How to open all ports through a VPN
I'll put up a second exchange server 2010 in a place of DR and a few problems. The two sites are connected by a pair of ASA5510 via the VPN, point-to-point. I want to exclude any possible VPN problems which maybe blocking ports and I wanted to know if there is an easy way to do it and just allow all unrestricted traffic between the two ASAs. I have attached the configs recurees here... Ewing is the main site and DBSi's DR site. I would appreciate help on this one!
Hello
Seems to me at least that they both have "sysopt" configuration which controls the VPN traffic entering the "external" to its default interface
And the default setting is that all traffic entering the ASA via a VPN connection will bypass the ACL attached to the "outside" interface
The command is "vpn sysopt connection permit". By default put in is not indicated when you issue the command 'show sysopt run '. So you can't really see in your running configuration.
Personally, if I don't get something not working after doing the settings, then I trust simply is newspapers that ASA sent to Syslog server or I followed the newspapers in real-time through ASDM.
If that gives no idea of what is the problem, I probably set up a capture on the ASA to confirm that when I see a link that I also see the return of traffic for this connection.
I also use the command of "packet - trace" often enough to verify that the appropriate NAT configuration is applied to the connection that a user tries.
Format of the command would be
entry Packet-trace

Send all traffic through the vpn tunnel
Does anyone know how to send all traffic through the tunnel vpn on both sides? I have a server EZVpn on one side and one EZVpn client on the other. I'm not natting on each side. I use the value default 'tunnelall' for the attributes of group policy. On the client side all traffic, even if not intended for the subnet of the side server, seems to pass through the tunnel. But if I ping the side server, the same rules don't seem to apply. Traffic destined for rates aside customer through the tunnel, but the traffic that is not pumped on the external interface in the clear. That's not cool.
Hello
Clinet traffic to server through tunnel, that's right, right?
Traffic from server to client through tunnel, but the rest of the traffic is not, no?
This works as expected because in ezvpn, politics of "tunnel all ' is for traffic is coming from the client., do not leave the server.
Side server, customer traffic will pass through tunnel, the rest used.

I can't figure out how to open the port of CD.
* Original title: CD player
I can't figure out how to open the port of CD. There are no buttons, and online forums have not helped. Any suggestions?
Of course - just go on this PC (or computer) and r / click on the DVD/CD drive - you should see "eject" as shown below. Usually there will be a button in the center of the disc too... but sometimes well hidden tray! -Ric.

Allowing ports through a VPN tunnel question
I have a VPN tunnel established and I can ping above but my application fails and I think its because I encouraged not 2 ports (ports TCP 19813 and 19814) through. I'm not clear how should I do for allowing these ports through. I need to add a statement to permit to access my list 'sheep' or what I need to add a statement of license to my list of access interface "external"?
Remote users have an IP address of 172.16.5.x 24 and they're trying to connect to users on the 192.168.200.x 24 192.168.201.x 24. I can't do a ping of the 24 192.168.200.x to the 172.16.5.0/24.
The commands below are what I currently have in my PIX.
My current sheep-access list:
IP 192.168.201.0 allow Access-list sheep 255.255.255.0 172.16.5.0 255.255.255.0
IP 192.168.200.0 allow Access-list sheep 255.255.255.0 172.16.5.0 255.255.255.0
My current outside of the access-list interface:
acl_inbound list access permit tcp any host xx.xx.xx.xx eq smtp
acl_inbound list access permit tcp any host xx.xx.xx.xx eq - ica citrix
acl_inbound list access permit tcp any host xx.xx.xx.xx eq www
acl_inbound list access permit tcp any host xx.xx.xx.xx eq www
acl_inbound list access permit tcp any host xx.xx.xx.xx eq www
acl_inbound list access permit tcp any host xx.xx.xx.xx eq 500
acl_inbound esp allowed access list any host xx.xx.xx.xx
acl_inbound list access permit icmp any any echo response
access-list acl_inbound allow icmp all once exceed
acl_inbound list all permitted access all unreachable icmp
acl_inbound list access permit tcp any host xx.xx.xx.xx eq www
acl_inbound list access permit tcp any host xx.xx.xx.xx eq https
first of all, you disable the commnad "sysopt connection permit-ipsec" on the pix? with this enabled command, which is enabled by default, the pix will ignore any ACLs for encrypted traffic. so if you have Hell no this command, then the acl that you applied on the outside int won't make a difference.
However, if "sysopt connection permit-ipsec" is always on, and then all the port/protocol should be allowed.
you said you could do a ping of 192.168.200.0 to 172.16.5.0. How about you 172.16.5.0 to 192.168.200.0 and 192.168.201.0?
also, just wondering if the vpn lan-to-lan or access remote vpn (i.e. using the cisco vpn client).

How to open a port that is closed? Have Vista Home premium 64-bit
I get this message when you try to get to oracle - OEM
"Ip_address here" is not set up to establish a connection on port "5500" with this computer. The ip address is the address of the local host - all on a single pc.It was woprking then I changed my security/antivirus software and the port is closed. I uninstalled the new software and the port is always closed.
Hi Ames66,
It happens more often because the firewall blocks the program and to allow that program to communicate through the firewall, you can usually do that by selecting the program on the Exceptions tab in Windows Firewall.
If you have Windows Firewall on your computer, follow the steps in this link:
Allow a program to communicate through Windows Firewall
Open a port in Windows Firewall
http://Windows.Microsoft.com/en-us/Windows-Vista/open-a-port-in-Windows-Firewall
If you use a third party firewall manually give exception to the program.
Hope the helps of information. Please post back and we do know.

Firewall: How to open a port tcp inside and out on a single line
How can we combine the firewall command to open port 80 to tcp in and tcp out without having to publish twice?
esxcfg-firewall - o 80, tcp, in, web
esxcfg-firewall - o 80, tcp, out, web
N ° because it is a completely different situation.
When you open in port - allow you to access port 80 on the local computer from the network. When you open port - allow you to access port 80 on remote computers from the local computer. Usually there is no need to open the ports both in.

How to open the port 161 on the ASA and Cisco switches for monitoring of BB
Dear all,
I want to install BB to monitor snmptraps suffering of failure.
The newspaper shows BB cannot connect to all ports of the switch 161, and I even can't telnet to 161 XXX_17f for example.
My switches are Cisco C3550, C2950, etc. of the ASA.
Mon 7 Nov 15:43:03 2011 bbnet cannot connect to the server XXX_17f on port 161
Mon 7 Nov 15:43:03 2011 bbnet cannot connect to the server XXX_9f on port 161
Mon 7 Nov 15:43:03 2011 bbnet can't connect to XXX server on port 161
Thank you
Anson
no need to adjust anything in bb-hosts. If you have added setings in bb-hosts, delete them. Also remove associated in bbvar/logs log files. (otherwise, you'll have purple when you delete the SNMP, trap tags bb-hosts)
A column of trap will be that no show until the device sends a trap to BB.

I need to open a month with a value of Excel spreadsheets in a folder. The only way I can understand them open is to open one at a time. My old version of Microsoft has an option 'open all' when I highlighted all the & right click. This is not an option in the 2010 version. I can't imagine that this is not an option in the latest version. Am I missing something?
Open Excel, and then click file and 'open '. Navigate to the folder containing your Excel files, and select all the worksheets, that you want to open. You can drag a rectangle around them, use control + click, or use SHIFT + click to select more than one. And then click Open. It should open all the excel files.

Hello
I am currently looking to browse hundreds of text files my VI to run the VI once and having labview to open each text file in the order numberical that are contained in a single folder.
In general, I ran each file one at a time through the VI, hours to browse all text files. I'm wondering if there is a way I can specify a target folder and then open each text file in the target folder and walked through my VI in numberical order (each file is located in the order that is MM_01, MM_02, MM_03...). Currently I open a file at the same time, through "the spreadsheet read", then the index table, and then run through filters etc to get the data I need. I hope there is a way to do it, because he will save days of work.
Thanks in advance for your help.
