Cisco WAN :: 800 Series / Open Port To Specific External Ip

Feb 6, 2012

I have a Cisco 800 series ?I need to allow access to our local server from a specific range of  external ip addresses.I can open port for all external ip using this command:

ip nat inside source static tcp <localserverip> <port> interface <interface> <port
 
But this is not secure as is..Do I then restrict and permit access using access-list? Or is there another way altogether?

Cisco WAN :: 2600 - Redirect Web Traffic To External Proxy In Specific Port?

Jan 18, 2010

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?

Cisco WAN :: Open Port In ASA 5505 Series?

Mar 2, 2013

I need to open ports 9080 and 5280 on my Cisco ASA 5505 firewall and despite doing everything I THINK I needed to do...when I run the utility to check from outside; it is NOT open....I utilize a website called [URL] (very good for these kinds of things) I have added the specific port(s) to my services so that I can CHOOSE them; added an ACE/ACL to; added incoming/outgoing rules to accomodate traffic to those ports....NOTHING.

Routers / Switches :: Rate Limit On Specific Port From Specific Range?

Jul 1, 2012

Is it possible to enable an absolute value rate limit using QOS on a HP ProCurve 5406 switch for a particular IP range on a specific port? Is there a way to configure our HP 5406 with an absolute rate limit on "WAN" port for that server's IP range? I would like to limit it to only being capable of sending 1Mbps worth of traffic over the head end at once.Everything in the documentation points towards priority queues, which as far as I can tell, isn't really what I want.Baring accomplishing this goal using rate limiting is there a better way to prevent our services from accidentally saturating this connection?i thimkong about somthing like that:

class ipv4 rate-limit-port-A1
match ip 10.136.0.0/16 any
exit
policy qos port-a1-ratelimit
class servers-to-be-slowed action rate-limit kbps 1000
exit
interface A1 service-policy port-a1-ratelimit inI'm not sure about this.

Trying to get a service setup with a third party to access our system (ERP web service to access our ERP data, making data available to customers and vendors via internet).  They require that I setup four external IP addresses to have access through the firewall.  I haven't figured out how to do this. I'm using a Linksys WRV200 router.

Cisco Routers :: RV042 - How To Close All Ports And Leave Some Specific Open

Apr 18, 2012

A company with 20 branches in Rio de Janeiro area. The main servers are in a datacenter located in downtown.Each branch has a RV042 router with firmware version 1.3.12.19-tm (Feb 13 2009 13:03:21) installed.All users in this network have a proxy configuration pointing to proxy.[blah].com.br port 3128.the HTTP/HTTPS traffic should go through proxy only. [code] Some "smart" users were caught using Ultrasurf application, which changes the proxy settings to go through port 9666 or even 443.In other machines, we've found some black proxies [for example: 212.46.27.142 port 8080].
 
My objective:

- To close all ports in Firewall -> Access Rules section and grant permission only to some selected and specified ports.

- To redirect all HTTP/HTTPS connections to go to proxy's IP address only.
 
Which Access Rules can I set in these RV042s in order to block and prevent these users to continue abusing this network?The users who were caught using Ultrasurf were fired.

How do I go about opening specific ports on an E4200?I'm having disconnect issues with a particular game, and the Customer Service drone thinks the ports required for the game aren't open. Nevermind the fact that it's worked fine for 6 months now, and the problem only started a few days ago.I figured I'd humor the idiot and open the ports, but all I can find is information on forwarding, not making sure the ports are open

Apr 20, 2013

open specific ports on 1941w Integrated Services Router.This specific router is a wireless VPN router that has a wired module and a wireless module and VPN so I'm getting 3 subnets on my network - 192.168.1.. for the wired connections, 10.100.1.... for wireless LAN connections and 10.100.2... for VPN remote connections.I know that by default all connected computers can access my Linux server data through telnet so the telnet port is open by default, the problem is that I have some other software licensing system on my Linux box that needs to be accessed through port 27000 and most of my users are using wireless connections and can't access that license because post 27000 is closed.what is the comand to open this post or any other port that I need to be open on the wired module, wireless module and VPN or at least poit me to somewhere where I can find all the commands that I can use for this router?

Cannot Port Forward Or Open Port For Utorrent

Sep 18, 2012

I have only recently noticed a HUGE decrease in my Utorrent speeds, so i thought i would have a gander and lo and behold.apparently the port Utorrent uses wasn't open. Now, i have tried about 10 different port numbers, made sure Utorrent is being accepted by Norton 360 Firewall,followed complicated directions to (i think) foward ports, and also follow directions to open a specific port.Nothing has worked so far, Utorrent still comes back with a port closed error.

Cisco Routers :: RV042 - Using Specific WAN Port For Particular Domain / IP

I have RV042 router which is connected to the internet by both the wan ports and I want to use it as a load balancer so that both of my internet connections can be utilized evenly. But now I have an issue in this scenario as my remote application gets logout whenever the communicating IP address changes. Is there any way out so that I can specify the wan port used for a particular public IP address/domain name?

Cisco Routers :: RV042G - Dedicate WAN Port To Specific LAN IP?

Mar 23, 2013

Each of the 2 WAN ports on my RV042G has its own dedicated public IP address. I would like to set up the router so that all incoming traffic on WAN1 is always routed to a specific server (=LAN IP), and vice versa, that particular server's outgoing. Internet traffic is always sent through WAN1.
 
It has to be controlled by IP address as the system in question is not directly connected to the router, there is a switch in between.

Cisco WAN :: 5505 - Limiting Port 25 Forwarding To Specific IP Subnets

Jan 26, 2013

just getting started with ASA's. I've got my 5505 almost 100% configured but my port 25 forward to my Exchange server. Currently I've got an access list forwarding all traffic that hits the outside interface on port 25 to my Exchange server (access-list outside-in extended permit tcp any object mail-port-25 eq smtp). What I'd like to do now is say that only port 25 traffic from specific IP subnets gets forwarded. I thought I read that there's a couple of way to do this (from the inside interface, from the outside interface).
 
Also, what happens to port 25 hits that don't fall within the range I specify? Do they get a disconnect reply or do they just get ignored (no reply whatsoever)?
 
Edit: ...just to clarify, the allowed IP's I will be entering are the WAN IP's of my AS/AV service.

Cisco Routers :: RV042 - How To Direct Traffic Through Specific Wan Port

Aug 1, 2012

I have an RV042. I understand and have created the services I need. The documentation is just not clear on how to direct traffic for these services to a specific wan port.
 
Can this even be done with this router? If so, the how? Use rate control or priority? Does checking a wan port mean that it will only go through that port?

Cisco Firewall :: 5505 Block Port 80 On A Specific Host In LAN

Apr 22, 2012

I'm using an ASA5505 (8.4(1)) and would like to block port 80 on a specific host in the LAN so machines in other remote LANs connected via VPN can't access this port on the host. Devices in the local LAN should have access to this port on the host. Here are the commands I'm using:
 
-access-list block_port extended deny tcp any host 10.20.10.20 eq 80
-access-list block_port extended permit ip any any
-access-group block_port out interface inside
 
These commands are not working as I would expect them to. When I browse to http://10.20.10.20 from a remote machine over the VPN tunnel I am able to access the host web server.
