Cisco Switching/Routing :: ASA 5520 - Can't Ping / Pass Traffic Through Interfaces

Apr 17, 2012

I've just started a CCNA course and my lack of knowledge has me a bit stuck. My network is comprised of Cisco components and I'm semi familiar with them just from reading and looking through options. I currently am using a Cisco ASA 5520 on my network and I am trying to join another network via one of the interfaces. My network is 192.168.0.0 255.255.0.0 and my inside interface is 192.168.1.1 255.255.0.0. I enabled a second interface using a static ip of 10.0.0.1 with a subnet of 255.255.255.128. Connected to that interface, I have a Fortigate firewall at 10.0.0.2 255.255.255.128. I can ping just fine from the Fortigate network to the 10.0.0.1 interface on the Cisco ASA 5520 network, but I can not ping the 10.0.0.1 interface (or anything past it) on the ASA 5520 from any computer on the Cisco network. I've read that ACL's and NAT have to be done as well as enabling traffic between interfaces with the same security levels. (both interfaces have security levels of 100 and the option is checked to allow traffic).

Note: each network has it's own internet connection. The connection is to share information on servers on both networks with each other.

Cisco Firewall :: ASA5505 Does Not Pass Traffic

Cisco Firewall :: ASA5505 Will Not Pass Traffic?

Nov 15, 2011

I am trying to setup my very first ASA5505 and I cannot get it to pass traffic from the inside to the outside. I am not using NAT/PAT. Here is what I have done so far.
 
ASA5505(config)# interface Vlan 1ASA5505(config-if)# nameif insideASA5505(config-if)# security-level 100ASA5505(config-if)# ip address 33.46.132.34 255.255.255.248ASA5505(config-if)# no shut

[Code]....

Then from the asdm I permited everything from inside to go out but I cannot get any traffic through. I can ping the outside if I source the outside interface but not if I source the inside. The logs would not show me anything.
 
I did a packet tracer and it indicates the implicit deny rule at the end of the access-list is stopping my traffic eventhough I have allow rules above it?
 
I also checked the box in the asdm to allow traffic to pass without NAT

Cisco Firewall :: PPTP Traffic Cannot Pass Through PIX 525 7.0(7)

May 6, 2008

i read cisco document:[URL] pptp client is in inside,pptp server is in outside.when i donot use firewall, the pptp connection can establish successfully.but use pix 525 7.0(7) i config:

inspect pptp.
pptp connection cannot setup.
show connection in pix:
pptp tcp 1723 is ok.

gre connection only one "E" flag, E means 'outside back connection'.i try second method:delete 'inspect pptp',permit tcp 1723 and gre traffic from outside to inside, and i have config static nat,but the pptp connection cannot work too.so i think there is a pptp bug exist in pix 7.0(7).

We have an issue where by we connect to various customers and the Cisco IPSEC remote access works fine from our LAN through an ASA5505 to a customer site.We have 1 customer that we have some issues with. We can connect  from the LAN through to the customers VPN, authenticate and establish a tunnel but in we cannot pass traffic. When we try from outside of the office on a public internet connection the VPN works fine. What could cause this issue?

Cisco Firewall :: 5520 L2TP Pass Through To Windows Server

Oct 2, 2012

We have a Cisco ASA 5520
 
We are attempting to setup RRAS on Windows 2008R2 using L2TP. Server is on the inside of the network at 10.10.10.20 our ASA is 10.10.10.1 its outside interface is 68.0.0.0.3/28.
 
I set a static NAT rule to allow all traffic pointed at 68.0.0.4 to be directed to 10.10.10.20 and have ACLs allowing the following.
esp, ah, udp/500, udp/4500, udp/1701
 
Mac Clients have no issues with but windows clients seem to hang and never connect. I know the ASA configuration is somehow to blame, if I attempt to connect to LAN IP (10.10.10.20) from withn the same network every thing works fine (making sure all the Windows Issues are covered).We have 2 other IPSEC tunnels established to teh ASA from our COLO and a Satalite office, not sure if this makes it any harder.

Cisco Firewall :: Pass Management VLAN Traffic Through ASA 5510 In Transparent

Mar 10, 2013

We have a small cisco 1800 series workgroup router that seperates our network from the outside world.  The data coming into our network goes into the router on interface fa0/1 and comes out on interface fa0/0.  fa0/0 is split into 2 sub-interfaces (fa0/0.2 and 0/0.3).  These sub-interfaces correspond to a desktop and server vlan on our network.  The workgroup router is connected to a 3560G trunk port (we'll call it switch 1) and switch 1 connects to another 3560G (we'll call it switch 2). Recently I was asked to add another layer of security to our network by installing an ASA 5510 firewall and forcing certain types of traffic to authenticate using their domain credentials for our network.  The firewall was set up between the router and switch 1 in transparent, multi-context mode.  There are 2 security contexts, 1 for the desktop vlan and 1 for the server.  Both have the same security settings applied to them since we want the same behavior regardless of whether they are trying to access the servers or the workstations.

Cisco Firewall :: ASA 5520 - Allow Traffic From DMZ To Internet And Block Traffic?

Apr 29, 2012

I have an ASA 5520 with the below config
 
Gi0/0: outside (Internet)
Gi0/1: inside (Internal users)
Gi0/2: DMZ (web servers, ftp, Mail etc..)
 
I have a SMTP relay deployed on the DMZ for mailing. I have also a mail servers installed in the internal lan,
 
I want to allow trafic from dmz to reach internal lan, and i want normally also allow stmp relay from dmz to reach Internet.
 
How can i block trafic from DMZ to reach Internal Lan (instead of smtp) if the to allow trafic from dmz to internet i must put ANY in the policy?
 
For allowing trafic from DMZ to reach Internet, the policy must be DMZ -----> ANY ----->Services., this policy means DMZ can implicity reach Internal Lan?

Cisco Firewall :: ASA 5520 - Create Network Object For Range Of Hosts?

Oct 25, 2011

I'm migrating our network objects from our current firewall to a new ASA 5520 configuration. I'm using ASDM 6.4 for configuration.
 
We have a range of IP addresses for hosts that we need to add to a firewall rule/ACL. In the previous FW software I could create an object that was a range of IP address. For example there is an object called emailservers that is defined as 192.168.2.25-192.168.2.50.
 
Is there a way to do a similar thing on the ASA 5520?
 
I can see how to create subnets, but in this case I only have a range of IP addresses, no subnet mask.

Cisco Firewall :: ASA 5520 - VPN Traffic Is Getting Dropped Through Firewall

Our Local Network is behind the CISCO ASA Firewall.Whenever we are accessing to Client VPN server,it is getting connected but after few Minutes (May be 5/10/30 Min),the sessions are terminating. The same traffic through PIX is no issue , only with ASA Firewall. See the following Error and request you give the possible root cause for this.

Cisco Firewall :: 5520 VPN Traffic Between Interfaces

Jun 12, 2011

Our ASA 5520 firewall is running 8.0(4) IOS.I have an internal L2L VPN terminating on my firewall (from an internal remote site) on ENG interface.With the default "sysopt connection permit-vpn" command enabled, VPN traffic is allowed to bypass the ENG interface acl.The security level on the ENG interface is set at 50.The security level on the destination interface PRODUCTION is set at 40.Inbound VPN traffic bypasses ENG interface acl and since higher-to-lower security level allows VPN traffic to flow freely from ENG to PRODUCTION, it seems the only place to check/filter VPN traffic is an ACL placed on the PRODCTTION interface and set at INBOUND (outbound VPN traffic).

Cisco Firewall :: ASA 5520 8.3 VPN Tunnel Drops Traffic

Aug 23, 2011

We have a 100 Mbps WAN circuit, we have configured an IPsec tunnel between ASA 5520 and Cisco 3845 Router for our DR site replication via Veeam Backup and Replication, it was working fine before, when we established the 3DES tunnel the traffic for certain subnets is dropped after an hour and it stops the replication, although tunnel remains up and we can access the other subnets, as soon as we clear the crypto SA and ISAKMP sessions on the firewall the traffic starts flowing again and then after an hour the traffic is dropped again.So far the testing and differnet configurations we tried are as under.
 
Tried with a different MTU size both on firewall and ESXi servers but nothing happened.Their is no QOS configuration.Checked the utilization on both ends its Noram although their are subsequent 100% spikes on Cisco 3845 but on average it remians at 30-40%.

Cisco Firewall :: Enabling Outbound Traffic Through ASA 5520 8.4(4)1

Apr 4, 2013

We've got a proyect that requires a few thin clients to connect to a remote PCoIP server.
 
Looking to the documentation, the only port required to be open through Firewalls is TCP/UDP 4172, however, we've seen (making interface captures) that it somehow also uses ESP (IP protocol 50).
 
We've got a static NAT translation translating those thin clients to a public IP address, we've created ACLs to allow inbound (shouldn't be necessary as our user is connecting to a remote server) and outbound traffic for TCP/UDP 4172 and ESP and I cannot make it work.
 
I've also enabled IPSec pass-through Inspection to no avail.
 
how should we configure our ASA to enable this kind of traffic?

Cisco WAN :: 1921 Won't Pass Traffic?

Jul 9, 2011

I can telnet to the router and ping places on the inside and outside. However when I connect a laptop to the inside interface I can ping to the outside for a bit but can't open a web page and then connectivity is gone all together. At first I thought it was a NAT issue but I know I am good on that front. I have attempted to change the speeds and duplex settings on the outside interface but it does not seem to work. Again if I take the cable from the outside interface and plug it into a laptop it works fine. The thing that makes me wonder is why can I connect to the outside interface and configure it just fine?

Cisco Firewall :: ASA 5520 - Permit Traffic To Inside Via MAC - Address?

Apr 6, 2011

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.
