Cisco Firewall :: ASA5540 Port 80 Redirect To Https
Dec 21, 2011
Windows IIS server configured behind a Cisco ASA 5540 listening on port 443 currently. Access-list and static translation configured. I have been ask to redirect all port 80 calls to port 443 for this web site only at the firewall. I have suggested moving it behind our content switch with negative results. Can we do this at the firewall level? how to accomplish the redirect for a single site. 8.2.4 is current code
Right now, in my network there is no proxy server and all users go straight through the ASA to access internet. I would like to put a squid with dansguardian (for web filtering). Steps in getting all http and https traffic from ASA go via my squid?
i have ACE 4710 appliance that terminate SSL and the connection to the servers is http.
The ACE (one Armed) is load balancing between two web servers and i am using stickness in order to take the connection on the same server based on cookie.I can access the website either by http or https., where on the web page there is a login credential to access using username and password.
When i access the website using https everything works fine and i can login to my account in https mode.When i access the website through http and login to my account the URL is redirected to https...normal because i am using action-list to rewrite the http into https. But when i exit the browser and access the website again using http it is not redirected to https(although i see that i am still login into my account i can see all the inforamtion in my account).
The customer wants the connection to be https even when i exit the browser and access the website again (within short time before the cookie exipres)
For a CSS with a SSL module (performing SSL termination) - is it possible to impliment a redirect on https URL to send to equivalent http URL.If my understanding is correct, the CSS will do SSL termination and then use an http content rule on the resultant http stream as it is recursively handled by the CSS ? This would mean that the SSL module has no way of seeing/acting on layer 5 and above data (i.e. picking up on a specific URL) and can not itself issue a redirect - i.e. you could not associate a redirect statement or service with the following ssl content rule ? [code]The CSS would instead rely on a http content rule to impliment a redirect - i.e. you would have to associate a redirect statement or service to the following http content rule instead?
But if the CSS is already handling traffic for existing url... traffic that is going to cause a loop when a client goes direct to. url...I realise the requirment is uncommon / a bit convoluted, its one of those don't ask type scenarios - aimed at achieving a specific requirement.Would the ACE 4710 be able to handle such a scenario any differently ?
I am trying to make a redirect from http to https. the goal is whenever a user writes in http://10.80.199.71 it should be redirected to https://10.80.199.71 I am just haveing some trouble making it work.
I have got a Cisco router connected to a LAN and to the internet.I was wondering if I could nat https traffic from inside to internet to a local server (Proxy) on a given port for example tcp 8080.
int tunnel0 ip address 192.168.0.1 255.255.255.0 ip nat inside int fa0/1 des internet connexion ip address 41.x.x.x.x 255.255.255.248 ip nat outside ip access-list extended Proxy_Redirect permit tcp 192.168.0.0 0.0.0.255 any eq 443
I am setting up an ASA 5550 8.4 and asdm 6.4. Last thing I am missing is to get the static nat rule done for https. Done it with asdm and cli and always end up with "error: nat unable to reserve the port". Looked around the Net so far and changed the http enable port to 4433. ASDM access is only configured for inside and mgmt port. Disabled under RA VPN all checkboxes in clientless ssl and any connection profiles since IKEv1 is used for vpn access.
I am configuring an ASA5540 firewall for a client, only difference to usual being that it is to run in Transparent mode. I have looked through for an EAL4 transparent firewall config guide but found nothing and therefore assumed that the usual one would be used.The clients security bod has now come back and insisted MAC filtering should be used but I can find no reference of this anywhere. Does MAC filtering is required to make a transparent box EAL4 compliant and if so where I can find documentation supporting this?
Our company uses a commercial copier monitoring package called FMAudit to obtain meter readings from our clients' copiers, and it uses a feed to send the readings back to us. We have used port 90 for this purpose.Due to a recent server crash and emergency reconfiguration of our network, we have moved our FMAudit central server from in-house to a hosted service, with of course a different external IP address.
Without interfering with our other systems, is there a way to redirect JUST PORT 90 to another IP address external to our own? I don't care if it has to happen at the router or server level. We are using Server 2003 and a Cisco 887VAW.
I'm running several game and file servers via a dynamic IP, which I unfortunately cannot change to a static connection for several reasons. I've solved this by using No-IP, which is a Dynamic IP resolution service. This solved the first part of my problem - I can give people IP's for their websites, such as myfreemusic.sytes.net and so forth, but they all HAVE to append their ports to the url - i.e.
My main problem right now is the game servers - I'm hosting games that default host to 25565, and though I can change the ports the server hosts from, I must give those who want to connect the ports at the end of their urls, i.e.
I know DNS is essentially agnostic when it comes to ports, so no solution there. And I don't think the game (Minecraft vis-a-vis bukkit) supports SRV records, and even if they did, I'd have no idea how to configure them. How can I resolve static urls redirecting to a dynamic IP by pointing them to ports?
To simplify the question -
How can I make server1.sytes.net resolve to port 25566, and server2.sytes.net resolve to port 25567 when the default port is set to 25565?
Redirecting a Domain to a IP:Port I host game servers for friends and strangers alike, but i'd like to make it easier for them all and give them dedicated IPs. Right now I include domain redirecting, but to connect to their server, they have to put in "example.com:xxxxx", x meaning their servers dedicated port. Is there any way that I can redirect a domain directly to "IP:Port"?
I was working with Motorola SB6120 cable modem regarding an odd power cycle issue (it would power cycle randomly for 24 hours). While trying to diag the issue, I was taking a peak in his router config and found a port set to forward as:
Application: Comcast Port From: 888 Protocol: Both IP: 192.168.100.1 Port To: 80
I understand that his modem admin page is now available from the internet. He said his friend set this up to "modem", but I don't see any advantage of having this done. At this point what are the other advantages of forwarding such ports?Another key note: When the port forwarding was disabled, suddenly the power cycle issues stopped.
I had a working vpn configuration between a local and a remote router; the remote router is not under my administration.Now I moved the vpn termination from my side to an ASA5540 software version 8.0(3). The tunnel is up but there is no reachability. The "show crypto ipsec sa" on the ASA shows encapsulated packets but NO decapsulated packets! Routing and no_nat are properly configured.
I want to redirect internal web traffic (browsing) to an external web server for Web, Virus and Spyware filtering. Those externals proxies are running in 8080 port. I have one ASA firewall and a Cisco 2600 router. I was thinking in doing PBR in the router but in the next hop I can only set one IP, not an IP and a port. So how can I redirect web traffic to an external proxy listening in 8080 port?
I have an ASA- 5585X (v.8.2.4) directly connected to an upstream 6509, which is running EIGRP. I configured the ASA for EIGRP with same AS# and network numbers and no auto-summary. Here are the log messages I got:
Mar 8 15:11:08: %PIM-5-NBRCHG: neighbor 22.214.171.124 UP on interface Vlan150 (vrf default) Mar 8 15:11:08: %PIM-5-DRCHG: DR change from neighbor 0.0.0.0 to 126.96.36.199 on interface Vlan150 (vrf default) Mar 8 15:11:11: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 188.8.131.52 (Vlan150) isup: new adjacencyMar 8 16:16:08: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 184.108.40.206 (Vlan150) isup: new adjacency Mar 8 16:18:54: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 220.127.116.11 (Vlan150) is down: K-value mismatch
I lost my SSH connection to the upstream 6509 and couldn't get it back. Luckily I didn't lose my ASDM connection to the ASA, so I disabled EIGRP and went to look at the logs on the 6509.
What causes a K-value mismatch, and how to I rectify the situation?
I have this 2x ASA5540 firewall and notice the it is configured with a standby ip. The firewall is run in Active/Passive mode.However, the standby ip of this firewall is not point to the secondary firewall and vice versa for the primary firewall. [code]
1) May i know how is this configuration valid in the first place? I have checked through the configuration. None of the configuration is related to this ip address.
2) Can we remove this standby ip address on both the firewall and correct to the correct primary and seconadary ip address in both firewall?
3) We tried to use this ip address but cannot be used ? Is it related to the configuration of the standby ip address.Do note that the ping to this ip address x.x.x.120 is unreachable.
i have two CAT3750 need to place in L3, and it supposed that used as L3 switches by SVI for L2 routing, and I want to these two configured as redundancy by HSRP. but now I can only have one ASA5540 to connects these of L3 switches.
so, here is my questions:
1. does ASA5540 support multi vlan?
2. does it support spanning tree protocol?
3. if I've choiced to use trunking between two L3 switches, does it can pass through HSRP hello msg?
I upgraded our ASA5540 to 8.4, THEN noted the increased requirements for Memory. I purchased the 2Gig upgrade, but when installing in the Primary unit today, noted that there were 4 slots. Slots 1/3 had 512Mb modules, so I installed the 2 x 1Gig modules in slots 2/4.
The ASA5540 came up clean, and it "sees" the entire 3Gig of memory.
My question: Is this a SUPPORTED configuration? All documentation I have read only mentions 2Gig of memory. Also, If I had FOUR x 1Gig memory modules, would the ASA5540 support the 4Gigs of memory?
We have ASA 5540 with 8.2 SW. We are trying to download a file (3 MB pdf) from https session which fails if done behind the firewall. In case, the client bypasses firewall, the file gets downloaded as usuall. Interesting thing here to note is that when client is behind the firewall, its takes a long time to download the file and the file size always 312 Bytes, of course its a corrupt file.
I have requirement received from one of my customer. the part number given as ASA5540-AIP40-K8, same time requesting for addition of another 4Port GE Module (i believe its SSM-4GE Module). Is any option to add this module in to the above specified model (ASA5540-AIP40-K8).
As per my understanding the ASA5540 have the option to add 1 additional module only, so if we AIP-SSM module, we don't have any free slot left with to add another SSM-4GE Module in the firewall.
i am not getting even the option to add SSM-4GE in the ASA5540-AIP40-K8
I am migrating firewall fortinet to ASA5540 with inside (192.0.0.0/24), dmz (192.168.0.0/24), and outside (x.x.x.x), but the users of inside network gain access to the aplication for two ways: the first way is trough routing between inside and dmz, for example 18.104.22.168 to 192.168.0.20, and the another way is trough static nat between inside and dmz for example 22.214.171.124 to 126.96.36.199 (192.168.0.20 static nat). Is posible in Cisco configure that? because when i configure only firewall route the first way is OK, but when i add the second way only nat is work!
I am facing problem with ACE configuration. I want to redirect 443 traffic to my Proxy Server. But I am not able to do this. I want to redirect only subnet 192.168.80.0/24..Then only it is working but I dont have to have this policy to be applied on all the users only one subnet I want to have under HTTPS policy.
how can I apply the policy only on specific subnet so that port 443 traffic can be redirect and rest of all subnets can go direclty to Internet.
I have an inside network using PAT to one outside address. Our DNS server is on another local, but outside address. I can't get the inside network to successfully get addresses.I have another inside address that just uses the wirewall and gets addresses just fine from the same server.I have the box checked in ASDN that enables DHCP on the inside interface and points to the correct DHCP server,PAT service is working properly if I use a hard coded address for a machine on the inside network.This is an ASA5540 with 8.3(2)
My Expertise with Cisco ASA is Very less. I have observed Input errors in a Couple of Interfaces in Cisco ASA 5540 Firewall. [code] I need to Clear the Input errors on this particular Interface.Will Clear interface GigabitEthernet 0/0 will work?
I am attempting to FTP to a remote site through a IPSEC tunnel.When I am transfering large files the ASA5540 is showing syslog errors stating "connection timeout". What I think is happening is after about 1 hour the firewall is closing the connection control port for the FTP session and neither end is notified so eventually the transfer is stopped.What do I need to modify in the FW to accommodate these larger files?
