I am able to connect to my Cisco ISR 891 via VPN with the Cisco VPN Client 5.0.07.0440, but once connected I cannot access hosts on the inside. If I ping a host on the inside by name, nothing resolves. If I ping by IP, I get a reply from the public IP of the router. [code]

DNS resolution works and I can surf the web without fail. But if I try to ping any external hosts (I can ping inside interface of ASA fine) from the LAN I get timeouts. I can ping anything from the ASA without fail.

I am able to reach VPN clients (Anyconnect) only from hosts directly connected to the ASA's inside interface subnet. However, hosts on other internal subnets (177.1.10.0 & 177.1.11.0) are unable to connect to clients on VPN. The ASA is running ver 8.4. [code]

Internal interface: 172.16.1.1
External interface: 172.16.2.1
Routing to 192.168.0.0 via internal host.I've got some static NATs, e.g:
object network obj-192.168.0.1
nat (inside,outside) static obj-172.16.2.1
object network obj-192.168.0.3
nat (inside,outside) static obj-172.16.2.2
I also want in internal NAT, but only for certain external hosts, so when they connect to any of the above, their source address is changed. I've attempted the following so an external host (172.16.2.254), has it's source changed to 172.16.1.100.
nat (outside,inside) source static obj-172.16.2.254 obj-172.16.1.100
But it's source remains unchanged.What am I missing?
I'm just new with ASA. I'm just self-studying on it. I was tasked to have an ACL that will allow inside hosts to access a specific network. Is there a way on how to know all the inside hosts on the behind ASA so that I can do a "object-group network" on those inside hosts which I think it will look neat.

Does the Insides Hosts :10 line mean that only 10 devices can be connected to the firewall at one time? I would like to connect an AP to one of the PoE ports and have possibly more than 10 connected. Is this possible with this ASA5505?
One of our company guys always complaining that few inside PC's are frequently loosing internet and reconnecting after some times.The Connectivity is as mentioned below:
Inside: Switch -> Router -> ASA -> Router -> Modem ->Internet ------------VPN-------------------------
I want to upgrade "inside hosts" from 10 to unlimited on a ASA5505-BUN-K9, Do I have to buy Security Plus license ( L-ASA5505-SEC-PL =) ) before activating ASA5505-SW-10-UL ?
View 3 Replies View RelatedI am using ASA 5505 firewall with base-license. I connected my firewall to one cisco 3750 switch where i created 5 vlans. I done NATing for all vlans and they able to get internet and working fine. They able to browse all internet sites like gmail and yahoo mail.
All internal users are configured to use Outlook for their webmail. Here the problem is with outlook they are unable to send and receive the mails.
If they directly connected their system using public ip( Directly from ISP) they able to send and receive mails from outlook.
This is an issue I'm currently exploring with TAC, but I'd like a quick reality check. We have a pair of ASA 5510s in Active/Standby stateful failover mode. In some tests failing over from the active to the standby system breaks SSH connections from hosts on our Inside to hosts on our DMZs.
A specific example is our backup server on Inside which is connecting to our mail server in the DMZ2, and running ssh/rsync/scp for the backups. A running backup job fails with network timeout errors when I trigger the failover. Also, sometimes the mail server loses or hangs on its connection to our LDAP server in DMZ1, although sometimes this connection is fine (DMZ2 is more "inside" than DMZ1, and I assume the LDAP look ups are many short connections, vs the rsync backup being one long connection).
TAC has suggested that open SSH sesions will always fail when the ASAs failover. I believe this is true for management connections to the ASA, but I don't see why it should be the case for an SSH session through the ASA to a server in the DMZ. TAC has suggested that I open some connections to servers in the DMZ and test what happens, and I can do so this Wednesday morning during a maintenance window.But, in general, is this true? That is, given an SSH session from a workstation to a server, should a failover break it? If so, why?
The setup is:
MyWorkStation-INSIDE -> CoreSwitch (vlan 10) -> [ ASA-INSIDE - - (ASA-internal-connection) - - ASA-DMZ ] -> CoreSwitch (vlan 3) -> TargetServer
That is, all our inside VLANs are routed by our core L2/3 switch to a VLAN that connects to the Primary and Secondary ASA's INSIDE ports. There are also seperate VLANS on the core for the ASA's DMZ1 and DMZ2 connections, which go to both ASAs and to any servers in these zones.
The description of the ASA Stateful failover [URL]says: "The state information passed to the standby unit includes these:
· The NAT translation table
· The TCP connection states
· The UDP connection states
· The ARP table
· The Layer 2 bridge table (when it runs in the transparent firewall mode)
· The HTTP connection states (if HTTP replication is enabled)
· The ISAKMP and IPSec SA table
· The GTP PDP connection database
[code]....
I'm not quite sure what the ISAKMP and IPSec SA tables do, but shouldn't an SSH connection through the ASA be just a TCP connection? "For us, SSH from Inside to hosts in the DMZ survives failover," or, "Yah, failover breaks all SSH sessions."
I'm stuck at asa 5505 nat, port forwarding configuration Here is what i need:
host1: 192.168.1.1 service tcp/100 >>>>> public ip 1.1.1.1 service tcp/100
host2: 192.168.1.2 service tcp/200 >>>>> public ip 1.1.1.1 service tcp/200
host3: 192.168.1.3 service tcp/300 >>>>> public ip 1.1.1.1 service tcp/300
So people from remote just need to use 1.1.1.1 public ip to access all the ports on three different inside server.I can do this on my old ASA 5505 with 8.0(4). Looks like there're lots of change from 8.0 to 8.4.
At the end of the day I simply need to upgrade the license on my ASA 5505 v7.2.4 (upgrade will come later as part of a larger project) to allow for >10 Inside Hosts. From what I've read there seems to be a 50 license upgrade out there. Can this be purchased directly? From whom? Will it only affect the Inside Hosts number and not affect any other licenses, configurations, etc. Just being overly cautious since this is way outside of my normal realm.

I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.
I have recently bought two 1800 cisco routers and have tried to connect them over wan serial link, but I am having problems when trying to access resources on the other side. I am a newbie to cisco and I wonder if the problem is with the configuration or the new routers or the serial link between the sites. Below is the show-running config results I have done on both routers; I can ping the serial interfaces from both sides and remotely, but I can't ping hosts or FE from other side.

We recently had the Aironet 3502i APs installed in our infrastructure and are having a bad time with hosts connecting to them. The controller sees them, they have an IP, they are showing a solid green light, but you cannot get devices to connect. If you reboot the device you get about 5 seconds of connection and then it disconnects. The only cure seems to be rebooting the APs, but I am baffled why this keeps happening. The installer is blaming our devices, but it is happening to laptops, thin clients, and even cell phones. From what I've seen, everything works fine until, i believe, the device tries to refresh it's lease and is unable to do so.
View 6 Replies View RelatedI have a BEFSR41 (wired) router. On the LAN side, I'm using all static IPs, and have the local DHCP server turned off. On the WAN side, I'm using DHCP. When I plug my laptop (which runs Windows 7, and has a static IP set up) into the router, sometimes I can't connect to any hosts on the WAN side, even though other machines on the LAN side can connect to hosts outside. If I run Wireshark, I see the following happening over and over. [code] When this occurs, the laptop can nevertheless connect to the embedded web server running on the router, and, there, I can tell the router to release and renew its WAN-side DHCP lease.

I'm running tcpdump on the server on port 25 and... nothing happens. The traffic is not going through.One thing that I've notices in debug ip packet is this line:
s=1.1.1.1 (Vlan1), d=192.168.101.200 (Vlan1), len 52, rcvd local pkt
shouldn't source be internal vlan1 IP - 192.168.101.1?
