PCAnwhere and PIX501 stopped working? 1

[AM123]

Hello.

For some reason, our PC Anywhere access has stopped working.

In PDM it is saying these are unparseable commands.

access-list 101 permit tcp any host 216.126.84.3 eq pcanywhere-data
access-list 101 permit tcp any host 216.126.84.3 eq 5632
access-list 101 permit tcp any host 216.126.84.4 eq 5633
access-list 101 permit tcp any host 216.126.84.4 eq 5634

You're missing your access-group command:
"access-group 101 in interface outside"

-gbiello

 

[AM123]

Thanks that worked amazing.

Two problems though.

When I go to whatsmyip.com, it is coming up as 216.126.-.3 when it is set to 216.126.-.2 in the config.

Also, the Desktop-1 is coming up with an internal IP of 192.168.1.6 for some reason when it was always 192.168.1.5

DO I just need to change this command to 192.168.1.6

name 192.168.1.5 Desktop-1

Thanks for all your help.

Alex

 

[gbiello]

Look at these lines:

name 192.168.1.3 Desktop-2
name 192.168.1.5 Desktop-1
static (inside,outside) 216.126.--.3 Desktop-2 netmask 255.255.255.255 0 0
static (inside,outside) 216.126.--.4 Desktop-1 netmask 255.255.255.255 0 0

Note how the IP addresses don't agree with each other. whatsmyip.com is correct if your browsing from Desktop-2.

[AM123]

How do I fix this. I just want to use PAT and have them all use the same IP and have PCAnywhere redirect the ports to the correct machines.

Funny I told Cisco this is what I wanted to do and that is what they told me to do.

Thanks.

Alex

 

[AM123]

One more thing. I do at a later time (a few weeks) I want to have HTTP, SSL, FTP, NEWS, MAIL all directed to a machine on the inside that uses a couple of the IP Addresses we have. So I do want that option later on.

Thanks.

 

[gbiello]

Here is a sample configuration of how I have redirected pcAnywhere to multiple machines. They all come in to the same address, just on different ports. Keep in mind, you will have to configure the remote pcAnywhere clients with these ports.

access-list outsidein permit tcp any host w.x.y.52 eq 5631
access-list outsidein permit udp any host w.x.y.52 eq 5632
access-list outsidein permit tcp any host w.x.y.52 eq 5633
access-list outsidein permit udp any host w.x.y.52 eq 5634
access-list outsidein permit tcp any host w.x.y.52 eq 5635
access-list outsidein permit udp any host w.x.y.52 eq 5636
static (inside,outside) tcp w.x.y.52 5631 192.168.0.102 5631 netmask 255.255.255.255

static (inside,outside) tcp w.x.y.52 5636 192.168.0.101 5632 netmask 255.255.255.255

hope this helps,

[gbiello]

In those lines, try replacing "216.126.**.2" with "interface"

 

[AM123]

When I try that it spits this back at me:

ERROR: invalid IP address interface

Again, thanks for your help!

Alex

 

[gbiello]

I'm assuming you tried a "access-list pcanyaccess permit tcp any interface eq pcanywhere-data" when you got the error. The interface *should* already by set.

Hmmm. Try a 'clear xlate' first.

I'm going to be on the road for a while, so I won't be able to help for a while. Hopefully this will work.

good luck,
-gbiello

 

[AM123]

Yeah that didn't work. I apprecaite all your help.

If anyone could help me that would be great.

Thanks.

HI.

> How do I fix this. I just want to use PAT and have them all use the same IP and have PCAnywhere redirect the ports to the correct machines

Why? What's wrong with using static mapping for those PCAW workstations. Those workstations will also "go out" to whatismyip using the static mapping, while other will use PAT.

Port redirection is not supported in PDM and I think that in your case it adds complexity without any need.

> If anyone could help me that would be great
Try to post an updated question with current configuration, and information about the current situation.

I thought I saw something in the PDM re: port redirection.

The reason I want to use 1 IP is that I would like to get rid of the other IP's due to the cost of these IP's.

Geez, it was so easy to do this with a DLink firewall (port redirection, that is).

If you could let me know how to do it I would appreciate it.

Can I do this with the tool that is on your website Yizhar.

Thanks
Alex

 

[yizhar]

HI.

> Can I do this with the tool that is on your website Yizhar
No, pixcript does not support port redirection.

You will not be able to redirect the same port on same ip address, to more then one internal host.
So if you have more then a single PCAW inside, you will need at least the same number of registered ip address outside, unless you use VPN to encapsulate the traffic.
So using port redirection instead of "normal" static, will not reserve more then 1 ip address.

[AM123]

I would like to assign differnt ports to different machines:

In PCAnywhere you can assign ports for this exact scenario.

Here are the ports:

access-list pcanyaccess permit tcp any host 216.126.**.2 eq pcanywhere-data
access-list pcanyaccess permit udp any host 216.126.**.2 eq pcanywhere-status
access-list pcanyaccess permit tcp any host 216.126.**.2 eq 5633
access-list pcanyaccess permit udp any host 216.126.**.2 eq 5634
access-list pcanyaccess permit tcp any host 216.126.**.2 eq 5635
access-list pcanyaccess permit udp any host 216.126.**.2 eq 5636

I would like these ports to go to differnt machines. I am positive you can do this with the PIX.

I would like eq 5631 and 5632 to go to 192.168.1.2
I would like eq 5633 and 5634 to go to 192.168.1.6
and
I would like eq 5635 and 5636 to go to 192.168.1.4

Thanks Alex!

 

[yizhar]

HI.

I think that using different ports will work for you.

But since you already have VPDN enabled, you can connect to PCAW over the PPTP tunnel, and in that way you don't need the port redirection nor additional access-list entries.

[AM123]

Is there any documentation on how to do this? How do I direct the External PC ANywhere client to a particular machine? Would each internal machine have to be assigned to a different external IP?

Thanks.
