I am trying to configure RemoteDesktop on a home lab ASA5505 with IOS 8.4.1 and no matter what I tried, I am unable to remote into a local server behind the firewall. I've searched online and found several threads with solutions online including here at Cisco Support Community forum and have tried them all, but have no success. I'm sure it may be something very simple that I've missed.

I'm having trouble configuring an ASA5505 on version 8.31 code for an IPSec tunnel. I've done this multiple times on 8.2.5 but can't seem to get my tunnel to even attempt to come up on this ASA. Not sure if it's relevent or not, but this remote ASA has never been used for another VPN tunnel before. When I attempt to ping a host on the other side of my tunnel, I just see the following: 8108# sho crypto isa sa

My local network is 10.1.1.X/24 and my remote peer network contains 66.37.227.X/24. I've been working on this for the better part of the day and would love to get it resolved.
this is the first time I am about to configure ACS 5.3 to authorize user group from doing some commands in the "configure mode" while permitting them some other commands. As example, I want to deny them from doing "reload" but give them access to configure "time-range", what happen is, they are denied access to "reload" on the exec mode, but once they went into "configure" mode, they would be able to "do reload"I mean to say, is it possible to manage the subsequent commands to "configure terminal" ?
View 4 Replies View RelatedI have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.
When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.
The ASA5505 configuration is shown below.

i have asa 5505 with the asdm v5.2 (4), and the asa v7.2(4). This platform has a base license. if i upgrade adsm and asa on v6.2(1) and v8.2(2) if I lose my license and that you need to activate them? i configured site to site vpn (this firewall and the another) that i lose my configuration if i upgrade my firewall.
View 2 Replies View RelatedI've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.

Cisco ASA 5505 - >Inernal LAN switch.
1. Internet is connected to Juniper Ge0/0/0 via /30 IP.
2. Juniper fe0/0/2 port is configured as inet port and configured the Internal public LAN pool provided by the ISP. And this port is directly connected to Cisco ASA 5505 E0/0. Its a /28 pool IP address. This interface is configured as outside and security level set to 0.
From Juniper SRX, am able to ping public Internet IPs (8.8.8.8).
Issue:
1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30)
2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.
1, Configured icmp inspection on ASA.
2. Used the packet tracer in ASA, it shows the packet is flowing outside without a drop.
3. Allowed all services in untrust zone in bound traffic in Juniper SRX.
4. Viewed the logs when I was trying the ping 8.8.8.8 in ASA. It says "Tear down ICMP connection for faddrr **** gaddr **

I'm trying to troubleshoot an ASA5505.
The original goal was to block "Mumble/Murmur" (a voip app) traffic, which runs on TCP/UDP 64738, both inbound and outbound, except to a certain host (63.223.117.170).
However, when nothing I tried seemed to make a difference, just to troubleshoot, I decided to try blocking all inbound traffic. I first disconnected ethernet port 0/0 to ensure that it was cabled correctly and the outside interface went down when I did. That worked as expected, so I confirmed I had the right interface and it was cabled correctly.
I then applied a "any any deny ip" rule as the first element in the outside interface access_list, as you can see below. However, it appears to have had no real effect and the hit count is very low (it should be astronomical).

I am configuring a Cisco ASA 5505 firewall.In the office there is 1 x SBS 2008 server and 5 x PCs, all sat behind a Netgear DGN1000 ADSL router.We want to implement a ASA 5505 for added security.I have configured the internal interface of the Cisco ASA 5505 to be 192.168.0.1 - this is connected to local switch. The client PCs use 192.168.0.1 as their default gateway.I have configured the external ASA 5505 interface to be x.x.x.217. [code]Change the current router status from Router/Firewall/Modem to Modem only (Bridge mode). The ASA 5505 has its outside interface connected into one of the LAN ports of the netgear. The lan port has an IP of 192.168.0.254.
View 3 Replies View RelatedI am in the process of migrating a production firewall from PIX 6.3 to ASA 8.4(2). This is going to be a complete firewall rebuild and I will not be upgrading the configs because they have become out of date and very bloated. I am in the process of converting the NAT commands.[code] I am hoping these commands would be enough to replicate the previous functionality. I removed all the static identity NATs because NAT control is no longer in place so those rules are not required. Additionally I didn't re-create the rules that had NAT ID 0 or 1 because it didn't look like they were doing anything. correct way to do the static NAT commands at the bottom.
View 3 Replies View RelatedI am designing a new NAT configuration for an ASA 8.4
On my PIX 8.0 configuration I needed to allow bidirectional traffic between interfaces with different security levels. For example, Inside at 100 and dmz at 50.To accomplish this in 8.0 I used a static NAT command along with any necessary ACLs.
I now need to apply this same 8.0 config for 8.4. With the static command not availablein 8.4 I am unsure of which NAT commands to use to achieve the bidirectional traffic.
what the new command is for NAT in version 8.3?The config i have is from Version 7.2 and doesnt work on 8.3. [code]

I'm having an issue configuring NAT on an ASA running 8.3. 've managed to configure NAT from the Inside interface to the DMZ, using PAT, so that the traffic is hidden behind the IP of the DMZ interface. This seems to work ok.

The problem I have is when I try to configure a rule for traffic that originates in the DMZ back to the Inside. I can't seem to get any traffic to flow from the DMZ to the Inside, and sometimes I manage to stop traffic flowing in both directions!
What would be the best way to configure the return traffic from the DMZ to the Inside.
Is it possible to use IP "aliases" on an ASA5505 to use as static NAT public IPs to private IPs? For example, I have int e0/0 connected to my ISP using a /30 subnet and I have my private LAN connected to e0/1 with a /24 subnet. At the moment I can use the one usable IP from the /30 to NAT to the private LAN. The ISP is also routing a /28 subnet to the one public IP of the ASA. I would like to use some of the /28 IPs for NAT also. Can it be as easy as just adding the NAT commands? I figure I would have to add that subnet to the ASA somehow, no? In other devices (including the SA520) they use a concept called IP aliases whereby you define what additional IPs the device can use in its NAT config. Does the ASA support aliases? Maybe I have to do something with VLANs?

View 3 Replies View RelatedI have 1 network that I'm trying to make secure, and it needs to access 2 seperate networks. I tried using an ASA5505 that I had on the shelf to accomplish this but discovered that I had the basic license and that was prohibiting me from getting my connection to my 3rd network. I scrapped that idea and grabbed an old pix 501 off the shelf to bring my connectivity to my 3rd network online since the 3rd network is only passing ip traffic to a small group of servers on the outside I figure the 501 should be just fine.
So, here's the problem I am running into:My internal network is 10.10.16.0/16, I have a new domain controller with DHCP on it handing out addresses in the 10.10.16.0/24 range.External Network 1 is 192.168.16.0/24. The services I need from that network are primarily in 192.168.0.0 range, however there is a comcast router 75.123.123.123 (Changed of course) that provides high speed internet I need for my www traffic.External Network 2 is 10.1.1.0/16 I have about 4 servers I need to access on this network and that's it. This network has it's own domain and DHCP controller and I've been given a range of ip's to use on this network of 10.1.3.180-10.1.3.189 My switch is just a plane jane 3com switch with minimal management so I am attempting to use my ASA5505 to handle my layer 3 routing.
So here's my issue:ASA5505 (IN:10.10.16.1, OUT: 192.168.16.6): Passes traffic to External Network 1 and to the comcast router, no problem. All my computers on my 10.10.16.0/16 network have access to everything on 192.168.0.0/24 as well as getting full name resolution and www traffic across the comcast router. Can NOT access 10.1.1.0/16 no matter what. From inside the ASA or from on the inside LAN ports. It CAN ping the PIX 501 PIX 501 (IN:10.10.16.3, OUT: 10.1.3.180) Can ping EVERYTHING. Can ping 192.168.0.0/24, can ping 10.10.16.0/16 and can ping 10.1.1.0/16. Set to globally assign the other IP's in my range as addresses for outgoing traffic.Workstations (IN: 10.10.16.XXX DHCP, using 10.10.16.1 as gateway) Can only access everything on External Network 1. ZERO access to External Network 2. ATM I have both INSIDE and OUTSIDE ACL's wide open for both firewalls just to get connectivity going. I will be tightening it up after it is operational.Attached find a log file (Sensetive data removed of course) that contains the sh run and sh ver for both the ASA5505 and the PIX 501.
I just got an ASA 5505 with Cisco Adaptive Security Appliance Software Version 8.0(4) alredy loaded on it. Should I update/upgrade it to the newest IOS release, or is the 8.0(4) good and stable?

I have a asa 5505 Sec plus with 3vlan, inside, outside and dmz.
On the outside i have 5 ip's for my use, and in the dmz i have a webserver that need to communicate with one sql server on the inside.
The "sql" also needs to be accessible from outside and thus has a static nat with a dynamic nat so it replies from same ip as on nat ie 72.72.72.5 webserver is natted with 72.72.72.6
sql inside ip is 192.168.1.2, gw 192.168.1.1
webserver ip is 192.168.2.100 gw 192.168.2.1
sec lvl on inside is 100 and on dmz 50
with a dynamic policy running inside-net/24 to dmz-network/24 translagt to dmz 192.168.2.2 i can get it to ping 1 way from inside to dmz, but not the other way around...
All i need is to open 1 port ie 6677 both ways for this communication to work.
I'm not very familiar with the CLI and do most stuf in GUI (know i should learn CLI, but time doesnt let me)...
on access rules i have just added everything from any to any using , ip, icmp, tcp and udp just to be sure... :-)
I want to make it so if a user tries to use a different DNS server the request will be redirected to the one they should be using.I thought this might work but the ASA doesn't do PB routing
ip access-list extended transparent_dns
permit udp any any eq 53
route-map redirect_dns permit 10
match ip address transparent_dns
set ip next-hop ip.of.your.server
route-map redirect_dns permit 20

The DNS server is windows 2003?Would policy based NAT or WCCP work for this? If so how would I go about it?
I would like to use an ASA5505 as a simple LAN-to-LAN ethernet router. My plan is to configure two interfaces with the same security level and then use the command that allows interfaces with the same security level to communicate with each other. I can get this to work without having to setup and ACLs or NAT stuff.
