Cisco Routers :: RV 220W - Create Matching Inbound And Outbound Rules

May 15, 2012

RV220W - I'm trying to create a one-to-one NAT connection to a PC on my network. I have 5 static IP's assigned by my ISP. I've gone through the step of 'registering' each IP in turn on the WAN port, and pinging that IP from an external device until it starts to respond, then I set the WAN IP back to the one I want to use to manage the device.
I think what I want to do is simple. I simply want to NAT ALL traffic hitting my 2nd IP address, let's call it (not the real value) to internally. I want ALL ports both UDP and TCP to be forwarded. This Server is then going to be one end of a VPN tunnel going to another site, but I don't want to complicate things with that for now. So I can't even seem to get one-to-one NAT working! I created the one-to-one NAT on the Advanced tab of the firewall and created rules for all ports for UDP and TCP, but I can still never 'see' the internal server from the Internet. Also, the server will not get out to the Internet (can't hit Google, etc).

Cisco Routers :: SRP547W Cannot Create Advanced Firewall Rules

Feb 27, 2012

I have a SRP547W that I have configured the following way:
Software DMZ going to 10.10.10.x and another to 10.10.2.x - this is working OK
I now want to use the Advanced Firewall features to block all ports except those that I need as the software DMZ forwards everything. When I try to create the rules I get "the values are invalid" message no matter what I try.
I want to create explicit allow rules, followed by a deny all rule for each of the IP addresses used for the software DMZ

Cisco Firewall :: ASA 5510 7.2(3) - Inbound And Outbound TCP And UDP Access

Nov 20, 2011

I'm running a Cisco ASA 5510 with version 7.2(3) and I've been tasked with permitting some inbound & outbound TCP & UDP ports to/from a specified address space on the internet. 

In looking at my current ASA config I see other access lists already configured so I'm assuming I can just set up a new access list in similar fashion, but I wanted to verify here first.

Cisco Firewall :: ASA5505 - Configuration To Allow Inbound / Outbound Mail Communications

Dec 26, 2011

I’m trying to configure my ASA 5505, in order to allow my inbound and outbound mail communications. Here with this mail I’ve attached a diagram which illustrates my exact network setup along with ip addresses.

In this setup I’ve enabled port forwarding on my ADSL router (port 25 and 110) and configured the ASA accordingly, and my mail server is located inside my network.

My problem is currently I can send mails from my inside network to outside but my not receiving any mails which originate from outside. I’ve attached my current ASA configuration as well,

Cisco Switching/Routing :: Inbound And Outbound Per Port Bandwidth Limitation 3560

Feb 21, 2013

I'm intending to purchase a switch for work,and I need to limit the bandwidth of one of the ports to 25 Mbit upload and 25 Mbit download (we have 100/100 Mbit connection and the customer is only paying for 25). I been trying to find information on how this could be "properly" done and what kind of switch I need to buy. As far as I have understood, most L2+ switches support outbound rate limiting, but not inbound, and as I only want the customer to have 25 mbit up and down, I need both.
I been looking at a Cisco Catalyst 3560 switch, and I'm first and foremost wondering if I can limit the inbound AND outbound bandwidth on this switch? Perhaps it can even be done on a simpler, cheaper, switch - as I rather not spend more money then necessary?
Lastly, how to do it, limit the inbound and outbound bandwidth on a single port (perhaps on the above mentioned switch, if possible), to 25 Mbit?

Cisco Routers :: RV 220W - Custom Services And QOS

Aug 9, 2012

I have some questions regarding the addition of custom services and their use in QoS for RV routers (I use the RV220W). Suppose I create a custom service as: 
Name: My Service
Port: TCP 60000
1. Does this port number refer to the port number used by my LAN computer or the port number on the other side e.g. some computer on Internet I am using this service to connect to? Some services use the same port number on the side that initiates the service and the receiving end but there are services that use different ports for the initiating and receiving end. So, what is the meaning of the port number when creating a custom service?
LAN Computer : (port TCP 60000) <----> Internet computer : (some TCP port, not necessarily 60000) - or -
LAN Computer : (some TCP port, not necessarily 60000) <----> Internet computer : (TCP port 60000) ?
2. Suppose I create a QOS profile binding configuration with respect to this custom service for a specific IP address on my LAN. QOS is applied to the outgoing network traffic only. How is this profile going to work?
A. Applied to traffic originating from my LAN device with the specified IP address and port TCP 60000 - or -
B. Applied to traffic originating from my LAN device with the specified IP address to another computer's port TCP 60000 ?

Cisco Switching/Routing :: Outbound Versus Inbound Access Lists On Catalyst 3750X?

Mar 17, 2013

I want to configure accesslists on my Catalyst 3750X-switches to protect different VLANs/networks. Any best-practices about inbound versus outbound accesslists? In my head it is more readable and easier to understand the config when accesslists are assigned outbound on the VLAN to protect instead of assigning them inbound on all possible source-VLANs. But of course, from a performance point-of-view it is better to use inbound access-lists to avoid un-necessary routing etc.

Cisco AAA/Identity/Nac :: New ACS 5.4 Install / Can’t Create Rules For Any Policies

Jan 21, 2013

I have a fresh install of an ACS 5.4 virtual  appliance. This ACS instance will only be used for TACACS+ AAA for network  device administration. It is up and running on the network. I have time,  timezone, NTP and DNS configured. ACS admin accounts  and logging are configured. I created an internal user, a network  device, a network device group, an internal identity group, a shell  profile, and command set. It is joined to the Enterprise Active  directory domain, and a couple of AD groups have been selected  for use in policies.The default network device is enabled and  configured with a TACACS secret. I have a lab router configured and  pointed at ACS and I can SSH to it with the ACS internal user.The problem is: I can’t create any rules for any  policies. If I try to add a rule (or edit a default rule) to the “Service Selection Rules” or  “Default Device Admin” or Identity, group mapping or authorization, all I  get is a popup with the message “Resource not  found or Internal  Server error”. If I click “customize” anywhere I  just get empty selection/transfer boxes. If I try to change to a single  result policy from compound rules I get a “System failure – your changes  were not saved” message.  I have installed  this twice now with the same results.This is my first experience with ACS. I’ve gotten  through most of the configuration guide but I don’t know ACS well enough  to know if I’m missing something incredibly obvious, or whether it’s  just broken.

Cisco Routers :: Outbound Nating With RV082?

Jan 9, 2012

I just migrated our office network router to a RV082. While configuring it, I came across three problems: 
(1) From our ISP we have four public IP addresses which I want to make use of for outbound traffic. With the previous router we used we could configure LAN IPs(ranges) to map to static public IPs. Does RV082 support this? I could not find an option for that at the web-interface. From what I understand the 1-1 NATing only goes both incoming and outgoign ways and actually is 1-1 and not the many-to-one I am looking for.
(2) How is it possible to configure incoming port forwards to use a specific WAN interface? Will it always be the primary WAN interface?
(3) Does the telnet access provide more configuration options? I could not log in to it with the same user credentials as with the web-interface.

Cisco Routers :: Default Outbound Policy In RV220W

Aug 1, 2012

How to set the default outbound policy as block in access rules of rv220w? I configure my company router RV220W to block all outbound service traffic, just allow outbound service as : http, https, smtp, dns_tcp / udp. it works fine for some hours, the next day, the rules like expired, the https / smtp / DNS service fail to outgoing, only the http is still ok? What happen? Now I just set the default outbound policy as allow, all traffic can go out, but that is meaningless for a firewall device.

Cisco Routers :: RV180W - Outbound Public IP Address?

Mar 26, 2013

What I'm trying to do seems pretty basic, but I cannot get it working on the RV180?I have 5 Fixed IPs. Using Access Rules I have configured a few inbound rules with specified WAN Destination addresses and these are correctly port forwarding these inbound ports on the specified Public IP addresses. Perfect!
However, for outbound, I need to do the equivalent for one public IP for outgoing SMTP so that our mail servers public facing address is not the standard WAN address and therefore will not fail a reverse DNS lookup. At the moment I have emails bouncing all over the place and panic has set in. I thought the SNAT option was the soltuion, but that just seems to break traffic flow completely on the specified port. I had this working no problem on my old Netgear, but I had to replace it due to throughput limitations.

Cisco Routers :: RV110W Blocks All Inbound Traffic

May 28, 2013

CE IP - /30PE IP - I had configured some floating static route on the PE towards CE .The routes were installed correctly till PE - CE link was UP as next hop IP was showing as connected .Now the link has been removed and I am receiving a supernet of from PE2 via MPBGP. Although the 1st static route for is showing in routing table, the other 2 ( & ) donot show. I believe that as both the routes and next hop fall under the supernet , the static route is not installing. But I don't know why is this behaviour. I tried to remove the distance 250 from both the routes , but still the static route does not install. I tried this on GNS3 but got the same results .

Cisco Routers :: WAN RV180 ALG Blocks Inbound Sip Messages

Sep 4, 2012

I have a sip gateway connect to the LAN side of RV180 router which has ALG enabled.  I have no problem to make and receive calls but sometime I see the router does not forward the 'Bye' message from the VOIP service provider to the sip gateway.


In the capture frame 4292, a 'Bye' message reaches the WAN of RV180 but it never forward the 'Bye' to the sip gateway with internal ip. All settings in RV180 are default with only ALG enabled. I tried to setup Access Rule or Port Forward but none seems to work.  Not sure if they are over-ruled by ALG? With ALG enabled, is it possible to have individual Access Rule?  If there are conflicts between ALG and Access Rule, which has higher priority?

Cisco Routers :: RV110W - Firewall Blocking All Inbound Traffic

I have a RV110W that's been in service since Dec 2012. All Everything is working fine except every month or so the firewall starts blocking all inbound traffic. It does not respond to remote management access. If I reboot the firewall (pwr off/on) everything works correctly for the next month or so and then it begins blocking all inbound traffic again. Local access to the Internet and VPN tunneling are not affected. When it's working, all my rules and port forwarding work correctly.

We are running an RV220W at the latest firmware ( Due to certain internal activity we had to add a few firewall rules. Once we exceeded 10 firewall rules we could not reorder them. The reorder page showed the first 10 rules OK, but when you display the next screen (for rules 11 upward) the order is different and any changes do not appear persistant. Therefore you can change the order of the first 10 rules, but not from 11 onwards.

Cisco Switching/Routing :: How To Setup Traffic Shaping On 4500X Outbound Port To WAN Routers

Mar 26, 2013

We have some ASR WAN routers which have a dedicated 400M interface to a remote site.
Servers on our Local network source the data through some firewalls via 10G interfaces, which connects to 4500X WAN switches then to the Routers on 1G links.
The sources are rate limiting the traffic but the routers are periodically dropping packets which I think is mostly due to burstiness in the traffic between as it traverses through from 10G links to 1G then to 400M. 
How to setup traffic shaping on the 4500X outbound port to our WAN routers.I'd like to see if we could buffer and smoothe out the traffic as it exits the 4500X WAN switch 1G port to the WAN Routers.

Cisco Routers :: RV042 Group VPN And Access Rules

Sep 10, 2012

I've setup a GroupVPN and connect to the RV042 with the Shrewsoft VPN client, works like a charm as opposed to QuickVPN ;-)The firewall is configured with an explicit deny rule for RDP access to an internal server, also an explicit allow rule is created for certain IP numbers as source. I noticed that I need to create an explicit allow rule for the subnet the Shrewsoft client is using for the virtual adapter or I will not be able to access the internal server via RDP through the GroupVPN tunnel.  I would think that setting up a tunnel defies the rules created for direct access on the WAN port.

Cisco Routers :: RV180 Firewall Access Rules And 1:1 NAT

Nov 26, 2012

I have a static IP block and need to route to various servers.  I know I can use 1:1 NAT or Access Rules and have success with each.  The problem is my mail server.  When I use 1:1 NAT, the mail is sent from the correct IP - the address of my mail server - and there is no problem with reverse lookups.  However, I cannot block any ports when I use 1:1 NAT.  I have tried it every way I can think of and even some suggestions in the forums that did not work.  No matter how I set access rules, all port stay open in 1:1 NAT.
If I delete the 1:1 NAT rule and use Access rules to open specific ports, the mail server sends out the mail from the WAN address.  The reverse DNS does not match and mail server will bounce the mail.

Cisco Routers :: RV180 Firewall Access Rules

I purchased a RV180 router, and would like set the Firewall Access Rules as below

- Action: Always Allow
- Service: HTTP
- Source IP: Any
- Send to Local Server (DNAT IP): private ip (192.168.1.xx)
- Use Other WAN IP Address: Enable
- WAN Destination IP: one of public ip (different of the router WAN ip address)
 - Action: Always Allow
- Service: FTP
- Source IP: Any
- Send to Local Server (DNAT IP): private ip (192.168.1.xx)
- Use Other WAN IP Address: Enable
- WAN Destination IP: one of public ip (different of the router WAN ip address)
The firewall access rules no problem within 1 hour after setting. I can access the http / ftp services by the WAN ip address. After several hours, I can't access the services.
I can set the one-to-one NAT rather than use the firewall access rules, but I would like block all other ports, and one-to-one NAT will forward all ports to the private ip address. Administrator > Logging > Firewall Logs , when I enable the settings, where can I get the log of the firewall?
