I am using 2 vpn-routers RVS4000, to interconnect 2 hybrid telephone IP-PBX. After configuring the VPN the head offices are not seen in network. The VPN is active in windows.
IP-PBX works correctly in te same LAN. I understand that the problem is that I do not find how to indicate the router to send de UDP packets to the correct IP thought the VPN.
I'm trying to translate my inside network of 192.168.20.0 to my outside ISP address on ASA 5505. The ping from all hosts to 4.2.2.2 works, but it still only let's one address out to translate.My configuration is:
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0
still doesn't work.

I am desperate to make some kind of translation which convert an outside IP Address of our web server to its inside ip address so that requests can be routed internally to the server.
This is what we have: A wireless network with an SSID to serve visitors. We also have an in-house web server which can be accessed internally and externally. We have a ASA 5520 that protects the internal network, including the Web server, and also routes all traffic from the all visitors connected to the public SSID to the outside. The DHCP server for the wireless network for visitors is configured to give the 8.8.8.8 as dns server. The problem with that is that the www.ourwebserver.com is resolved by Google's dns server to the public IP Address of our web server! The traffic then is sent to the outside interface of the ASA 5520. The visitor who wants to access our web server cannot connect!
How can I configure the ASA to route that traffic to our web server with the public ip address to the inside ip address of the web server?
Is it possible to assign public IP address as Router's local IP address (RVL200, RVS4000)?
View 1 Replies View RelatedI just tried replacing a cheap domestic router/switch with an RVS4000 V2 on our work network. This has a WAN connection to a cable modem for internet access via a dynamic IP address.
When I first connected the RVS4000 it got a WAN ip address via DHCP of 192.168.100.11. This is the type of IP address we get when there is an upstream problem with our ISPs cable network, and sure enough we had no internet access. The RVS4000 was set to use DHCP on the WAN interface. So I logged a support call with our ISP but they said there were no problems at their end.
I then swapped the RVS4000 out for the original router. This worked fine and got a WAN DHCP address of 77.xxx.yyy.zzz as it should. Swapped back to the RVS4000 and back to the same problem of getting a 192.168... address.
So, I downloaded the latest firmware from Cisco, which was V2.0.3.2 and flashed the RVS4000.
I then tried again connecting the RVS4000 to the cable modem but this time it would not get any WAN DHCP address at all. On the Status/Gateway page of the web interface it said that the WAN interface was down. However, on the front panel there was a yellow light indicating a live connection on the internet port.
I read somewhere that the security log could be set to display web address vs dns address. How do i adjust this?

View 6 Replies View Related I guess I'll start with the easy stuff, Cisco ASA 5520 ver 8.2, ASDM ver 6.2, IPSec L2L tunnel with overlapping private IPs.
I have about a dozen L2L connections on our 5520 but never had to do one with overlapping IPs. I have two that I have to build and one definitely overlaps our inside locals, and the other is requesting that we NAT our inside locals to a 10.x.x.x.
I've searched the board and found several good posts including document 112049, but I just don't seem to be able to get my head around how to translate one inside address to another. It would seem like is would be as easy as doing an (inside,inside) static NAT, but most everything has the solution as a policy NAT or doing an (inside, outside) but in the less secure address space place the name of an ACL. I have ordered that brick of a book on ASAs from Cisco Press, but need to get something going and I'm not having much luck getting this thing up and running.
Perhaps my basic understanding of NAT rules is wrong. I thought that when using NAT the command speaks to the interfaces and the direction of travel, (inside,outside). I also thought that the IP adresses used must be valid on the interface refferenced, so any refference to "inside" would have to be an address on the "inside interface of the FW and likewise for the "outside" interface. Finally, to be sure I'm not calling a duck a goose my understanding is that the following are correct; "inside local" = my private, "inside global= my peer, "outside local"= their private, "outside global"= their peer.
So if I'm translating say a 192.x.x.x on my inside local and wanted to present them a 10.x.x.x, wouldn't I need an (inside,outside)? And even though I'm translating my private IP into a different private IP, the translated IP must be on the "outside" interface because that is the interface that I want to present the new private IP on?
So for the scenario I suggested at the top where I need to translate my private 192.x.x.x into a 10.x.x.x and present that 10.x.x.x to the other side, I need something like NAT Static (inside,outside) 10.x.x.x 192.x.x.x?
I have just installed and configured a new RVS4000 with VPN (currently running firmware V2.0.0.3), and have enabled the DHCP Server service. I wanted to be able to distribute a search domain in addition to the IP address and DNS Server information (as I have done with other devices that include a DHCP Server), but cannot seem to locate where or how I might do that with the RVS4000.
View 4 Replies View RelatedI 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?
I 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 am trying to get two external addresses to PAT to different ports on the same address in the dmz.
Object NAT is configured as follows:
object network Obj-192.168.1.20-1
nat (dmz,outside) static Obj-External-1 service tcp https https
object network Onj-192.168.1.20-2
nat (dmz,outside) static Obj-External-2 service tcp 2000 https
Obj-192.168.1.20-1 and Obj-192.168.1.20-2 contain the same host address.
The idea being that traffic destined for Obj-External-1 on port 443 will be forwarded to Obj-192.168.1.20-1 on port 443. Traffic for Obj-External-2 on port 443 will be forwarded to Obj-192.168.20-2 on port 2000.
Traffic for the first object, Obj-192.168.1.20-1, works but traffic for the second does not.
I have a handheld device that will be used for inventory outside of our office. It has 3g capabilities. Is there anyway I can permit traffic from this device from the outside world coming into my network? I need to open a couple of ports so it can hit the server. But I have no intention to open these ports up to the entire world. I use an ASA 5520 with a managed router from our provider. I looked around on the Cisco site and the only information I found was for permitting and denying traffic from devices that are within the network.

We've had issues with our Exchange 2010 server (running on ESXi 4.1) since its default gateway was changed to our new ASA 5510. They manifested as frequent Outlook client connection dropouts or as IP address conflicts whenever Exchange was rebooted. The temporary fix was to disable the Exchange server NIC, bounce the ASA and enable the server's NIC again. We saw poor performance from Exchange after a while again, but after some research and testing I realised that disabling proxyarp on the inside interface fixed the problem permanently.
However I've now realised that the client VPN no longer routes properly because proxyarp is disabled on the inside interface, so I still have a problem.

I have an ASA 5510, with Ethernet0 connected to Internet via a T1 line, Ethernet1 connected to LAN1, and Ethernet2 connected to LAN2. LAN1 & LAN2 are independant, but share the Internet connection, via the T1 line. On LAN2, I have another router that connects to the Internet, via a Comcast line. I wish to route some of the traffic on LAN2 (10.38.77.0) to the other Router, on LAN2 (10.38.77.12) (connected to the Comcast line). I have entered the following lines:
route inside2 10.11.0.0 255.255.0.0 10.38.77.12 1
route inside2 10.252.0.0 255.255.0.0 10.38.77.12 1
route inside2 172.22.6.0 255.255.255.0 10.38.77.12 1
I can trace the routes from the ASA 5510 (1st hop is to 10.38.77.12), but not from anything else on LAN2.

I have a triangle of CSB RVS devices, 2 RVS4000, 1 WRVS4400 each router has a gateway to gateway VPN with the other 2, so from any of the 3 sites, you can access the resources on the other 2. It also works well, that if for some reason one of the VPN legs goes down, it routes through the other router. atleast It appears to work that way when tested.
I have 2 laptops that go around, Mine and one at the office. If either of these are off site and connect to any of the routers through the QuickVPN client. they can only see the resources on the router they connect to. How would I be able to connect in to 1 router, and be able to access resources on the other VPN'ed routers?
old laptop (Dell Inspiron 8000) which works on his Linksys BEFSR41 router, but it will not work with my RVS4000 router.

The additional ports on the RVS4000 are black (the green LED lights won't turn on). My desktop works using different RVS4000 ports, but alas, the laptop won't. I have rechecked the router settings, tried disconnecting the cable modem and the router (to reboot), and unplugged the power overnight, but nothing works. I even tried changing the duplex settings from auto to 100 full duplex which didn't work either.
