Port Redirect With Default Ports On Application?
Apr 26, 2012
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.
site1.sytes.net:90
site2.sytes.net:91
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.
server1.sytes.net:25566
server2.sytes.net:25567
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?

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'm trying to connect to connect to OpenVPN server from my Ubuntu 11.10 machine. I use the following command to do it (under root user):
openvpn --config /home/vladimir/client.ovpn
Everything seems to be OK, it connects normally without any warnings and errors, but when I try to browse the internet I see that I still use my own IP address, so VPN connection doesn't work. When I run openvpn command, it displays the following message among others:
NOTE: unable to redirect default gateway -- Cannot read current default gateway from system
Below is full output of openvpn command:

I have a problem configuring URL redirect on ACE 30 (Version A4(1.0)).When a user enters IP address or a name of a service [URL], the ACE module should redirect him to the page [URL]. Here is my non-working config:
access-list OUTSIDE line 8 extended permit tcp any any eq https access-list OUTSIDE line 16 extended permit tcp any any eq www access-list OUTSIDE line 24 extended permit icmp any any
probe http Test_HTTP_1 port 80 interval 60 passdetect interval 30 passdetect count 2 request method head url /index.html expect status 200 200 open 1
rserver redirect URL_Redirect_01 webhost-redirection [URL] 302 inservicerserver host S1 ip address 10.0.0.2
inservicerserver host S2 ip address 10.0.0.3
[code]....
it works, ACE load balances to rservers. Of course, user must enter full url.With redirection configured, user recieves HTTP url redirect message with correct address [URL], but his browser does not display the page. Even directly entered full url does not display it while redirection is configured.Alternatively, does ACE30 already support url rewrite?

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've configured WCCP2 on my ASR1002/ESP2 and works fine. But got error log since I changed redirect ACL entries. Check on Cisco seems it a known bug?[URL] And seems any change on WCCP not take affected anymore. Even I removed all WCCP configure on my router, but my cache engine still got the redirected packet!?

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"?

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.

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

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 need to redirect all http and https traffic from one source in a dmz network, to port tcp/8080 on a proxy server on the inside network.
The source device doesn't handle proxying very well, so i've been advised to redirect the tcp/80 and tcp/443 ports to tcp/8080 as it passes through the firewall.
Scenario is thus:
PIX 515E 6.3 (5)
DMZ server: 172.31.255.250 (Real IP), 10.44.181.236 (NAT IP)
Inside Proxy server: 10.44.132.28 (Real IP), 172.31.255.110 (NAT IP)
I've configured a static NAT redirect using the following command: static (inside,dmz) tcp 172.31.255.110 www 10.44.132.28 8080 netmask 255.255.255.255 0 0
When I try to add the next command of: static (inside,dmz) tcp 172.31.255.110 443 10.44.132.28 8080 netmask 255.255.255.255 0 0
I get the following error: ERROR: duplicate of existing static
Is there a work around for this at all or am I stuck with the limitations of the software?

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'm trying to configure a 3com 5500 switch with default ports for each vlan.The default ports are connected to IPS/IDS and do not have an IP address. I have a trunked esx host coming in and want to send traffic to specific ports based on vlan id - one port per vlan (10 total). Right now all I'm getting on the ips/ids is stp and arp traffic.

So here is my network.
ASA5505--->Cisco1841--->Cat2960
Code
ASA asa831-k8.bin
Cisco 1841 c1841-adventerprisek9-mz.151-4.M2.bin
Cat 2960 c2960-lanbasek9-mz.122-55.SE1.bin
and here is my dilemma.
I can SSH from the internet to my ASA on default port 22, directly to my public IP. I can SSH from the internet to my Cisco 1841 on port 2001. I can not however, SSH to my Cat 2960. From what i can tell, on the Cat2960 i can't change the default port 22 for SSH to different port, just like i did on the Cisco 1841. I looked to see if I can change the default port for SSH on he ASA, it does not look like this is an option.
The bottom line is that i want to be able to SSH to all three devices from the internet. I only have one public IP. As of now, what i can do is only SSH to the ASA on default port 22 directly to the public IP and Cisco 1841 on port 2001. It appears that changing the default SSH port on Cat 2960 is not an option. It also appears that I can't change the default SSH port on the ASA, if i could, i would and then i should be able to SSH to the Cat 2960 on port 22. No matter what i did on the ASA, it always listens on port 22 for SSH connections.
show asp table socket
TCP 001f549f <<pub IP>>:22 0.0.0.0:* LISTEN
how do i make it listen on different port?
Here is relevent config for SSH for cisco 1841 (port forwarding)

I have a strange behaviour with some ACE30 running A5 release :
Setup is in bridge mode, working correctly with a default gateway set in the context.
For some reason, some return traffic is being routed on the ACE instead of being bridged.
On what conditions would the ace decide to route the traffic of simply bridge it from the server vlan to the client vlan.

We have set of PC's who will be connecting either RA IPsec or SSL VPN to another location. On our site, our perimeter device is an ASA 5520 8.2(3). The interfaces on this ASA doesn't have Access Lists applied, so from what I understand, there is a default policy applied globally (class-default). Now my question is: If we set up vpn clients on our pc, are the ports used by the clients to the VPN server allowed by default or do we need to tweak the class-default?

Since the ACE supports only static routing, when pointing a default route from the ACE what is your preferred method when using multiple 6500s with an ACE in each in a failover scenario to prevent just pointing at one 6500? Static route to an HSRP address? Multiple static routes on the ACE, etc?

I'm setting up an ACE 4710 in our test lab before deploying in production. Do the test web servers I am using need to use the ACE as their default gateway? The are currently configured to use a multilayer switch on their vlan as their gateway but I'm guessing the ACE needs to see the return traffic for load balancing to work correctly?

I am new to the 4710 appliance.Apart from the 4 GE 'data' ports, there are 2 Ethernet 'management' ("console") ports. I find the description in the "quick start guide"somewhat confusing. URL, Is a first-time serial connection (at least to run the initial config. script) mandatory? Or can you obtain the same result via one of the 2 Ethernet management ports and using a default ip address (192.168.1.10 ? When running the initial config. script (only possible from the serially connected console i suppose), you have to select your management port. Why does the system in step 5 proposes you 4 ports, and not just 2? I suppose the intended port for management is one of the 2 management ports, not one of the 4 data ports?

Currently migrating from a CSS to a new ACE for all our inbound ssl connections.
On the CSS, I could define multiple backend services, different tcp ports and 1 IP.
ex.
service TEST_HTTP22
protocol tcp

But now I have to define each backend web server as an RSERVER and it doesnt allow me to configure 2 rservers with same IP.

I'm used to using full blown cisco IOS/CLi and I'm new to the SG 300 switches. How you can default a port config? The 'default int ##' command doesn't exist on the CLi and I can't find anywhere in the web gui for this.Finding it very frustrating having to go into each port and get rid of all the commands.I can't default the switch as its live and was to reconfigure most of the ports which are now unused.
