Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

I work in a hospital. We use the Stratus iPad app for interpretation.  We have a guest internet circuit that these iPads are on.  The circuit was recently upgraded from 35 Mbps to 100 Mbps. No other changes that i know of. Around that time the Stratus app stopped connecting. There is an asa 5505 on this circuit, but only default config is enabled.

 I took the ipad home and the app worked fine on my home wifi.  I ahve contacted the vendor and our ISP. Both claim it must be a firewall issue, but nothing has changed.  Any ideas?

Hello,
I use FreeBSD ipfw, I want to measure current speed in bytes per second and packets per second for monitoring.
If I have a pipe and two queues in it, ipfw doesn't give current speed when executing 'show'. If I try to measure speed by counters (ipfw rules), I don't get real speed because counters measure queue input, some packets can be dropped in queue or pipe.
Please, help.

PFSense v. 2.2.4, connected to a Comcast circuit with 30 down, 15 up.  A computer connected directly to the PFSense tests speeds at right about 30 / 15.  But if a switch is introduced, the speed drops to 2-4 / 10-12.  Several switches have been tried - all 10/100/1000, none managed or manageable.  Several computers have been tried.  Same result with each.  In each case only the testing computer and the PFSense were plugged into the switch - no other devices.  In the PFSense, the LAN interface is set to automatic and shows a connection at 1000 BT, full duplex.  What could possibly be happening that slows the internet down so significantly simply by virtue of introducing a switch?  And it should be noted that upload speeds are still good, it's just download that drops down significantly.   I do realize that the PFSense needs to be updated to a more recent version, and I will do that, but since the speed is just fine when the computer is directly connected I really don't think the version upgrade is the issue.  Any ideas are appreciated!

Many windows 7 workstations on the LAN have full security event logs. The issue is from many netBIOS broadcasts that are being blocked by the Windows firewall and then logged as an Audit Failure.

Why are all workstations broadcasting to each other so much that the logs are filling?
Is the broadcasting normal behavior?
Will it break the network if I disable or block netBIOS from all workstations? I do use the c$ share remotely.
Possibly the firewall shouldn't be blocking this?

Tons of questions because I want to understand this behavior. Thanks!

Hello, I started to configure a PFSense, version 2.4.1. I want to know if it is possible to configure an IPsec multi-WAN failover

Has anyone had any experience configuring this? I already configured the DUAL WAN Failover on the PFSense

I would like that the VPN tunnel can be able to stay up if the WAN fails over.

Thanks in advance

I'm having difficulty finding any decent documentation on the Windows Advanced Firewall predefined rules, and the sets of rules that are created when you select a predefined rule to enable.  Can anyone recommend a decent article, blog, or post that explains what each of these rules do?

Thanks!

Goal: Allow a user to connect to his desktop computer with RDP  ONLY after connecting vpn.

Environment:   OPNsense/Pfsense firewall
53,25,80,443 allow through firewall-
Currently can successfully rdp  with or without VPN with port forwarding - suspect traffic is hitting the fw on public int/public static  and not the desired private Ip a range allocated VPN connection.

User successfully connects to vpn, receives ip, but cant access local resources.
The client side vpn registers an IP address, the FW sees the connection- Just doesn't seem to allow traffic from vpn to local network

The IP range assigned to vpn  connections 10.  the local ip range is 192.

I have a main office running OpenVPN on Untangle v9.4 (I know, but they don't want to spend the money to upgrade and reconnect all of the offices) The remote offices are all on different subnets, and I have no problem reaching the main office by IP address or hostname from the remote office computers. From the main office, I am unable to ping or communicate with any of the remote offices. There are no issues with the main office connecting to the internet, but I am unable to communicate with the connected networks. The OpenVPN connectivity at each office is using a Ubiquiti Edgerouter-X with the config file imported and I use my laptop to support the various offices via a software client OpenVPN connection. When I connect to the OpenVPN server at the main office using my laptop, I am able to ping, use RDP, whatever, I can even use NSLOOKUP from the DC in the main office as the server and get the IP Addresses for the systems in the remote offices. Trying to run a tracert from the cli on the DC server in the main office gives me a first hop that is the LAN address of the Untangle box, but times out on every other hop. This looks like a route issue to me, but I haven't been able to add a static route in any form that allows me to communicate with the remote networks. Help!

Hi,

Enviroment Checkpoint + r77.20

Every time I open a FTP SSL session, IPS drops randomly the transfer. If disabled works fine.

I´ve added  exceptions to IPS  for FTP SSL but still drops sometimes sessions.

For some reason, I can't change the setting of the interface e1 from 100full to auto.
I update the internet speed from 30mbps to 100mbps (Cable provider).
I am not getting 100mbps out from the pix501, if I connect the computer directly to the modem, I can get the 100mbps.

Looking around for a solution, someone recommended to set both interfaces (e0 and e1) to auto. E0 is already set to auto, but e1 I can't change it to auto. The pix 501 give me a message "int e1 can only be set 100full".
Why I can't change it?
Hope someone can help.
thanks for any suggestions to my issue....


PIX Version 6.3(5)
interface ethernet0 auto
interface ethernet1 100full

We currently use OpenVPN, as well as L2TP over IPSec VPN on our Linux servers (CentOS 6.x mostly). Both VPN servers are running properly. However, while each of the physical servers have several IPs assigned to them, the VPN is always able to run on one IP address only.

What we need:

A user connects to our server (either via OpenVPN or via L2TP over IPsec VPN), the server picks a random server IP address instead of just one for all users.

Basically, what we need is a server side IP address rotation for the VPN.

We are looking to confirm some settings on ClearOS 6.9.0 Professional installed on a HP ML310 with multi NIC card installed.

It is currently working fine but the customer site is moving location at the weekend and also changing WAN provider. We currently have the following setup on the ClearOS login from the console (Example IP used)

eth0 external - static - 192.168.14.2 (Link Yes)
eth1 lan - static - 10.7.1.1 (Link Yes)
eth2 external - Static - 10.2.1.3 (Link Yes)
eth3 external - Static 10.3.1.133 (Link No)
eth4 external - Static - 213.100.109.98 (Link Yes)

On eth4 which is physically connected x2 to the router - we can see the following config

Eth4
Role - External
Connection Type - Static
IP Address - 213.100.109.98
Netmask - 255.255.255.248
Gateway - 213.100.109.97

We would like to confirm that
1. The new WAN provider will supply new gateway address (router)
2. We will supply IP address on same LAN as GW address as above
3. SNM will stay the same or as advised by WAN provider

Do we need to change any other networks for the internet route to work? Everything is staying as is, we can see that Eth3 is not connected but do any of the other networks need to know about the changes to the WAN/External change.

We do not have any previous experience with ClearOS, we have used SonicWALL before and presuming that the concept is the same. The CLearOS login on the console does not show an awful lot, neither does the CLI.

Any suggestions from ClearOS…

Recently we added a new TPG IPVPN Connection (MPLS Network with Hosted Firewall) to eth2 on our watchguard but cant get it to work properly (see attached picture)

For some reason i cannot ping any Sydney LAN IP Addresses (on 10.50.2.0/24 network) from QLD Office to Sydney Office.

What do i need to enable / configure on the wathguard so i can ping internal lan addresses from qld office ?

QLD Office LAN is on 10.4.26.0/24 network.
Sydney office LAN is on 10.50.2.0/24 network

From QLD office I can ping 210.10.228.14,210.10.228.13, 10.252.0.6, 10.252.0.5 OK, but if I try to ping the Watchguard LAN IP Address 10.50.2.90 or another device in the same Sydney network from QLD Office it times out. Any ideas ???

Sydney Office Watchguard Configuration is as follows:

I have 3 interfaces setup on my Watchguard x750e firewall with following parameters:

Eth0: IP: 210.10.228.14 (External) - This is connected to a ISP Managed Cisco 1900 Series Router. This is a routed subnet services TPG NBN Conneciton.
Gateway: 210.10.228.13
NetMask:255.255.255.252

Eth1: IP: 10.50.2.90 (Trusted)
Netmask: 255.255.255.0

Eth2: IP: 10.252.0.6 (External) - This is connected to a TPG NTU and is a IPVPN Connection. This also requires RIPv2 and has dynamic routing setup.
Gateway: 10.252.0.5
Netmask: 255.255.255.252
Dynamic Routing Configuration:
1. Enabled Dynamic Routing is enabled.
