Cisco WAN :: Inbound SMTP To Our Exchange Server Through 1841 Rejected

Jan 10, 2011

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.

Cisco WAN :: 1811 - Restricting SMTP Inbound Traffic

Mar 16, 2012

I use a mail filtering service that delivers mail to me via SMTP on standard port 25 on one of my 5 static external IP's. I wish to restrict this to their IP's only (they have two) and I am unsure on how to do so? As it stands now, anything on the net can talk to my mailserver and my logs are filling quickly with failed attempts as a result. Here's my setup and what I am trying to accomplish:
 
mail filtering service -> my public ip:25 -> internal mailserver at 10.0.10.2:25, deny everything inbound except traffic from the mail filtering service, I am thinking an ACL would fit the bill here, but unsure of how to implement. Router is an 1811 with version 15.1(4)M3 IOS. WAN is on fa0, lan is on fa1.

Cisco Wireless :: WLC4402 / Aironet 1240 AG - Logs Are Rejected Due To Network Policy On NPS Server

May 10, 2012

We are using WLC4402 for our Aironet 1240AG access points.  The clients are connecting to the access points and are authenticating to the RADIUS server.  I am seeing the logs in Server 2008 but they are being rejected due to Network Policy on the NPS server.
 
Where do I see the Authentication Type on the WLC4400 or the 1240's?  In order for the clients (authenticated via Active Directory user) I have to set the Authentication in the NPS Connection Request Policy to "Allow clients to connect without negotiating an authentication method". 
 
I do not have a certificate on the server and my method options are MS-CHAP-v2, MS-CHAP, CHAP, PAP, SPAP, and allow without negotiating.  This RADIUS server was moved from Server 2003 IAS to Server 2008 NPS and there were no issues in Server 2003 IAS.  I have all authentication methods allowed and it still gives me the error below.  Only when I check "Allow clients to connect without negotiating an authentication method" it allows the authentication to proceed. 
 
Client Machine:
    Security ID:   NULL SID    Account Name:  Fully Qualified Account Name:    OS-Version:   
    Called Station Identifier:        00-17-a2-87-54-00: SSID NAME
    Calling Station Identifier:        00-41-96-b6-e3-27
 
NAS:
    NAS IPv4 Address:        192.168.90.24
    NAS IPv6 Address:        -
   [code]...

    Reason:    The user attempted to use an authentication method that is not enabled on the matching network policy.

Cisco Firewall :: ASA5510 / Accessing Exchange Server From DMZ?

Aug 16, 2011

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

Mar 18, 2011

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?

Cisco Routers :: Exchange Server - Port Forwarding On 2811?

Sep 18, 2011

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.

Cisco Wireless :: RV220W / Unable To Connect To Exchange Server With IPhone

Aug 21, 2011

I just recently installed a RV220W at my office and (almost) everything works fine. I have noticed that when my iPhone is connected to the RV220 wi-fi network, I get the message "The connection to the server failed" when checking my email. If I disable the wireless on my iPhone, it connects up to the exchange server perfectly fine so it must be a setting with the wireless somewhere but I cannot find it anywhere.....

D-Link DIR-615 :: Laptop Setup To Connect To Exchange Server For Email

Apr 12, 2009

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.

Cisco :: Configure NAT For Internal SMTP Server In ASA 5520

Sep 21, 2012

I need to configure my ASA 5520 version 7.3 firewall to translate our SMTP server residing in local LAN to use different IP address from the outside interface which is used by all other computers to access Internet. Under NAT section, I have NATted this internal SMTP server with different IP address(eg x.x.x.1) and also translated the remaining IP addresses in the LAN to the outside interface(eg x.x.x.2)

my problem is, Whenever i check the header for message coming from the smtp server it shows that, the SMTP server is also translated by using the same outside interface public ip address(i.e x.x.x.2) which is used by other client machine to access internet instead of the x.x.x.1. How I can get my SMTP server to use separate IP and avoid to be blacklisted by some domain.

Cisco Firewall :: ASA5505 (8.4.2) How To Access Inside SBS-Server On SMTP / RDP

Oct 25, 2011

Using an ASA5505, have 1 static outside address, want to access an inside SBS-Server on SMTP, RDP (3389), HTTPS and port 987
 
Have configured network object nat rules using the asdm, SMTP works (I can telnet to the server on port 25 from outside), however for some reason I can not telnet inside and out on port 25, so outgoing mail does not work. RDP does not seem to work from outside, 987 I havent tested from outside. When I try to create a network object nat rule for https I get this message from the ASA:
 
[OK] object network SBS-HTTPS
 object network SBS-HTTPS
[ERROR] nat (inside,outside) static interface service tcp https https
 NAT unable to reserve ports.

Linksys Wireless Router :: E1500 Won't Allow To Connect To An SMTP Server?

Mar 23, 2013

I have an E1500 N300 Router, I've had it for 3 or 4 weeks now. Ever since I've had it, I can no longer send e-mails out with Eudora nor Outlook.  I've tried using about 3 different SMTP's just to verify that it wasn't a server issue. I tried Port Forwarding in the router settings. I selected SMTP and POP3 and checked Enable on both, then save changes. But they don't appear to be taking, as when I go back in and try to set them again, it let's me and doesn't give me a Port Overlap warning. I've been told that I shouldn't need to mess with Port Forwarding at all, I just need to go into the Firewall settings and open up the SMTP, POP3, and IMAP ports. However, I don't see any settings in my Router settings to allow this, aside from Port Forwarding and it's not actually saving the changes. I will admit, I'm not all that great with this stuff, and this is the first time I've had any issues with a Router stopping me from E-mailing.
