PIX501 vs pcAnyWhere

Hi!

I have i PIX501 with a very basic configuration. But I need some support to open two ports so I can run pcAnywhere through the PIX. Anyone who can help me?

The config looks like this:

Re: PIX501 vs pcAnyWhere

Hi -

You'll need to allow the following on your PIX, use ACLs and not conduits - remember not to mix conduits with ACLs.

> pcanywhere-status UDP 5632

> pcanywhere-data TCP 5631

And also check the following document, check the Port Literal values section:

http://www.cisco.com/en/US/products/sw/secursw/ps2120/products_command_reference_chapter09186a00801727aa.html#45351

Hope this helps and let me know how you get on.

Jay.

Re: PIX501 vs pcAnyWhere

IF he is running a old version of pcanywhere, he might need to check the port numbers - they have changed at least once over the years. He should also check to see if there are any patches for it - it has had a lousy security history. a vpn is recommended

Re: PIX501 vs pcAnyWhere

Hi Jay!

I'm a little bit of a newbie in this subject. :-)

Shall I just pust the two lines at the end of

the config-file and then download them to the PIX?

Can I freely change the portnumbers to something else if I want? Finally, how do I download the file to the pix? Through hyperterminal?

Kind Regards, Jorgen

Re: PIX501 vs pcAnyWhere

Please help me anyone!

I have added the two lines at the bottom of my config-file as below but the pix won't accept the new two lines. How should I write the commands to get the pix to accept them?

Re: PIX501 vs pcAnyWhere

Hello Jorgen,

I will try to help you with this issue. I assume that someone is trying to connect to a system on your inside LAN through pcAnywhere. You can let this connection through by making an access-list to do so.

Use the following commands in the configuration mode.

Access-list outside_access_in permit udp any (systems_ip_address) 255.255.255.255 eq 5632

Access-list outside_access_in permit tcp any (systems_ip_address) 255.255.255.255 eq 5631

Access-list outside_access_in permit icmp any any

Access-list outside_access_in deny ip any any

no conduit permit icmp any any

Then apply the access-list to the outside interface with the following command:

access-group outside_access_in in interface outside

This should do the trick. If not, then you can put on some logging to find out what is holding back the connection.--> -->

In configuration mode enter the commands:

logging on

logging monitor 4

After doiing this you should now see at the console what is blocking the connection.

To set the logging level back use the "logging monitor 0" command.

Please let me know how you are doiing.

kind regards Dirk Smit

Re: PIX501 vs pcAnyWhere

Alternatively, if you configured a VPN, you could use it with any application (including pcAnywhere) to connect from outside without opening those ports.

Re: PIX501 vs pcAnyWhere

Hi Plemieux72!

I can't use a VPN because I havn't got a static IP-address and the client who should connect to me don't want to use VPN because it's very tricky for him to config. But if you want to help me so can you freely post an example for a VPN-config based on my config-file. So can we test that one too.

Kindley Regards, Jorgen

Re: PIX501 vs pcAnyWhere

I don't have a static IP either but still use VPN.

It is tricky and takes some time to learn how to configure, however once all the parts are up and running, it's very easy to connect if you use the Cisco VPN Client.

I registered a domain name and since I don't run my own DNS, I also registered with the dyndns.org service. On one of my internal Windows hosts, I setup one of the dynamic DNS clients listed on that site. The client automatically updates my A record on dyndns.org's servers when my public IP address changes.

So, in the Cisco VPN Client, instead of connecting to a public IP address, I use vpn.xxxxxxxxx.com. The address gets resolved, the security negotiation occurs and voila.

You do need to learn about IKE, SAs, AAA etc. to setup VPN on the PIX. Or, use EasyVPN (I never tried it so I don't know how easy it is).

Re: PIX501 vs pcAnyWhere

Oki, I think I just open up two ports temporary will I use the pcAnywhere software. It's not so often we use pcAnywhere so we can live with that.

Thank you for your time...
