Cisco Firewall :: Passive FTP With A 5505
Jan 4, 2012I have a few remote locations that use a Cisco 5505 to connect to my server through a VPN Tunnel. When they establish a connection through the tunnel they use FTP with the PASV command and successfully send and receive data. No issues. The same remote locations will connect to external FTP sites without a VPN tunnel and attempt to use FTP with PASV and the connection fails after the PASV command is issued.Also, when these sites connect to my FTP server all their internal addresses are configured with a Dynamic HIDE NAT. They don't use this NAT rule when they connect to other FTP sites.
The question is why would an FTP connection through a VPN Tunnel work with PASV, but on a non-tunneled connection the Cisco 5505 blocks the connection.I would think that the connection should drop in both scenarios. What makes the VPN Tunnel connection special to prevent the connection drop? (I just learned about the fixup protocol with the group policy change to resolve the problem. So I can resolve the issue. But I'm interested in knowing why there is a discrepancy.)I did ask our network team and they thought it was somewhat strange too.
Cisco Firewall :: ASA5505 For Passive FTP?
Apr 18, 2012setting up ASA to allow passive FTP connection! I can get the FTP client to connect but it does not pull the directories. I have opened 21 and range of 55536-55566. I had some trouble gettting the range opened and saved. Normally with other small business routers (GUI) I make sure those ports are forwarded and ftp works.
Is the ftp inspection killing connection or is it my config?

Cisco Firewall :: Cannot Use FTP Passive / Active Of ASA5505
Sep 12, 2011Users cannot download some files from a FTP in a software over VPN Explanation users work with a program and inside the program they download claim (the software goes to the FTP and download the file)
But the program returns an error 3018 in FTPGET. If the user goes to the old PPTP VPN it works like a charm so the problem is the Cisco VPN.
I cannot post my complete config but we use the filter vpn value to associate a special access-list to a user.
The user that has this problem has this as an access-list.
access-list 201 extended ip permit 10.250.128.0 255.255.255.0 192.168.202.0 255.255.255.0
I've made some research and i've added this info
policy-map global_policy
class inspection_default
Inspection ftp
Still doesn't work.
I have to add that normally the internal network is 2.0 and not 202.0 but since we have user with 2.0 at home we had to do this.
So when a user sends a request to 202. the cisco fowards it to the Juniper inside the network and it translate it back to 2.0 Also that is the ONLY thing that doesn't work. The client can work all day on that program and it will work #1 exept when she does the claims
I am also been working on this VPN for 2-3 months without any problems.
Cisco WAN :: 5520 - Connect Router To Passive Firewall?
Jan 28, 2013I had a design question, Currently we have a active/passive asa 5520 firewall setup. We have our edge router (3845), on which Gig 0/0 connects to the internet, Gig 0/1 connects to a port on the active firewall. We also have a one port fast ethernet card on the router.How can i use the fast ethernet port on the router to connect to the passive firewall, so that if the active firewall fails, there is internet connectivity through the fast ethernet port on the router.

Jan 12, 2012i have a problem with a Failover Pair of 5510. The Boxes run with the software version 8.2.5.
If the Active ASA goes down, the Standby ASA switch to Active.
If i switch on the old Active ASA, both ASA are Active. This problem don't solved with the command 'no failover active' on the Standby box. This problem only solved with the command 'no failover' and then 'failover' on the Standby box.
Cisco Firewall :: 6500 - Passive FTP Through 2 FWSM Contexts Via VRF Instance
Mar 26, 2012I'm having problems getting FTP to work through two FWSM virtual contexts which are connected via a vrf. All this is configured on a 6500 switch with the FWSM running 3.1(4)
CLIENT-----CONTEXT_1-------VRF------CONTEXT_2--------FTP_SERVER
At the moment we can make the control connection but when we issue commands the connection times out.
Looking at the logs we can see the initial connection made to the server on port 21 from the client, this is also seen on the second firewall context (nearest the FTP server). The data channel is then seen on the first context, made using high src & dst port numbers and initiated from the client, successfully passing the ACL/Inspection, then on the second context we see the connection being denied by the incoming ACL on the second contexts interface connected to the VRF instance.
The rules are identical on the contexts and have been made by copying and paste the rule using CSM, we are using the predefined service group 'FTP-Group' which contains both tcp 20 & 21. FTP inspection is at default on both contexts.
We have tested with Win XP (capable of Active FTP only) & Firefox 3.6.12 which is the connections we are seeing in the logs trying to do Passive FTP.
Is this a problem with teh contexts randomizing sequence numbers or TCP Normalization? Or do we just have a problem with the Inspection engine on one of the contexts (I would have expected to see this on both contexts if it was a bug).

Cisco Firewall :: VLAN Communication On ASA5510?
Aug 10, 2012I have a working environment but wondering if there is just a better way to accomplish what I am trying to do (without a layer 3 or 4 switch). Basically I have a few sub interfaces on my Cisco ASA5510.
Now what I do need is some of the VLANs to communicate with specific devices on the different VLANs. So for example I need computer 1 from VLAN 5 to communicate with 192.168.10.5 from VLAN 10 on ports 80 and 443.

Oct 23, 2011I have a Cisco ASA 5510 configured to access the internet, with an:
inside interface (ethernet 0/1) 130.130.0.254 and outside interface (ethernet 0/0) x.x.x.x
I have now configured another inside interface (ethernet0/2) on ASA with the IP 172.16.0.254 and I have connected it directly to another switch with a management IP 172.16.0.5.
The problem is that the two inside interfaces (130.130.0.254 &172.16.0.254) cannot communicate with each other thus the e0/2 172.16.0.254 interface cannot access the internet.
Cisco Firewall :: ASA5520 Intra-interface Communication And DNS Rewrite?
May 29, 2011Recently, I deployed ASA 5520 as our company firewall, everything was working fine except two main problem I still can not resolve them after I did a lot of research.
1. DNS rewriting - The internal user can not access the DMZ or internal server by put in the domain or external ip address. such as [URL] will resolve our wan ip address 210.0.0.83 ( internal ip address is 192.168.1.21 ).I used static (inside,Outside) tcp 210.0.0.83 https 192.168.1.21 https netmask 255.255.255.255 dns, but it will not work. We have our internal DNS server, but don't want to just add the domain as a record. Is there anyway to get the internal user to access Internal server and DMZ server through the public domain?
2. We also have an internal multiple subnet, another router was conneting to ASA firewall inside interface and using ip address 192.168.1.223, another subnet 10.1.15.16/28 is behind the this router, for the users in subnet 192.168.1.0/24, they connect firewall inside interface directly.I added an static route and intra-interface permit route inside 10.1.15.16 255.255.255.240 192.168.1.223 1same-security-traffic permit intra-interface I also added access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0 10.1.15.16 255.255.255.240access-list inside_nat0_outbound extended permit ip 10.1.15.16 255.255.255.240 192.168.1.0 255.255.255.0nat (inside) 0 access-list inside_nat0_outbound The internal users on 192.168.1.0/24 can ping 10.1.15.18 but can not telnet to 10.1.15.18 22. If I set 192.168.1.223 as one of the workstation on 192.168.1.0/24 default gateway, it can telnet to 10.1.15.18 22 without any problem.
Cisco Firewall :: ASA5505 Alias Secondary Subnet / No Communication Between Them?

Cisco WAN :: 1941 - ASA 5510 Via VPN Tunnels For Communication Back To Servers Behind Firewall
Jun 20, 2012I am setting up a network that will use the 1941 router with a cellular card (HWIC) to connect to the Internet for communication with remote stations in the field. The 1941 has a static IP address (166.142.xxx.yyy) on the Internet provided by the ISP (Verizon). The 1941 is connected via ethernet to the ASA5510. The end goal is to have the field cell routers (Digi Transport WR-44-R, also static IP) connect to the ASA5510 via VPN tunnels for communication back to the servers behind the firewall. I'm not sure exactly how to configure the 1941 so that the remote router can connect to the ASA using the public IP of the 1941 router. I have the 1941 working stand alone and can connect to the Internet and pass traffic, but I tried a static NAT to translate the public IP to the private IP of the ASA and cannot pass traffic. below is part of the 1941 configuration: [code]
Do I need to use VLAN bridging to accomplish the task or am I missing something with the NAT?

Apr 25, 2012Currently we are using a single connection to our ISP and in the coming months will be moving to a two seperate connections (to same ISP). In our current setup we utilize active/passive ASA's (5520, single context) and would like to utilize that going forward as well, the reason being is our DMZ's all hang off of these ASA's and we have fiber connectivity between our datacenters.Our main datacenter and DR Datacenter are basically one big LAN with fiber between them, so we have our DMZ networks at both locations currently with both terminating in our ASA's. That way if the ASA at our current site fails the DMZ's are still accessible via the secondary firewall at our DR facility.

Cisco WAN :: 2921 - Network Design With BGP And Active / Passive ASA's
Mar 1, 2012The following diagram is showing what I "Plan" on doing or "Hope" I can do. This is the most complicated deployment I have taken on in my profession, and Honestly it is very exciting, but had some questions.
1. The network between the ASA's and Routers, is that suppose to be a Private network or Public Network? I have to assume Public because I want my ASA's to take care of the NAT.
2. ASA's are runing single context Active/Standby so what way will the ASA push out going traffic?
3. The routers need to know about each other in a BGP configuration, correct? We accomplish this using iBGP so will that traffic need to be allowed through my firewall to allow the routers to share that information, or should these routers be talking to each other outside the firewalls?
Is this design possible? I am sure there are limitations as always, just trying to wrap my head around the flow of traffic and where to start.
Additional Details/Requirements -
BGP routers are 2921's that I have control of. Both routers have 4 port GigEtherswitches in them.
ASA's are Active/Passive and cannot be Active/Active due the limitations of the Active/Active Design (VPN limitations)
Both ISP's must be used for outbound traffic, I would like to be able to load balance, but can send some traffic one way and the rest of the traffic the other way based on Routes.
ISP's are not Symentrical, one is 50mbps and the other is 250mbps.
All NAT should take place at the ASA's
Additional Questions:
The routers that have gig etherswitches, can they run HSRP?
Should I be putting Layer 3 switches between the routers and the ASA's instead?
Where should I run my iBGP communication for the routers?

May 29, 2011I've been having a problem with my cisco routers (7600s) where sub-interfaces that we create for ldp tunnels are added automatically to the main ospf process as no passive when created. In order, here is how to reproduce the issue:
- Configure ospf process as "passive-interface default"
- Configure interfaces that have to be active as "no passive-interface blah"
- ospf works as expected.
- Create new sub- interface somewhere with encapsulation on a certain vlan for xconnect.
- New sub-interface gets added as "no passive-interface" in main ospf process.
- When adding a new port-channel interface, behavior is the same.
Is that normal for cisco, should I continue removing sub-interfaces manually every time from the ospf process?
