Online Data Exchange With Moderation
May 2, 2012
I'm looking for an online-service, where I can share files. Something like a forum, but not to text, but to share files (mostly MS office files). Main criteria are:
1) Access only by an account created by the admin (--> limited amount of members)
2) possibility of moderation through admin (meaning that I can determine, who can access which folders, who can upload/change/delete files).Something like OLAT, moodle, or blackboard, for those who know, only smaller.Would I need to create something new or is there some service already existent, where I could rent space?

We started out by switching them over from a normal POP server email service through Outlook and getting them onto Charter hosted Exchange. However, after getting them all set up, we had intermittent connection problems keep occurring. Here is what I know so far:
-the problem is with their network for sure
-re-imaged computers and reinstalled office
-any connection to exchange.charter-business.net is intermittent from their location only.
-replaced modem, router, switch
-tried different DNS servers, same problem
-used their DNS servers from another location, no problem connecting
Once we replaced their switch, the problem morphed a bit. Now, one of them can be connected at any given time without having problems. However, when the other tries to connect, they can't get through. E.g, if user #1 closes outlook, user #2 can now connect without problems.

I am trying to issue command "ssh key-exchange group dhgroup14" on several of my ASA firewalls. The key-exchange command is failing on 3 of 4 ASA firewalls. According to Cisco documentation, this command was introducted in 8.4. My ASA's are running version 8.6.1.10, 9.1.1.8, 9.1.1.10 and 9.1.2. The command is available only with 9.1.2.
Example from one my ASA.

All AD users currently have @company1.com.au email addresses.We have just started an off shoot company and would like to setup emails in exchange so that we can automatically assign and manage emails on the same exchange server. so that each user hasWhat is the best way to do this?At the moment, company2.com - company is hosted outside with someone else. Is there a way that he can direct the mail to us so that he hosts the website but we host the email server?

I think that our users are at the largest capacity for attachments, twice in the past week one of our users did not received important emails because of the attachment size limit. The problem is that the sender thinks we got it b/c there is no bounce back and we have no record of the email being sent. my question is how do i increase the attatchment size for incoming emails?

I have a PC on a crowded network that cannot handle much more bandwidth usage.I am now going to have a tons of transferring to do offsite so I added a second internet line just to deal with the influx of file transfers.I tried a dual WAN setup on my router and the performance was not improved (if it was nobody noticed it) so I said forget that idea, I only need to do these massive transfers from 1 PC so I will just add a second NIC to the machine so that the 1st NIC can maintain local network functionality and the 2nd NIC will be just for internet traffic (sending files up/down to offsite location) Essentially I just need NIC1 for handling local network, connecting to exchange etc. and NIC2 to handle files transfes to offsite location through seconday internet line.So now I have a desktop PC with two NICs. One of them built into the board, the other a pci add on nic. they are both 10/100
On nic1, there is a connection to my network 200.200.1.X which is the internal network for Exchange, local files transfers etc. This is the network i have always had connected and I have no problem connecting to my exchange server etc. (my server is providing dns/dhcp/wins/AD/MSE for the entire network)so I installed a secondary NIC and a secondary network line to the NIC2 on the machine.I set it up with an IP, a SN, a gateway and a DNSI removed the gateway from the 1st NIC.SO then I tried adding a gateway to BOTH of the NICs..This allows me to do EVERYTHING I want, however when i go to whatismyip.com and get a result, the IP it is giving me is NOT either of my static IPs (each network has a seperate internet line with a static IP). Not sure where this IP is coming from, but if i tracert google.com it says I am going out through the primary adaptor.The new IP from whatismyip.com makes no sense to me as it is not either of my static IPs, however it is very close.Would this be a situation where my ISP see's I have 2 gateways defined so it generates a 3rd external IP for some reason? Never heard of this but i am no guru.essentially I just need NIC1 for handling local network, connecting to exchange etc. and NIC2 to handle files transfers to offsite location through seconday internet line.

I can connect to Internet perfectly fine. I can even VPN back into my office. However, once connected via VPN and I launch my Outlook Client, I'm not able to connect to get emails. When I run a "netstat -a", I get my "SYN_SENT" to all my office domain controllers and exchange servers.However, if I connected via my Starhub USB Broadband dongle, everything works perfectly fine.What settings do I need to do on my router? I tried port forwarding and application rules but none worked.

I have a problem with Cisco WLC 2106 (SW: 7.0.98.0) and LAP1262. The client roams to new AP, associates with the new AP and authentication (WPA2 with EAP-TLS) runs fine until WPA2 key exchange.
The first WPA2-Key-paket from AP (1 / 4) is sent twice. On a closer look at those packets with Wire shark, i've found out the first is encapsulated into a 11n-frame (A-MSDU). The resent frame isn't. This figure shows the first WPA-Key-packet:
The next figure shows the 2nd key-packet, without 11n-encapsulation: The problem, that occurs a very long roaming-time with about 5 seconds. As you can see on second figure, the second wpa-key is sent 5 seconds after the first.
Some details:
Client: Tablet PC with Intel 6230 agn
Controller: Cisco WLC 2106
AP: LAP 1262
Controller SW: 7.0.98.0
Encryption: WPA2-AES
Authentication: EAP-TLS
This problem occurs just on 5-GHz interface with 40 MHz channel bandwidth.

We have the following setup on our Cisco ASA version 8.6.1 One to one NAT rule from outside to our Exchange 2010 cluster IP address (DAG group). This is working fine for clients on the internet accessing their emails via Exchange using their phones. The ASA has the MAC address of the active node from the cluster but when the cluster failover it cache the IP address and are not updating the new MAC when the cluster failover. So users from the outside are unable to connect to the new node from outside the ASA as the MAC address from the passive node is in the MAC table. The MAC address on all the switches update within 2 seconds on the internal network and users don't notice any outage.

We have a ASA5510 with a webserver in the DMZ network 10.2.2.0/24. We now want this web server to be able to access the Exchange server in the Inside network 10.1.1.0/24. I researched this and it seemed straight forward according the the Cisco document below:
[URL]
I'm looking to do this with smtp so I added these lines to the config:
static (inside,DMZ) 10.2.2.30 10.1.1.11 netmask 255.255.255.255
access-list dmz extended permit tcp host 10.2.2.2 host 10.2.2.30 eq smtp
The configuration line:access-group DMZ in interface DMZ Already existed in the configuration so didn't need to be re-entered.
ASA Version 8.0(4)
!
hostname xxxx
domain-name xxxx.com
enable password xxxxxxxxxxxx encrypted
passwd xxxxxxxxxxxxxx encrypted

Need the clarity on IKE version 1 with aggressive mode, I assume this is used for remote site VPN and not for site to site VPN.
Correct me I am wrong and also share the inputs on this.

since upgrading to 8.4(1) on our ASA 5520 I've had nothing but issues with our email server not being able to send out emails (timeouts,corruption, etc) and tried everything and then it dawned on me to turn off ESMTP inspection on the ASA's.Since I've down that our Exchange server SMTP works perfectly again.Why is it that ESMTP corrupts emails so badly from exchange server? (ours is a 2010 sp1)does anyone actually use ESMTP inspection at all?

I'm hosting my email on an Exchange Server 2003 box and have my laptop (Vista Ultimate 32 bit) setup to connect to the exchange server for my email. This works fine through a LinkSys RV042 in one location and a LinkSys WRT54GC in another, but fails through the DIR-615 B2 (2.24 firmware) at home. I'm guessing it's blocking something needed for the MAPI connection.

Basically the problem that I have is that I have a new Exchange server sitting on 192.168.12.2 IP address and on the router I have this NAT enabled
ip nat inside source static tcp 192.168.12.2 110 212.115.5.5 110 extendable ip nat inside source static tcp 192.168.12.2 25 212.115.5.5 25 extendable
The Exchange can receieve emails but it will not send them. It cannot make connection to any of the smart hosts on port 25 or can't even send mail using DNS. When I run telnet my.smarthost.com 25 it will not connect but if I run that from the router then it connects fine.

I am deploying a Cisco 1841 in place of our basic DSL router.I have an ADSL WIC and FA0/0 connected to our LAN.LAN IP ADDRESS range is 192.168.1. 0/ 24 I have dynamic and static NAT configured. At this point although I have ACL's configured I have NOT implemented them as yet for the following reason. I am unable to recieve inbound SMTP traffic - now know my MX records are correct as this all owrks happily on our basic DSL router. I can send external emails no problem and all internal email works fine. [code] I am in the process of defaulting the router and programming the barbones to get the link working and see if inbound SMTP works then start building the blocks again.

(10.10.10.2) (10.10.10.3)
[BARRACUDA] [Exchange SRV]
Mail Domain: mail.domain.com (205.50.50.50)
Ok so the mail flows to the Barracuda using a static 1:1 NAT configuration and then gets delivered from the Barracuda to the Exchange server. I want to implement active sync (Direct Push) for Windows mobile devices. They need to communicate with mail.domain.com over port 443. The problem is I want mail to continue to flow to the Barracuda, but direct Direct Push traffic to the Exchange server.I cnow I can't implement two 1:1 NAT mappings from the same external hostname to 2 different servers.

We have a ASA 5510 which was running 8.0.2, we recently upgraded it to 8.2.5 and since the upgrade remote users for exchange 2007 are not able to download any large email attachments(over or close to 1MB). This is only happening to Outlook anywhere users or OWA users who are connecting to the exchange server using https(443) externally. If the same users connects internally they do not face any issue. When i check the logs on ASA i am gettings lots of RESET-O and RESET-I entries. Looks like the connection between the client and the server gets reset.

I am trying to port forwarding Exchange 2010 OWA using ASA5505, wherever I used object NAT or Twice NAT it just doesn't work.... here is my config:
access-list outside-access remark "Exchange Server Access Rules"
access-list outside-access extended permit tcp any host <public x.x.x.11> eq smtp
access-list outside-access extended permit tcp any host <public x.x.x.11> eq https
[code]...
note that i use public ip <public x.x.x.9> on the outside interface for PAT, so all hosts in the same private can access internet

Our ASA 5510 has been in place for nearly two years, we never have any issue what so ever with it. All along the ASA has been using the default policy. Lately, we beeen getting email deferred in our Barracuda Spam firewall. Google quickly reveals that ESMTP does not play nice with Barracuda witch i disabled eventhough we haven't had any issue with it before. However, the issue remains, we still getting email deferred in the barracuda.
While doing more troubleshooting on the ASA, I constated when issue the command show local-host + IP of the Barracuda, there is an IP address in outside of the interface that can get up to 96 UDP port 53 connections with the Barracuda, this connection never get lower than 20! However, when checking the default setup for the Barracuda, i have the values below:
Incoming SMTP Timeout: 20
Message per SMTP Session : 8
Maximum SMTP Error SMTP Session: 2
Maximum Connection per Client 30m:40
My question is if that ASA show up to 96 DNS session with an outside host to my barracuda, won't that push the barracuda to play email deferred timeout ? Should I change the barracuda default setting? Or should i change the connections limits for the Barracuda in the ASA?

Since I have installed my new router, a Linksys EA6500, I have many problems to connect to my Exchange Server, which is located in my house, via Wifi. I tried to synchronize my Iphone and my Samsung tablet but it won't work. Most of the times I get the message that the Exchange server cannot be connected. When I turn off my Wifi en connect via my mobile provider I have no problems. When I am on a third party wifi I also can connect my server. Seems my own wifi causes lots of problems.
