Cisco Routers :: RV042 V3 - Port Forwarding And Firewall Rules On WAN 2

Oct 13, 2011

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.

Linksys Wired Router :: RV042 Port Forwarding And Firewall Rules?

Oct 31, 2011

I have a system with a RV042 managing the internet connection.Behind the RV042 I have an e-mail server and a development machine that I access through SSH.My problem is that if I forward port 25 to my internal e-mail server it bypasses the firewall rules.I have an external vires and spam scan host that is the only one I should accept incoming email from - but it seems that whenever you add a portforward then it bypasses the firewall rules.

Cisco Routers :: RV042 Port Forwarding Stops Working When Firewall Is Enabled

Jun 4, 2013

I have a RV042 router on a single WAN and an internal LAN. I have configured port forwarding as follows: HTTP[TCP/80~80]->10.0.0.6HTTPS[TCP/443~443]->10.0.0.6IMAP[TCP/143~143]->10.0.0.5IMAP SSL[TCP/993~993]->10.0.0.5SMTP SSL[TCP/587~587]->10.0.0.5
 
Everything works just fine when I have the firewall DISABLED. However, when I enable it the behaviour is erratic. 1 out of 10 attempts to connect to ANY port forwarded works. Almost all attempts time out. Notice that this happens even if using only the default firewall rules (which should be bypassed by the port forwarding as I read in other posts).
 
My second try was to create firewall rules manually, overriding the default ones. I tried adding rules from source WAN1 (where my connection is) to ANY and to SINGLE IP's on every port. Nothing seems to work.
 
I don't know what I'm doing wrong, this is really bugging me. I had to turn the firewall off so we can access our servers from outside the office. This shouldn't have to be done.
 
Just found out that my firewall is getting LOTS and LOTS of Blocked - SYN Flood entries. I think this is why we are having trouble with the firewall. Could this be the problem? I have no idea where all these SYN packets are coming from since they appear with spoofed IPs or come from different bots all over.

Cisco Routers :: Does RV042 Router / Firewall Support Port Forwarding From Internet

Aug 5, 2011

I am using an RV042 router/firewall -- firmware v1.3.13.02-tm -- connected to a cable modem.I have one public address (WAN1) assigned by my ISP's DHCP server.All my machines on the LAN have static IPs.  (RV042 DHCP Server is disabled.)I have set up port (80) forwarding to 192.168.1.101 The HTTP port forwarding does work if an http client on the LAN sends a request to http://<public-ip>:80But I cannot get a response if I send a request to  http://<public-ip>:80 from a machine on the WAN.
 
I  did configure Access Rules to allow http traffic (and then tried to  allow *all* traffic) between a single IP on the WAN and 192.168.1.101 The  incoming log table shows a connection is made from the http client on the internet to the correct http server on the LAN, but there is no resonse  from the LAN to the remote client.Is my configuration the problem, or is this feature not supported by the RV042 router? Could my cable modem be blocking outbound traffic?

Cisco Routers :: RV082 Port Forwarding And Access Rules

Mar 22, 2012

I have found numerous posts discussing this but have yet to find a solution. I have an RV082 with firmware  2.0.0. 2.0.0.19-tm and I need a way to limit the incoming smtp traffic to just the spam filtering company.I have a port forwarding rule to forward WAN1 port 25 traffic to 192.168.1.10.I tried to add an access rule to deny all port 25 and then added one to allow WAN1 port 25 source <spam company> destination 192.168.1.10The RV082 log screen shows the traffic allowed but it does not work. If I uncheck the 'enable' box on the DENY port 25 rule email is still blocked. Only when I uncheck the 'enable' box on the ALLOW rule does email start flowing again.

Cisco Firewall :: ASA 5505 - NAT Rules Set Up For Simple Port Forwarding

Jan 15, 2013

Here is my environment: DSL Modem - ASA 5505 - switch ,Inside network (192.168.2.0/24)
 
What I have successfully done: 
- Modem online and passing on DHCP requests from the ASA to my ISP (ASA does get an internet address on the outside interface)
- ASA assigning DHCP to internal network
- All internal clients can access the internet.
 
What I am getting stuck on is getting NAT rules set up for simple port forwarding. What I would like: ANY internet address be able to access a server on the inside network address (192.168.2.x) over tcp/22 . I set up what I believe to be the correct NAT rule and Access Rule, but the packet tracer fails. Here is my config.  
 
ASA Version 9.1(1)
hostname xxxxxx
domain-name ugh
enable password xxxxx encrypted
xlate per-session deny tcp any4 any4
xlate per-session deny tcp any4 any6

Cisco WAN :: Does The RV016 Port Forwarding Bypass Firewall Default Rules

Jun 20, 2011

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.

Currently I have the RV042 router working in a dual WAN set up, it is configured to accept connections on numbers of ports like 80,443, 25 and forward them to a local ip.

The problem is this only works with WAN1. Is it even possible to forward ports for connections coming in over WAN2?

Cisco Routers :: RV042 V3 And SBS 2003 RWW - Why To Configure For Port Forwarding

Sep 14, 2011

I have tried replacing a loaner RV082 V2 with an RV042 V3 router with firmware 4.0.4.02. All worked well, including the site to site VPN. However, in spite of the fact that I have ports 443 and 4125 forwarded to the server (192.168.2.10), we are unable to connect via RWW. There is no such problem with the RV082. What is different with the way we configure these V3 routers for port forwarding?

Cisco Routers :: RV016 / RV042 / RV082 Internal Port Forwarding?

May 16, 2012

I'd like to setup a WCCP in those routers, but as I read, it's not possible.
 
Another way to circumvent this limitation is to foward a request to the router from the LAN port 80 to a LAN IP, something like:
 
LAN 1 192.168.1.100:80 -> router -> LAN 2 192.168.1.101:80

Cisco Routers :: RV042 Can't Get Forwarding / Firewall And Client To Gateway VPN

Jun 9, 2012

I'm trying to set up a RV042 to do the following:
 
1) Block all WAN connections, except for:

2) Allow all port 80 connections, and forward to 10.4.20.60

3) Allow all port 443 connections, and forward to 10.4.20.60

4) Allow port 22 connections from specific IP addresses, and forward to 10.4.20.60

5) After a remote client has connected using Client to Gateway VPN, allow that remote client to access anything on the LAN
 
I'm able to do #1-4 above, but I can't get #5 to work. Or I can get #5 to work, but can't implement the restrictions I need in #1-4. Attached are some relevant screenshots. I think the problem is that I have Forwarding rules set up that require me to have a firewall rule to Deny All Traffic from WAN1 (unless I'm specifically allowing it). In the Access Rules screenshot, rule #6 is the problem. If I enable it (thereby denying all WAN1 traffic), then VPN clinents can't access anything on the LAN. However if disable this rule, VPN clinents can access anything on the LAN, but the firewall also opens up all outside connections to SSH, since that's set up in the Forwarding rules. I would have thought that once a remote client is connected using client to gateway VPN, then that client is considered to be on the LAN, as far as the firewall is concerned. Thus a firewall rule (like #6) that is specified for WAN1 shouldn't effect remote VPN clients.

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 Firewall :: Change Default SSH Port On ASA 5505 (port Forwarding)

Dec 2, 2011

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?

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

Sep 3, 2012

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?

Cisco Routers :: RV220w Firewall Rules And InterVLan Routing?

Aug 27, 2012

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.

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.
