a server sitting inside the network. Right now this traffic utiluizes a physical interface on the ASA5510, but I need the interface for another project.
We have 2 sites with 2 internet connections at each site. All are SRP527w routers. 1 is for internet and 1 is for a site to site VPN as,Currently we are using Static Routes on the PC's so they can access each server no matter what site they are at. I have looked at using the Static Routes section on the SRP's but cannot get it to work.
I had an WRVS4400 (but didn't use the wireless), it it died. I'm replacing with an RVS4000. I have all the settings from the prior router, but my question has to do with the DSL modem in use in conjunction with the router, because (in my absence) my wife had a conversation with SBC, trying to use the hook to the modem directly and ended up altering settings on the modem that may affect the RVS4000 when I go to install it upon its receipt from Amazon tomorrow.
We have a business that uses a third party software vendor's website; their servers access our data on our server behind the router. So we use a static IP address, and port forwarding. No problem there. But I could have sworn that, with the WRVS4400 we used to have the modem configured as bridged; as of this morning, the modem shows PPPoE, and my wife can't recall what SBC had her do in that regard!
So, for the situation I've described, should I put the modem into bridge mode (and porting it into the RVS4000). Like I said, we have a static WAN IP address, and a range of more static IP addresses.
I am using a range of IPs from my inside LAN for my IPSec VPN clients. For example my inside network is 172.16.1.0/24 and I have a pool setup like this: ip local pool vpnpool 172.16.1.200-172.16.1.210 mask 255.255.255.0.
Before the upgrade to 8.4 it was working and now it isn't. Clients can connect and pickup and IP but can't cominuicate with the inside LAN. I think I have to do manual NAT to nonat this range. So I want to try the following:
object network obj-vpnpool range 172.16.1.200 172.16.1.210 nat (inside,outside) 1 source static any any destination static obj-vpnpool obj-vpnpool
However there are two things preventing me from doing this:
1) When I try to create obj-vpnpool I get an error stating that this object overlaps with local pool 2) Even if I create the obj-vpnpool with a non-overlapping range, when in the VPN config I don't have an option for selecting obj-vpnpool.
I’m using a cisco 5510 ASA at the head office and all the branches (32) connect to the head office via cisco VPN client(Remote access VPN), as per the configuration branches used to get ip addresses from the VPN pool randomly. Now, my requirement is I need that each branch should get the same ip address every time when the VPN is established. Is this feasible?
I want to configure multiple DHCP configuration on ASA 5505. I tried to create sub interface for different IP Pool but it was not configure on ASA 5505. is it possible to create subinterface on ASA 5505?
ASA 5505 IOS version: 8.3(1) License: Security Plus
I have one firewall need to be configured in transparent mode. I have inside and outside router. What is the configuration of transparent firewall ASA8.2. I didn't find the configuration on Cisco site.
I'm trying to figure out how to get two 5510 ASA's to establish a Site-to-Site VPN.The version with two static IP's is working perfectly and stable but I haven't figured out how to get a VPN running between a static and a dynamic IP
My dynamic ASA is trying to use a Cradle point 4G connection to a head end ASA-5510. The remote end with the Cradle point 4G is not even initiating the tunnel! I need another set of eyes. it was initiating the tunnel last week but not completing the connection. Now its not doing anything. i am going backwards. Below is my remote ASA config.
ASA5510(config)# sh run : Saved ASA Version 8.2(2) host name ASA5510 enable password 8Ry2YjIyt7RRXU24 encrypted password 2KFQnbNIdI.2KYOU encrypted names [code]...
I have a laptop directly attached to the inside interface. The PC and ASA can ping each other. The test interface is the one I am trying to use. Does my default route need to point to 192.168.0.1? Or is the remote peer correct? I thought the remote peer was correct? The 4G modem is like a pass-thru device. If I connect my laptop to it I can get out to the internet.
I have an internal application which requires operators to have a static IP address. I'm looking for a way to do this for our VPN users. At the moment they are given a random DHCP address from a pool. Is there an easy way to get a static address assigned to VPN users on a Cisco ASA5510 any connect VPN?
I got remote offices connected to our DataCenter some via MPLS and some via VPN terminated on Cisco ASA 5510. I am running OSPF on LAN and BGP for MPLS sites. To have reachability to VPN remote offices I added 'redistribute static in OSPF' and to have rechability to sites connected via metro link i added 'redistribute connected'
