Cisco Routers :: RV016 Firewall Policies Via Telnet (rules / Chains / Etc)
Nov 3, 2011
I am having some troubles finding information about how to configure firewall policies (rules, chains, etc.) via telnet on a RV016. The reason for that is that i keep getting some log entries "connection refused - policy violation" and "blocked" even with my firewall wide open (only allow rules on all interfaces, SPI and block wan request disabled, multicast and https enabled, etc.... ). Also, with these exact same rules, i can only connect via PPTP with the firewall disabled. The minute i tick the enable option the tunnel never gets to authentication phase. I then started reading OpenRG manual and many things are quite similar, but some other entries are missing from that manual (maybe some changes made by cisco?). I am trying to figure out some service ids, chains (e.g. the rv016 has some rules redirecting to chains 10, 100, 200 but i can not find them anywhere), and so on. I have only one rv016 and about 60 connections to it so i can not experiment that much without having the whole company on my neck with internet problems.

when opening SSH service to a Database Administrator within my LAN, that has a RV016 as the default gateway. So confidence, I just set up a port forwarding in Setup > Forwarding and everything works fine, cool.
However, I do not want this to be a public access, I need a specific firewall rule for a specific external IP address (only the DBA fixed IP Internet might connect to my database server through SSH).
O noticed that when a port forwarding is created within RV016, it bypass the firewall default rules and wide-opens the service (port) to the web. Conceptually, this is correct, as port forwarding is a network translation, but I expected that my firewall had work over this.
My current solution was to create a "Deny from all" rule at port 22 and then create one additional rule that allows traffic from an specific IP at port 22.

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.

I have a problem with firewall rules. If I set some rules for open communication and some for closed, so I cannot reorder from the end to begin.
Last rules are at the end of all. So I can only reorder in one pages.(I have about 33 rules = 3 pages of rules)

I have made a firewall rule that accepts FTP from WAN2 outside to the inside private LAN with IP address specified.But this didn't work.When I added in the forward rules that FTP had to be forwarded to this IP address it worked.I have done some testing but it seems that the firewall rules do not have any priority on the forward rule.If I disable the forward rule i cannot connect with ftp even with a firewall rule made.

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.

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?

We have had our router and remote computers set up with Quick VPN for over a year. We've had our share of problems but have worked around them.
Now, out of the blue, no one can connect to the VPN. I went in to try to do some 'troubleshooting' and the ONLY thing that allows our VPN connection to go through is to completely disable the RV016 firewall. We have too many remote users to actually start and stop the firewall everytime someone needs the VPN connection.

I have a SRP547W that I have configured the following way:
LAN 192.168.15.1/24 VLAN1
LAN 10.10.10.1/24 VLAN10
LAN 10.10.2.1/24 VLAN100
PPPOE ADSL
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
Have I got the Subnet Mask Correct for the Destination IP? Or should it be 255.255.255.0? It doesnt make a difference either way

I have a new (about 4 months old) RV042 V3 4.0.0.07 firmware that I am trying to use in fail over mode. I have a SOHO and I normally use cable Internet connection. It is quite fast (15 megabit), but not super reliable. I have added DSL (3.3 megabit) which is five nines (supposedly) but not so quick.
I have a Westell 7500 wireless DSL modem located in the basement, where the telephone lines enter the building. This gives me a wireless link to the second floor server room through a wireless router that connects to WAN 2 of the RV042. The cable modem is in the server room and connects directly to the WAN 1 of the RV042. The cable works, but when it goes down, the DSL link comes up but does not allow Internet traffic. The RV042 is set up as a Bridge and I have set up port forwarding to get the cable to work and used similar firewall commands to route the traffic if the router switched over. I suspect that the problem is in the port forwarding (port 80) or the firewall rules(which are pretty simple) because everything looks like it switches over, but it just doesn't work on WAN2.

I would like to isolate my wlan from the remaining network but with two exceptions. First it sould be possible to print from all devices in the wlan and second... my notebook should not be isolated
Therefore I did the followning steps:
1. Create vlan
2.Set access rules
Basically I blocked any inter-vlan-routing from the wireless vlan. I allowed all traffic from the wireless address range to the printer's ip address. I allowed all traffic from the notebook's ip address to the private vlan.
3. Set a static DHCP entry for the notebook
4. Set an IP/MAC binding entry for the notebook
For some reason I can reach any ip address from any wireless device.

I face a strange bahavior with my rv220w router : I set up access rules to deny all outbound trafic for a particular IP range. It seems to work fine .... but when I enable content filtering, HTTP access on port 80 works again (and other ports are denied). It seems that activating content filtering makes the router ignore firewall rule.

How do I submit an RFE (Request For Enhancement) to the Cisco SBR team to encourage them to implement the missing support for VLAN to VLAN firewall rules that was available in the RVS4000 (See [URL]) and that was supposedly added to a beta release of the RV220W firmware (See [URL])?

After updating the firmware of my WRVS4400N from V 2.0.1.3 to 2.0.2.1 all traffic was blocked for all machines, even some not included in the list of PCs. As the log was showing that all traffic was blocked by access policies, I disabled the only rule I had (blocking access to some sites to some MAC address list) and everything worked fine.I tried creating a new, simpler rule but after activation it blocked again all traffic for all the LAN.After many trials, I decided to roll back to the previous V2.0.1.3 which solved this problem.

I am trying to create a VPN between an SRP547W and a Cisco IOS router, in this case a UC540.I am running firmware 1.2.4 (003) Jan 11 2012. Now I can do this with an SRP527W and many other routers successfully. Including other IOS routers 1801, 1941 etc.
The issue I have is on the SRP547W I cannot create more than one IPSec Policy through a single IKE policy. I require this to route multiple v lans to our remote site. When I try to add an additional IPSec Policy I am give the error "IKE policy has been used by other IPSec policy"
This is possible to do on the SRP527W with latest firmware. I have tried rolling back to earlier firmware but instead I am given an error about overlap. Latest release note for this firmware suggest this issue was already resolved.

We have an ASA 5525 running version 8.6(1)2 and a 10 MG pipe. I have execs that want to limit bandwidth on users for stuff like youtube, stream media, and downloads. I found the article on ‘Bandwidth Management(Rate Limit) Using QoS Policies’ so it appears our firewall can do what we want. I’m not a cisco person. My knowledge is limited when it comes to configuration – that’s why we have SmartNet.
Can bandwidth be limited on end users and/or can they limit the ‘bandwidth rate limit’ to just youtube, steaming media, and downloads? If so, what should the limit be? and I’m assume this would be for ‘incoming’ traffic only? we’re running into some bandwidth hogs – usually youtube and/or streaming media. We have a Barracuda web filter which we’ve used to block and monitor activity but I simply do not have time to babysit this all day. I should also mention we do have critical data running up and down the pipe; such as credit card processing, DB replication between in house DB and hosted website, TPCx and EDI, FTP, and such that we don’t want restricted.

We have ASA5500's deployed for remote access concentration.We use Cisco IPsec vpn client with a group policy the chacks for Network ICE BlackIce ersonal firewall.The powers-that-be wish to change to McAfee presonal Firewall ok..Now the Group Policy allows you to check for several pre- configured Firewalls, Cisco Integrated, Sygate, Zone Labs etc.So as McAfee are no listed then I am to assume we go for "Custom Firewall" and this is where I am struggling.To configure checking for a Custom Firewall I must have the Vendor ID and the Product ID.McAfee haven't the faintest idea what we're talking about when we ask them for these details.Or is there a way to extract them from the registry of a machine with the McAfee product installed?

I am configuring a 2921 with enhanced security using the CCP. I have found a behavior that seems strange to me and I'm not sure if I'm misunderstanding something or missing a setting. It seems that if I create a firewall rule to "allow" traffic through, that traffic gets dropped, but if I set the action to "Inspect", the traffic comes through fine. I can actually reproduce this at will by setting up a rule from out-zone to self to allow traffic and I cannot telnet into it from an external ip, but if I change that rule to "inspect" i can connect fine (i dont want that rule set up permanently, was just using it to test the firewall).
If I set the allow rule to log, I see the following line in the application security log:
(target:class)-(ccp-zp-out-self:user-fw-ccp) Passing telnet pkt 1.1.1.1:58141 => 2.2.2.2:23 with ip ident 0
(where 1.1.1.1 is the external laptop and 2.2.2.2 is my WAN IP address of the 2921)
So it looks to be passing the traffic, but that traffic is getting dropped somewhere because the connection is unsuccessful.
Is this the expected behavior of "Allow" action? Is there something I can do to make sure "allow" traffic actually gets through?

I have a rv016 that's been in 24x7 operation since I bought it a few years back. It is out of warranty. It is connected to three cable modems on WANs 1-3. Behind it are a bunch of PCs getting IPs via DHCP. There is a gateway to gateway vpn tunnel setup on wan3 to a rv082 at another site. There is a forwarding entry for http to an internal http server. Everything else is pretty much default.
The router is primarily used to aggregate bandwidth for uploading large numbers of photos. The systems behind the router initiate the uploads and the router automatically load balances the outgoing bandwidth.
This was all working fine until just recently. The ISP is Knology who is upgrading each of the 8m/768k cable modems to 25m/5m. They are also moving from DOCSIS 1 to DOCSIS 3. They are currently in the middle of this upgrade and have upgraded the modems to DOCSIS 3 as well as the speeds to 12m/2m. The problem is that the rv016 Network Service Detection, which is set to "Default Gateway" indicates that the modems fail randomly. Usually only one will be failed, but up to two will fail the Network Service Detection simultaneously.
Knology insists that there is nothing wrong with their modems. I have removed a modem from the rv016 when Network Service Detection indicates it is in a failed state and connected it directly to a computer. It will work, but it has a different IP address and default gateway. As soon as I connect it back to the rv016, it works there too, but on the original IP address and gateway. I've only tried this test this twice so far, so it is a bit inconclusive.
Speed tests behind the rv016 are the same as directly connected to one of the cable modems. The router works normally as it has for years. Nothing else is acting funny.
So my question is, is the rv016 failing or is the ISP having problems?

I have hardware version 2 and firmware 3.0.2.01 (latest firmware available for this hardware version I believe) and I cannot get it to email me logs. I have entered my outlook address and our SMTP server.The log says that it's failing each time it attempts. I have scoured the internet and I cannot find a solution that will work for me. I have found some talk of adjusting an MTU setting which is supposed to be located under the firewall / general tab.

this router (RV016v3, Firmware: v4.1.1.01-sp (Dec 6 2011 20:03:18)) in regards to it not properly directing UDP packets out of the right WAN, as per the settings stored in Protocol Binding section of [System Management, Multi-WAN].I use the section to direct all traffic from desktop computers (192.168.5.100 ~ 192.168.5.199) through WAN4, and all VoIP related traffic (192.168.5.200 ~ 192.168.5.239) through WAN2(PPPoE).Everything seems to be working well except for some of the UDP traffic from 192.168.5.200 which is seen in the log going out of WAN4 instead of WAN2.I have even created a new entry for [UDP/5060~5060]->192.168.5.200~192.168.5.200(0.0.0.0~255.255.255.255)WAN2, and placed it at the very top of the list.Here are a few lines that I've observed in the log: (Refreshed the registration of two SIP Trunks configured in our PBX)
Feb 23 18:11:47 2012 Connection Accepted UDP 192.168.5.200:5060->184.72.227.214:5060 on eth4

Feb 23 18:11:46 2012 Connection Accepted UDP 192.168.5.200:5060->50.56.59.168:5060 on ppp2
There are no static routes configured, so i'm baffled by what could cause some of the UDP packets to go through the wrong WAN.All TCP Traffic from 192.168.5.200 is seen going though WAN2 as it should.

Would one of the 'Cisco RV016' work with a switch? I'm planning on running our work network using this device to load balance between 3 WAN connections and would like to keep the upstairs and downstairs computer users separated via a switch.Will the switch affect the load balancing or will the router still be able to detect each individual user and balance the load as seen necessary?

We are deploying a new batch of RV016 with the latest firmware (4.0.4.02). We are using 3 WAN ports for internet access (WAN1, WAN2, WAN3)The WAN ports connects to Cicso 800 series adsl modem with DHCP.The RV016 WAN1 port setting regularly resets to 0.0.0.0 despite that the modem dhcp is still up and running. A cold boot, resets all the configuration and WAN1 port start working againg a new ip.
All three WAN ports are set to automatically obtain ip from the modems.We have tried several modems, and even swap WAN ports, but the error is persistant to WAN1 only.
WAN2 and WAN3 are up and running without any errors. This error is persistant with WAN1 only.We have also configured a manual ip on WAN1, and after a few hours of operation on all 3 ports, traffic on WAN1 comes to a halt.We have the same error on 3 units we received last week.All there modem are configure on different subnets.It does not seems to be a configuration error with the modem as they work perfectly well with the WAN2, WAN3 ports.We also tested a RV016 out of the box using the wizard setup, without any extra setting/configuration, and we got the same error after a few hours of operation.
