i'm running a 5510 asa and the vpn has been working great for a while. We recently change our network provider so i had to change the public ip, and dns on the firewall... now i can still connect via the vpn and browse accross my mpls to other sites, but cant really access anything on the native lan that the firewall resides on?

View 3 Replies View RelatedI have a Cisco ASA 5510 I am using ASDM 6.1
I have a LAN and a DMZ and an internet connection. I am using one of the internet connection IPs to host a HTTP service on a server in my DMZ. (its the same interface as my internet connenction but a different IP to the one used for internet connectivity)
so say my LAN is 192.168.1.x
and my DMZ is 172.168.1.x
I can access DMZ from Lan and vice versa. when i try to access the public IP (or URL) from a pc in my LAN i get nothing.
I have enabled DNS rewrite (doctoring) but it is still not working. the HTTP service is available from other sites.
Is PVID the same thing as "native vlan"? Can the native VLAN be changed on a SA520? Currently I believe it to be 1, I'd like to change the native VLAN to 10.
I have a scenario where I have a prexisting production LAN of 192.168.1.0/24 . It's a small organization (a church), but they purchased 3 Aironet 1130ag units. They want to have a "private" WLAN that is part of 192.168.1.0/24 , and a guest WLAN of a different subnet (I chose 192.168.20.0/24) . The two should never meet. There will likely never be a guest computer connected via ethernet. Guest computers would always have to connect wirelessly.
I left VLAN 1 on the SA520 192.168.75.0/24 subnet as default.I created a VLAN 10 , 192.168.1.0/24 subnet, and I created a VLAN 20, 192.168.20.0/24 subnet.Ports 1-3 of the SA520 are members of VLAN 1, 10, and 20 (cannot remove membership of VLAN1, which is pretty annoying).
Both are secured by WPA, and when I connect, the proper DHCP subnet passes from the firewall through to the wireless client, for each respective SSID.Ultimately, I'd like the SBS 2003 server to handle DHCP for VLAN 10, and have the SA520 handle DHCP for VLAN 20, but i'll take what I can get.
The original production LAN is connected via an unmanged switch.I'd like to trunk the unmanaged switch to Port 4 on the SA520. However, since the PVID (native vlan?) of SA520 is 1, and I cannot make Port 4 on the SA520 ony a member of VLAN 10, then anything traffic coming from the unanaged switch will automatically be tagged with VLAN1, correct? Thus causing the already existing production network to start receiving DHCP from the firewall in the 192.168.75.0/24 range.
Will I break anything if I create a second IP address on the physical external interface of our ASA 5510? I want to point it nowhere internally but want an active interface that can be vulnerability scanned but won't lead anywhere internally.

when i try to access owa(public ip ) from dmz it is not allowing , From what rules i need to set to get work ASA 5510 8.2
I need to connect from an inside host to a host located in the DMZ zone for DNS queries. The host in the DMZ zone has a static NAT to the outside. The point now is that I would like to connect from inside to the NATed outside address, means to the public Internet address.
Inside host: 10.0.0.1 -> PAT for 10.0.0.0/8 to 20.0.0.254 (Outside Interface)
DMZ host: 192.168.1.1 -> NAT to outside to 20.0.0.1
The traffic should be 10.0.0.1 udp>1024 to 20.0.0.1 udp=53. The source IP address on the outside interface now is 20.0.0.254 (according to the PAT), the destination IP address 20.0.0.1. The DNS reply from 20.0.0.1 should go back now to 20.0.0.254 and then to the inside host 10.0.0.1.
I know that on the PIX it was not possible, to have outgoing traffic on the outside interface which immediately enters again the same interface. Can I realize this scenario with the ASA 8.4(3) release now?
We need to deploy a Cisco ASA 5510 behind the Internet facing router for Remote Access VPN (RAVPN). We bought the block of 16 IPs (in a different subnet) which is routed through the main router (69.x.x.x)and configured the outside interface of ASA with a public IP 64.x.x.x and subnet mask 255.255.255.240. Below is the network structure.
But, we can't access the ASA by it's public IP.
DSL Modem → RV082 router → Switch → LAN

Cisco ASA 5510
(outside: 64.x.x.x, inside: 192.168.0.172)
Our ASA 5510 was configured with a public interface, a DMZ interface, and a private interface. I have a remote access VPN using AnyConnect client and LDAP authentication for Active Directory. We are changing ISP (groan!), which means all new public IP addresses. The new circuit is installed, so I have a second public interface (same security level as the first public interface, wholly different IP address range) enabled on the ASA. I hope to transition whatever I can, which means get the VPN access through either public interface. Can I just enable client access on the second public interface at the Anyconnect Connection Profiles tab in ASDM? That seems too simple. Can they share the one address pool?

View 3 Replies View RelatedWe have ASA 5550, I have a portal server in the dmz which is natted statically to a public ip address for port 443. The application works fine from outside world. The server is also nated with a dynamic nat from inside to dmz and when I hit on the dmz ip from my inside it works fine.
The requirement for us is that the users sitting behind the inside (i.e. LAN) should access the server on the public ip address and not thru the dmz.

View 3 Replies View RelatedOur HQ office has an ASA 5510 with full access to internal and external IP's. We have a small group of remote users that are working from a shared office suite and they only have Internet access by way of internal default gateway. Using a VPN client is not desirable due to many other devices requiring access to HQ. Is there a way to create a site-to-site VPN from this remote office space back to HQ (ASA 5510) if they have no access to the public IP address on their end?
View 2 Replies View RelatedI was talking to a friend today and he told me that a router changes the IP address you're given to by the ISP? So I checked with whatismyip.org and let's say with the router, it showed, 29.28.29.450, Then I took the router out and just used the modem and it showed as 29.28.29.449 If I were to use a different router, would it end with 450 again? Or an entirely different number, because the router is of a different brand? I'm assuming having a router is good for protection from malware, trojans and what not?

View 1 Replies View RelatedI 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.

Everything was working fine and I was poking around in the router settings and clicked the Clone Mac Address button to see what it did and hit Apply.
Now the internet isn't working (on the neighbor's internet) and I can't even get back on the router (192.168.1.1) I reset the router but it still isn't working.
I have an ASUS Wireless Router RT-N66R.
Edit: I got back on the router but now my wireless MAC address is the same as the LAN MAC address. I think this is what the cloning did. Is there any way to find my old MAC address?
The section is titled Special Requirement from ISP so I think I may need to use a certain MAC address but I don't remember what the old one was.
I have a 2811 Router (config below) with VPN configured. I can connect through the VPN and access devices on the native VLAN but I can't access the 10.77.5.0 (VLAN 5) network (I don't care to access the 10.77.10.0 - VLAN 10 network). This issue has been plagueing me for quite a while. I believe it's a NAT or ACL issue. VPN client IP pool is 192.168.77.1 - 192.168.77.10. [code]

My ASA 5510 is configured with a single PUBLICIP1 on the outside interface. All internal hosts 192.168.0.x are behind the ASA firewall and NATed to PUBLICIP1 including a few site-to-site VPN tunnels. This is also true for DMZ. Now, I would like to add a second PUBLICIP2 to the ASA and map it to one internal host ONLY - For eg: 192.168.0.25. How can I do this without effecting the existing setup? Since my entire internal subnet 192.168.0.0/24 is NATed to an existing PUBLICIP1 how can I exclude just one host (192.168.0.25) and bond it to the PUBLICIP2 for all ports.
This is what my current OUTSIDE interface looks like.

View 9 Replies View RelatedI am setting up a site to site IPsec connection with a company, something which I have done many times before without trouble. I use ASDM to configure this as it is quick and painless, usually.
We have a number of other site to site connections currently configured and working fine on this ASA, these are configured with the 'Protected network - Local network' configured with the private IP's of the hosts within our network we want to make available through the seperate tunnels. This includes the configuration setting on our ASA for each connection to 'Exempt ASA side hosts from NAT'.
With this new connection however, the company has asked us to use a public IP for the host we want them to reach through the tunnel. I am not sure why but they demand it. So I added a NAT rule for the inside host, and configured the connection with the public IP under 'Local Network'. When testing to try reach a host on their side, the tunnel does not even attempt to initiate.
I cant see where I am going wrong. I am guessing the 'Exempt ASA side host from NAT' does not require to be set for this, as how else would the ASA know which internal host the public IP relates to.
I have a peculiar situation where I need to assign a public ip to a computer without going through firewall (for testing purpose).
I have the leased line going through a 3750 switch to the ASA 5510(15.240.1.2/30) belonging to vlan 999. ASA has default route going to 15.240.1.1/30(ISP).
I have different public ip range for LAN and WAN My WAN ip is 15.240.1.0/30, LAN ip range is 15.240.2.24/27 nated by ASA..
I want to connect the PC to the switch port belonging vlan 999 and ip address of 15.240.2.26/27.
If yes, what will be the gateway for the computer?
i just got an extra public subnet from our ISP (co hosting center) But I can't figure out how to use them on my ASA.

Default gateway: 87.1.1.193
Subnetmask: 255.255.255.192
Old:
IP-adresses: 200.1.1.34 - 200.1.1.46
