I'm having some trouble configuring 2 cisco routers (877) with ipsec vpn tunnel.The 2 of them are linked to the internet with dynamic adsl's - their ip-addresses changes all the time.when the configuration is based on ip addresses it's working ok, but when I'm trying to use host name with the DDNS feature, it's not coming up, I get a lot of errors...
I've searched google and various posts regarding that issue.It's seems like it's possible to do a dynamic-ip to dynamic-ip ipsec tunnel, but I found zero manuals and configuration.I've added the template that I'm using to configure the tunnel with ip addresses.
I am looking for an option to do the following. [code] Cisco 6509 with SUP2 with MSFC2 full mem
I would like the cleanest most stable option to allow this to work and still be secure with authentication. I know on the home side, I can just specify the remote ip and add a password. Not sure what can be done on the DC side to allow this to work properly.
I need to create a VPN tunnel between two offices of the same company. I bought two Zyxel P-661HW-D to create the secure VPN tunnel but the problem is that the two offices has a ADSL connection with dynamic IP. Is possible, with this router, to use a DDNS service to create the VPN tunnel or it' s required to have static IP ?

its possible to have same dynamic translation within 2 different networks like:
interface gig 0/1
1.1.1.1 255.255.255.0 (LAN Connection w/ DHCP enabled)
inteface gig 0/2
2.2.2.1 255.255.255.0 (Wireless Connection w/ DHCP enabled)
Actually, the scenario was 1.1.1.1 is my LAN connection and 2.2.2.1 are my Wireless connection.
I have devices on Inside interface of ASA that need to get to Internet to get ntp. Hence I want to set up dynamic pat (interface overload) which 8.3 style would be
-object network obj_NTP-DEV
-host 192.168.1.250
-nat (INSIDE,INTERNET) dynamic interface
But I need to limit nat to only Internet destined traffic on ntp port not all ports for traffic from 192.168.1.250.I'm not using this nat set up to control outbound access - I also have incoming RA VPN tunnels to the box and traffic from these sources need to be able to get to 192.168.1.250 and the above simple set up would break that access as all traffic involving 192.168.1.250 would get nat'd
Reading the doco I've sent myself round in a loops trying to figure how you are meant to do such a " Dynamic Policy NAT (overload)" call it what you will config in 8.3
have 2 inside networks:
object network INSIDE_10.6
subnet 10.6.0.0 255.255.0.0
object network INSIDE_192.168
subnet 192.168.0.0 255.255.255.0
I grouped these 2 into 1 object-group:
object-group network INSIDE
network-object object INSIDE_10.6
network-object object INSIDE_192.168
Public IP address used for PAT:
object network PAT
host 152.x.x.x
I used the following statement to create Dynamic PAT to public IP address:
object network INSIDE_10.6
nat (any,any) dynamic PAT
object network INSIDE_192.168
nat (any,any) dynamic PAT
Is that correct? Also I'm using one public address to PAT both inside networks. Is there any dvantage of using 2 different ones, so each inside network would be PAT to its own address?
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?
View 3 Replies View Related in ASA 8.4, I need to use to static nat an internal IP with a public IP and use the same public IP to dynamic nat another internal IP:
-nat (inside,outside) source static IP1_PRIVATE IP_PUBLIC
-nat (inside,outside) source dynamic IP2_PRIVATE IP_PUBLIC
All outgoing connection from IP1_PRIVATE and IP2_PRIVATE should be natted to IP_PUBLIC and all incoming connection to IP_PUBLIC should be forwarded to IP1_PRIVATE: is it correct ?
I have a site with an ASA5505 and 2 isp connections but the catch is the 2 isp's are giving me a dynamic IP so I am unable to use this [URL]

I'm talking about the latest versions.
we are running 8.4(2) on the asa with the below configuration we basically have a static for .7 on .25 and a nat for .7 for port direction with manual nat that takes precedense over auto nat within the object group am I correct that I dontneed the dynamic statement and that its redundant?
-object network obj-10.X.0.25-02host 10.X.0.25
-object network obj-10.X.0.25nat (any,INSIDE) static X.X.X.7 dns
-object network obj-10.X.0.25-01nat (INSIDE,OUTSIDE) static X.X.X.7 service tcp smtp smtp
-object network obj-10.X.0.25-02nat (INSIDE,OUTSIDE) dynamic X.X.X.7
To configure a dynamic NAT, PAT, or identity NAT rule, I need to perform the following steps:
Step 1 From the Configuration > Firewall > NAT Rules pane, choose Add > Add Dynamic NAT Rule.
The Add Dynamic NAT Rule dialog box appears. However, when I click on Add I don't get the option to Add Dynamic Nat Rule. To see the options I get please see attachment.

I have ASA 5510 and public FTP server from my local network to external IP address, with static nat translation. All works, but I need request to ftp come from internal ASA interface (need use gateway different ASA). How configured ASA for forwarding request?

I have a ASA5510 with 2 internal interfaces (inside1 and inside2 same security level) configured with OSPF for dynamic routing with 2 routers to corporate subnets. I have a server in a private subnet that needs to be accessed from Internet. So static pat is used in ASA with the command
static (inside1, outside) tcp interface www 192.168.1.1 www netmask 255.255.255.255
As OSPF is in use, the subnet 192.168.1.0/24 may be reachable from interface inside2. When I tried to configure the static command for inside2,
static (inside2, outside) tcp interface www 192.168.1.1 www netmask 255.255.255.255.the error message came out "WARNING: mapped-address conflict with existing static...". Is this just a warning, or this is not possible in ASA.
I've been tracking a conversation on my firewall. I have an inside device that is trying to communicate to a server outside to send data. The conversation is suppose to be all 443. I see that there is a TCP connection made and a dynamic NAT that translates my inside device to the public IP, and appears to change the port to 65415. The problem I'm having is that the conversation ends with reset-O, and I'm wondering if that port has something to do with it, or if it's just that their server is resetting the connection because of an issue they are having? The vendor says no firewall rules are needed for this device to communicate with their server.
View 4 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.
View 7 Replies View RelatedI have an asa5520 runing 9.0 that I want to setup for simple NAT, i,e 4.3.2.1/30 on the outside 192.168.1.1/24 on the inside with dynamic NAT outbound. The new IOS has thrown me for a loop.. I have everything working except the NAT. Any SDM screen shot of the Dynamic NAT entry? even if the IP's are different, I can figure it out...
Also, is there a way to make the unused ethernet interfaces gig0/2 and 0/3 into switch ports on the internal net? (or VLAN like you could do on the 5505)?
I need to allow traffic between webserver in dmz and mssql (Microsoft SQL Server 2008).MSSQL use dynamic port (now it is 63796) and this cannot be changed.
Basically, I can allow such traffic using next configuration:access-list dmz extended permit tcp host 1.2.3.4 host 5.6.7.8 eq 1433access-list dmz extended permit udp host 1.2.3.4 host 5.6.7.8 eq 1434 access-list dmz extended permit tcp host 1.2.3.4 host 5.6.7.8 eq 63796
But, I would like to add mssql inspection and I did the next:
class-map class_sqlnetmatch port tcp eq 1433policy-map global_policyclass inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect ip-options inspect netbios inspect rsh inspect rtsp inspect skinny inspect esmtp inspect sqlnet inspect sunrpc inspect tftp inspect sip inspect xdmcp class class_sqlnet inspect sqlnet service-policy global_policy global

this is ASA5520 associate with 8.4(1). very simple scenario , three ports: inside . outside . DMZ my problem is how to use network object NAT to perform Regular Dynamic PAT and Identity NAT.
for example, this is my configuration
**** first i configured Regular Dynamic PAT****
object network myinside
subnet 10.200.11.0 255.255.255.0
nat (inside,outside) dynamic interface
**** then , i met problem when i want to make identity NAT between inside and DMZ****
**** if i add below CLI , the first nat line will be replaced ****
**** SO IF I ADD THIS****

View 4 Replies View RelatedFirewall ASA5510. I'm planning to get one of ASA5510 for our office in order to secure our network properly, however we have quite specific routing configuration to allow us failover to the remote location (data center) in case of any disaster with our server. I'd like to find out if I can just install firewall between our ISP Ruter and internet and allow traffic to/from Data Centre. In this situation will I have to change routing configuration on Company Router or do I have to do anything with our Company Router

View 1 Replies View RelatedI have our main site using a Cisco 5510 running 8.4.2 code and a remote site using a Cisco 5505 running 8.4.2 code. The main site has a T1 and the remote site is using a DSL connection. About every other day I have to reset the connection at the remote site. The process that I have found that works is to remove the nat statement, clear the cry ips sa and then add back the nat statement. The connection usually comes back up and a few minutes. I am trying to see what is causing this to drop.

Obviously our crypto map's don't match, i have it restricted to specific ports on my end and he had it wide open on his end, but said he is not sure how to restrict it down to specific ports. My question is why would I be able to bring the tunnel up on my end if the crypto map's don't match and he can't bring it up?
