• CS6 on my Mac downloading all programs are indistinct/blurred/pixely

  Hello! I have a problem with downloading programs CS6. I just bought a Mac and got a new serial number for my CS6, etc. and when I downloaded the Mac version - now the programs are all Blur/Blur. They have look very 'pixely' - not just photos etc, but overall the program! What I have to change somewhere or why does look like this?

  Here's a picture to give you an example. If you compare Photoshop with the 'menu' on it, you will see the difference. Pixely, WHY is the program?

  

  Install the updates for the activation of the retina for the PS and AI. Other applications do not support the retina in CS6 and seem simply sweet.

• with 2 levels of firewall VPN remote access

  We have two firewalls of different suppliers, with the first level being a cisco firewall. The Setup is:

  ISP <-->(router) <-->(Cisco Firewall) <-->(another firewall of the seller) <-->LAN internal

  We need to give remote users (with installed VPN clients), internal access to certain resources in the local network.

  My question, where can I configure my IPSec VPN, for best security practice, given that my router, Firewall-1 & Firewall-2, all take care the VPN features.

  I also want to allow remote users (who are they assigned local IP internal IP pool), to allow to specific resources (servers read) & specific ports.

  So can implement an access list, after that the VPN is terminated & users get their local pool IPs?

  Thank you & best regards

  Hello, MD,.

  What is the version of the code that you run on your PIX? If you run version 6.x of the code, then you will not be able to use the vpn-filter command to restrict access to certain IP addresses.

  You should run version 7.x for it where you can specify an ACL to restrict traffic.

  In addition, only some PIX firewalls can be upgraded to version 7.x, please look in the link given below

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_qanda_item09186a00805b87d8.shtml#Q1

  If you can not pass the PIX to version 7.x, then you will need to use another VPN device.

  Hope that answers your questions. Rate this post if it helped.

  See you soon,.

• Traffic Internet PIN for router ACL

  Hello, I create a router-on-a-stick typical configuration where remote locations running IOS Cisco direct Internet traffic out through an IPSec tunnel that ends on an ASA5510. I'm 99% it and can't seem to move between the rays and the Internet. I'm looking for advice on how to configure properly the ACL entering the router WAN interfaces spoke.

  My question is, what I specifically authorize the return of Internet traffic in the router speaks ACL? I was under the impression that what allows the Hub ASA IPSec traffic would include traffic Internet has hairpined through the ASA and I wouldn't need a specific ACL entry to addresses of Internet sources.

  The router has spoken, I work now is a 3620 running IOS 12.3.26. When I configure the ACL entering on the WAN Interface to allow only the esp/isakmp Hub ASA, I'm not able to receive traffic from the Internet. If I remove the inbound ACL everything works fine. Here are the current incoming ACL from the laboratory network router:

  access-list authorized note 130 incoming WAN connections

  Note access-list 130 IPSec

  Note LAN Access - list 130 subnets

  access-list 130 allow ip 192.168.75.0 0.0.0.255 192.168.168.0 0.0.0.255

  access-list 130 allow ip 192.168.50.0 0.0.0.255 192.168.168.0 0.0.0.255

  access-list 130 allow ip 10.199.199.0 0.0.0.255 192.168.168.0 0.0.0.255

  Note access-list 130 HUB ASA

  access-list 130 permit udp host 172.16.1.4 host 172.16.1.21 eq non500-isakmp

  access-list 130 permit udp host 172.16.1.4 host 172.16.1.21 eq isakmp

  access-list 130 allow esp 172.16.1.4 host 172.16.1.21

  access-list 130 allow host 172.16.1.4 ahp 172.16.1.21

  Note access-list 130 NTP to the router

  access-list 130 permit udp host 192.43.244.18 ntp host 172.16.1.21 eq eq ntp

  access-list 130 authorized note ICMP traffic

  access-list 130 permit icmp any echo host 172.16.1.21

  access-list 130 permit icmp any any echo response

  access-list 130 permit icmp any any source-quench

  access-list 130 permit icmp any a package-too-big

  access-list 130 allow icmp all once exceed

  access-list 130 refuse icmp a whole

  access-list 130 authorized note circulation of Managment

  Note 130-list of access allow ssh

  access list 130 permit tcp any any eq 22

  With the list above applied inbound access on my WAN Interface, internal hosts are able to ping Internet addresses (allowing a response to ICMP echo) but cannot browse the Internet.

  Should I enable a firewall on the router policy to allow the return of the Internet traffic? I thought that rule of ESP permits that would cover.

  Any help is appreciated!

  Unless you're running the IOS Firewall feature on your spoke routers then the router is unable to keep the State of outbound connections. So yes, you will need to also allow the traffic unencrypted in your inbound ACLs on the WAN interface because once the traffic is decrypted, it is then checked against the acl on the interface, see this link to order operations.

  http://www.Cisco.com/en/us/Tech/tk648/tk361/technologies_tech_note09186a0080133ddd.shtml

  On ASA/Pix firewalls you can tell the device to check against the acl on the external interface once that traffic has been decrypted with the command "sysopt connection" but I'm not aware of a similar option for IOS.

• Easy VPN client

  Hi, I am building a vpn using an easy VPN server on 8xx adsl router and a remote client using xp pro.

• What is the difference between restricted and unrestricted PIX?

  Please give me information on the above topic.

  Also the answer before my response.

  It depends what platform PIX you what the differences are between restricted and unrestricted. For example, the PIX535 supports up to 10 interfaces on the UR version and only 8 interfaces on the R version

  By comparing the productdescriptions on CCEL you can determine what exact difference you will have on the specific platform. If you tell us you have the platform, we can help you too, of course :-)

• firewalls pix and microsoft exchange

  help required

  I've set up a test network for the practice of sending e-mail messages between

  Send servers in windows 2000 domains different

  (see attachment for the network layout) is what I'm trying to achieve

  to send messages to a user in the field of cyote.com

  ([email protected] / * /) located behind a firewall pix 501 to a user

  the area of acme.com ([email protected] / * /) located behind a pix 515

  network firewall has been implemented so that messages from freds for barney

  are sent to an email server front-end dmz based acme.com

  and are then transmitted by proxy to the backend mail server where is the mailbox of barney

  located where resides on the inside interface of the firewall 515.

  frontend and backend servers are members of the same active directory

  area and therefore, there should be no problem of received messages to the

  front-end server relayed to the back-end server.

  but the problem I had is that it does not work when I send a message

  Fred barney outlook on freds computer (xp-1) tells me that the message

  has been sent but it never happens to the barneys mailbox there is no error message

  Nowhere on sending messages, so I'm not sure that is the problem

  lies with the firewall 501 does not allow messages through or the firewall 515

  not allowing messages through.

  now I just read that there are problems with microsoft exchange

  (in this case the Exchange 2000 with service pack 3 applied) in conjunction

  with cisco firewalls, but my study guide is not very next on

  How to solve.

  so this a cry for I help have been working on it for 2 weeks and have not been

  to fix this anyone know what I should do to firewalls

  to get this working any help will be greatly appreciated.

  PS

  Outlook web app through the front-end server to barneys mailbox works

  fine (if a little slow)

  the pix 501 is running ios 6.3 (4) and the 515 is running ios 7.0 (4)

  Melvyn Brown

  A simple test would be to telnet from fred's PC to the IP address of the intermediate zone "telnet x.x.x.x 25' if that allows you through this part is good. Move to the next piece of the puzzle.

  As shown previously to enter ' no fixup not protocol smtp 25' to the pix.

• The upgrade of the PIX firewall

  I currently have two firewalls Pix 515 (v4.4 and v6.2). I want to update the v4.4, but am unable to download the software from Cisco. Whenever I try to download using the link 'download pix software', it times out.

  I have already set up a tftp server and plan on the use of monitor mode to perform the upgrade. I already did a "write net:" to save the current configuration. " In addition, the original configuration remains intact, or they will be lost after the upgrade.

  Thanks in advance.

  Looks like you may have a problem with the download or the browser proxy. Try another host and/or browser and see if it works better.

  Since the PIX 4.4 software and versions later, you can go directly to any newer version of the software. To preserve your config, but it's always a good idea to back it up before an upgrade as you did. The config in the PIX is actually not get converted when PIX is restarted with the new software - what happens the first time you do a "write mem" under the new software, it is so important to remember to do as part of the upgrade process. You can then check the config freshly recorded against your configuration of backup for all differences. In addition, it is important to check the Release Notes before upgrading, but if you have a config PIX relatively simple it will probably be fine. One thing you want to do is migrate away from lines on access lists. Cisco is a utility that allows to convert them for you, and it does a very good job as long as your config is not too complex, so I might suggest to give it a try and see how it works for you. The downloadable version of this utility must be on the same page as other PIX software download, and there are versions for Windows and Sun Solaris.

  Good luck!

• Need advice choice btw 2 routers for a pix 506

  Hello world. We have a 506th pix we use for firewalls and VPN (access users to home) attached to a Hub to SBS 2000 Server.

  Here's my scenario.

  DSL---> router Netopia---> Cisco Pix506e-->--> SBS200 hubs.

  We are in the process of upgrading from a DSL line to a T1 internet connection, the T1 provider offers the Cisco 1721 router and my Adviser suggested the Cisco 1841. My question is what is the best according to your experience and my script? The T1 provider does not the 1841. Are there limitations with the vs 1721 the 1841? What is the difference BTW the 2 products, and which is the best?

  Thank you for your excellent support.

  Denise

  Hi Denise,

  I would use the PIX VPN endpoint. The 506e can do 16 Mbps 3DES throughput and 30Mbps throughput AES is clearly the best box for work, although he only software-based encryption. You can get a VPN hardware encryption for the 1721 module, but since you already have the PIX, why bother?

  Hope that help - rate pls post if it does.

• Difference between line and liabilities of ips mode

  Hi I'm new to ips. I got a 4215 sensor ips who says she can define control interfaces it is in passive mode, in which it can read packets directed to it by a switch. now since it is an ips when he reads a packet that triggers an alarm and action game goes to zero it will require a pix or a router to block traffic from the attcker or it may hang on its own since it a FPS. I'm not sure about that. can u pls guide me on this. At latest

  concerning

  Assane

  Hi... the main difference is that Supreme or passive mode provides reactive protection. It can be configured to reset the connection to the attacker, IP blocking, and registration of intellectual property, but it cannot stop the initial attack on the objectives. The reason is that packets which he controls have been copied and transmitted by sessions SPAN or promiscuosly listening to traffic on a segment.

  When the sensor is on inline mode, traffic must pass through the interfaces of the probe (pair). Traffic is inspected, tested against the signatures and then if OK, then transmitted to the destination. This approach offers preventive protection because the sensor can stop an attack BEFORE it reaches the target which is something that IDS (passive sensors) can not do

  In summary, I suggest you try to use your sensor in inline mode... It offers not only the same perfect for ID but additional protection against attacks.

  I hope that helps... Please note this!

• Microsoft secondary authority w / Cisco router / PIX 501

• Active FTP problem between Checkpoint and Cisco PIX

  Hello

  I am facing a strange problem.

  Many of our customers have achieved a Checkpoint FW-1/VPN-1 4.1 SP6 (the last before NG). When they try to connect to an FTP server that is located behind a Cisco PIX firewall, they are not able to transfer data: the connection is established, the authentication to follow, but at the stage of the 'LIST' the connection 'freeze' and the user must close the FTP client.

  Users are facing this problem ONLY in Active mode: passive mode works very well. Turn passive mode FTP client isn't acceptable workaround for most of my clients.

  The problem seems to be related only to the firewall Cisco PIX and active FTP.

  Please, what is someone encountered the same problem?

  Could someone give me any help?

  Thank you in advance.

  Paolo

  Yes it is a (global) problem, even with the last checkpoint firewalls. What happens with Active FTP, it's that each command (get, list, etc.) causes another log on the client (source port) to the server on port 21. If you run netstat from the customer you can check this for yourself.

  What normally happens, with HTTP, FTP, telnet, which have are, it's that the client makes a connection to port 21, 23 etc then returns with a port source such as 1936, 1980, 3000, etc..

  Connect problem with statefull firewall is they do not allow multiple sessions control port number on a destination, as well as a source port can be bound to a destination port, in this case, 21 for FTP. I Don t see it changed, an extreme security risk any time soon, since it s, someone else might be hopping session and block this type of traffic, it's what the stateful firewall are all about and FTP servers are problably the machines more pirated on the planet.

  You´ve mentioned the workaround solution, unfortunately that s the only way, change your passive customers, I think that Unix/Linux customers have a problem with this, change your FTP server can also help, there are multiple servers that can be configured to disable Active FTP, I wouldn know exactly, I only network & firewall... maybe someone else can move on this...

• VPN clients cannot access remote sites - PIX, routing problem?

  I have a problem with routing to remote from our company websites when users connect via their VPN client remotely (i.e. for home workers)

  Our headquarters contains a PIX 515E firewall. A number of remote sites to connect (via ADSL) to head office using IPSEC tunnels, ending the PIX.

  Behind the PIX is a router 7206 with connections to the seat of LANs and connections to a number of ISDN connected remote sites. The default route on 7206 points to the PIX from traffic firewall which sits to ADSL connected remote sites through the PIX. Internal traffic for LAN and ISDN connected sites is done via the 7206.

  Very good and works very well.

  When a user connects remotely using their VPN client (connection is interrupted on the PIX) so that they get an IP address from the pool configured on the PIX and they can access resources located on local networks to the office with no problems.

  However, the problem arises when a remote user wants access to a server located in one of the remote sites ADSL connected - it is impossible to access all these sites.

  On the remote site routers, I configured the access lists to allow access from the pool of IP addresses used by the PIX. But it made no difference. I think that the problem may be the routes configured on the PIX itself, but I don't know what is necessary to solve this problem.

  Does anyone have suggestions on what needs to be done to allow access to remote sites for users connected remotely via VPN?

  (Note: I suggested a workaround, users can use a server on LAN headquarters as a "jump point" to connect to remote servers from there)

  with pix v6, no traffic is allowed to redirect to the same interface.

  for example, a remote user initiates an rdp session for one of the barns adsl. PIX decrypts the packet coming from the external interface and looks at the destination. because the destination is one of adsl sites, pix will have to return traffic to the external interface. Unfortunately, pix v6.x has a limitation that would force the pix to drop the packet.

  with the v7, this restriction has been removed with the "same-security-traffic control intra-interface permits".
