I need to replace an ASA with an IOS firewall router, and am not sure how to migrate the NAT configuration. Specifically, there is an interface "3rdparty" that has onward connectivity to other private addresses, so our internal addressing is hidden. For some reason there are static NAT rules in different directions across the interface, but at present I cannot see why. Thinking in router terms, all that springs to mind is the inside and outside tags for the interfaces, but also that it might need "overlapping" NAT to be configured.

I want to remove VPN configuration from the router and put VPN Configuration on Cisco ASA 5505.The scheme would be: ASA5505(vpn site-to-site) -> 887 -> INTERNET this for both sites.My problem is that I do not know what ip put on interface Outside of firewall. For example on Site A delete all VPN configuration from 887 and leave only ATM0.1 point-to-point, on intereface Outside of ASA put ip of loopback(of router 887) and as default route 85.34.2.XXX. Right?
We try to migrate two ASA stateful Active / Passive from version 8.0 to 8.4 but many of acl rules and Nat no longer working. We must go through the version 8.2? The release 8.4 changes everything and seems to me not too stable, it'sl best to stay in 8.2 or 8.3 !!!
View 3 Replies View RelatedI need to upgrade the compact flash of my ASA 5510 from 256MB to 512MB. A friend's recommendation was to buy a card reader, copy all of the data from the existing card and paste it to the new compact flash. I have a hard time believing that it's that straight forward.
Any safer, more foolproof way of migrating between flash cards?
I am working on a project to migrate a single Checkpoint firewall over to a single ASA 5510, no VPN, just firewall. The checkpoint firewall has 8 physical interface so the ASA 5510 also support physical 8 interfaces so thiw will be a one-to-one swap. At the moment, I don't have an ASA 5510 to test my theory so I am going to throw it out here. The checkpoint firewall is a SPLAT running on an powerfull IBM Server with 8 CPU dual cores with 32GB of RAM and it has 1200 rules with over 120,000 objects with some of the crazy NATs but it works so we will just leave it at that. There are not that much traffics going across the firewall so there are no need to put in an ASA 5585
I use the cisco conversion tool to do the policy conversion from Checkpoint to Cisco, I get about 1.5 million lines in the configuration. A lot of it has to do with Checkpoint having no concept of interface security level while ASA does. I am sure I can optimize it to cut down the number of lines in the configuration; however, that is not my main concern at the moment. The customer goal is that at the time when cutover from Checkpoint to Cisco ASA, they want everything to be perfect, meaning that it will work like magic.
My question is that can the ASA 5510 handle 1.5 million lines of configuration? Are there any limitations on this? I know there are limitations with FWSM but since I don't have an 5510 to test.

We have backup data center where I am now planning to provide backup internet service ( in the case where there is internet down or power outage at main server room) . I have a pair of Cisco ASA's 5540, one of which I need to move to backup data center ( BDC), Presently I have ADSL router at disaster serve room with static public IP from ISP.
Currently, I am publishing all my internal resources through ASA. Now my questions, if I move Standby ASA to Disaster Server Room. How I can publish the same internal resources through standby ASA and make it standby as active during the down time of main server room

its basic configuration where i have my server on the inside network (172.16.0.7) which i want it to be natted to public ip to (195.44.148.53) .
i tried to add an access-list ingress direction on the outside interface to permit traffic from any to the public ip 195.44.148.53 but still its not working.
i am doind a policy NAT on the folowing scenarion.
acess-list policy_nat extended permit ip host 10.0.0.1 host 192.168.1.1
static (inside,outempresa) 170.66.53.1 access-list policy_nat
I understand that when host A 10.0.0.1 wants to connect to host B192.168.1.1 its going to be translated to 170.66.53.1 when host 192.168.1.1 wants to connect to10.0.0.1 the same entry will change the destination when the packet hits the asa from 170.66.53.1 to 10.0.0.1, is that correct ?
I just replaced a PIX 501 with a new ASA5505. I had a very weird problem and would like to know what caused it incase I run into it again. The setup is a DSL connection, with an old-ish speedstream DSL modem. Static IP, no PPPoE. I had a PIX 501, then two servers with static NAT entries on secondary WAN IPs. Everything was working fine on the PIX, I just duplicated the config over to the ASA. I swapped out the PIX for the ASA, and rebooted the DSL modem to clear out it's cache. After installation, NAT was working fine for the the global pool, but the systems with static NAT could not get online. I tried lots of different things to fix them, and they never worked. Finally I rememberd running into an issue like this a long time ago, in that the static NAT IP's wouldn't work without giving them a bump-start on the network. So I assigned the ASA each of my WAN IPs, one at a time, and tested them all. After that I went back to the original WAN IP, configured the static NATs, and they fired right up. why did my static NAT entries not work until I first assigned them to the ASA, then swapped back? I did reset the DSL modem when I swapped the firewalls, so I don't believe it was an ARP issue (unless it was an ARP issue at the far end?) I would like to know if there is something I can do differently with the devices or with the config to not have this issue again in the future.

I have a firewall which is conntect to a Cisco 870 router.
The router only allows one ip address to ssh into and it which is 7.7.7.7 but the interface which is connected to the router is on the firewall is a 2.2.2.2 and the router interface is a 2.2.2.1.
I can ping the router from the inside of my firewall, but I can't ssh into it at is has a access list which will only allow ssh from the ip address 7.7.7.7.
Would it be possible to do a static NAT which can translate the 2.2.2.2 to a 7.7.7.7 when I ssh into the router when coming from the inside?

We have a Cisco ASA 8.3 and we're trying to configure NAT with multiple types of NAT.
We have a static NAT to an inside host from 1.1.1.2.
Internet Interface is on 1.1.1.3.
Users get NAT (PAT) on 1.1.1.4
VPN Subnet "No NAT" exclusion is from our LAN to various other locations.
Here are the relevent extracts from our configuration:
object network Server
host 172.19.0.80
nat (inside,outside) static 1.1.1.2
object network Inside_LAN
[Code]...
When the VPN exlusion ACL is applied to the configuration, PAT users have no connectivity to the Internet via TCP though UDP and ICMP traffic still passes. The VPN is operational. With the VPN NAT configuration removed, as expected the VPN fails, but users have connectivity to the Internet.
We have network topology:
Inside Network (172.168.1.0/27) --- ASA5510----- Outside network (192.168.10.0/24)
ASA5510 have: Inside interface: 172.168.1.30/27; outside interface: 192.168.10.254
And we config:
# object network obj_inside
# subnet 172.168.1.0 255.255.255.224
# nat (inside,outside) dynamic interface
[code]...
So, we í in from outside, we can't access web at 192.168.10.10?
Is there anyway to migrate off of WCS to Prime NCS? We have a fully built WCS system with maps and all configs and was wondering if there was a way to restore to NCS.

View 4 Replies View RelatedCurrently a customer has all theLAN devices using a router as the Default Gateway. The router also do the Dynamic NAT to the internet access and has NAT/PAT rules to publish some services like HTTP and FTP. As I know the router will permit all the incoming traffic in all its interfaces without restrictions at less there is an ACLs that restrict the incoming traffic on an specific interface.Now the customer has bought a brand new ASA and wants to use it as the default gateway for the entiery LAN. This means, the ASA will have the internet connection and will be the responsible for the NAT/PAT process.
I have configured the NAT/PAT rules already following the current router configuration, but I need to know if I have to configure ACLs allowing the incoming traffic on th Outside interface for the services I NATed.
I have a Cisco ASA5505 running 8.2(1) and I am using ASDM to manage the firewall. I have a Linux VPN server on the inside with and IP address of YYY.YYY.YYY.39 with a static NAT to the outside with an address of XXX.XXX.XXX.171 . I have a site to site VPN tunnel which terminates on the outside of the ASA on the outside interface XXX.XXX.XXX.190 .Traffic from the YYY.YYY.YYY.0/24 network can't transverse the site to site VPN as there is a conflict of IP address's on the far side so it is natted via a dynamic policy to host address ZZZ.ZZZ.ZZZ.100, Users remote into the inside(YYY.YYY.YYY.0/24) for support via the Linux VPN server (.39) and then need to communicate down the site to site VPN. The problem is that the static NAT for the incomming connections takes preference and bypasses the site to site VPN tunnel for outbound traffic. I tried to create a policy Static nat but it tries to modify the static nat that handels the incomming traffic to the Linux server.

Recently we migrated our network to ASA 5515, since we had configured nat pool overload on our existing router the users are able to translated their ip's outside. Right now my issue was when I use the existing NAT configured to our router into firewall, it seems that the translation was not successful actually I used Dynamic NAT. When I use the Dynamic PAT(Hide) all users are able to translated to the said public IP's. I know that PAT is Port address translation but when I use static nat for specific server. The Static NAT was not able to translated. Any conflict whit PAT to Static NAT?

I have a 5505 for a small business that has one web server. The web server has a static NAT entry to an IP address and not an interface. There is an access rule allowing any HTTP traffic to the outside IP of the web server. From the web server I can't access the Internet.
All other computers on the network can access the Internet using a dynamic nat rule that uses the outside interface. The web server is accessible from a computer behind the firewall.
If I delete the static NAT entry for the web server I can get on the Internet.
I have turned debugging on and see that an outbound connection is built and then 30 seconds later the connection is torn down with the bytes 0 SYN Timeout message.
