Cisco :: Dual ISP On A 5510 With Static Nat To A Mail Server?
Sep 2, 2011Only trying to have the mail server reachable via the secondary ISP link if the primary ISP link goes out. The public MX records with priority markings should make it so any outside hosts tries the first ISP address then the second ISP address if the first is unavailable. I would be using object tracking to control the default gateway in the ASA. I'm just a bit fuzzy on the NAT with a dual ISP config on single box.It shouldn't happen but... if traffic comes in on ISP2 while ISP1 is still up (and the current default gate) that traffic should return out the ISP2 interface (using the ISP2 address and avoiding asymmetric routing) since there already an existing connection present inside the ASA. Any server initiated traffic would still use the current default gateway defined via object tracking on the ASA.

Jul 24, 2011I'am using ASA 5510 and I try to understand how PAT is working.I want to add a Mail Server in the LAN and a webmail using port 3000 on the server. ( webmail must be reachable from the WAN)This is my Configuration :actually LAN users access internet using NAT with one global IP ( 194.x.x.69) which is the ASA WAN interface.
WAN ----- ISP Router ---------- FW ---------- LAN -------- Mail Server + Webmail
| (25) | (3000)
194.x.x.69 192.168.1.254 192.168.1.6
I need to forward port 3000 and port 25 from outside to inside.For example, from the WAN : [URL] must be redirect toward 192.168.1.6:3000 . What is the Correct Configuration ? And what about the Inside/Outside Traffic,Is there any configuration to add ?
Cisco Firewall :: ASA5505 - Configuration To Allow Inbound / Outbound Mail Communications
Dec 26, 2011I’m trying to configure my ASA 5505, in order to allow my inbound and outbound mail communications. Here with this mail I’ve attached a diagram which illustrates my exact network setup along with ip addresses.
In this setup I’ve enabled port forwarding on my ADSL router (port 25 and 110) and configured the ASA accordingly, and my mail server is located inside my network.
My problem is currently I can send mails from my inside network to outside but my not receiving any mails which originate from outside. I’ve attached my current ASA configuration as well,

Cisco WAN :: Get Mail Server On Port 443 From Internal Network
May 24, 2012I write here to see if some kind soul can not solve my problem (which is common to seeso many people around the world). problem: I have a mail server (192.168.1.17) configured static NAT because it is accessible byPublic IP (PPP.PPP.PPP.PPP). Everything works properly from the outside, but if I get my Mail server (on port 443) from the internal network (192.168.1.xxx) there 'verse. This configuration is called Nat inside-to-inside is done by default by some SOHO routers(such as the TPLINK from 25 euros) but Cisco did not succeed. I search on the internet for 2 days without a get nowhere. PS: I have a Cisco 1801 router. (or 1941 as another router).

Mar 14, 2012When I'm pinging my mail server, it gave me different IP's at different times. As the mail server is actually owned by us, I would like to know if that is possible without the IP actually being changed by someone. This is really critical for me.

View 8 Replies View RelatedCisco WAN :: 877 / 2800 - Use Static ADSL As Backup Connection
May 3, 2011We have a few WAN connecting sites to ISP using BGP. we are looking at getting backup link for 1 site.
We have decide to use an IP WAN ADS L link. we will have 877 and 2800 for each link. from understanding, we have a static routing on IPWAN service. means when both BGP WAN and IP WAN connected to the ISP. ISP will use ADSL as primary ignore the BGP link. so other sites will see a BGP route coming from ISP via the ADSL link for this location.
So we have find a manuel solution, leave ADSL unplugged of power but setup same LAN ip address and connect the cable towards the core switch. when WAN link fail, switch on ADSL. So the static route will advertise to the rest of sites.
just want to know is there any auto solution can disable the ADSL link/ ppp link when the 2800/WAN route is up. and enable the ADSL port when the WAN is down. not sure if HSRP/backup interface/tracking will work? and how?
site office switch - > 2800 - > ISP - > ADSL -> ISP
(need this link to be backup and protocol down, so the ISP will not able to connect to this link and advertise as next hop)

Mar 10, 2013Region : Denmark
Model : TL-MR3420
Hardware Version : V2
Firmware Version : 3.13.27 Build 121206 Rel.60215n
I have a TL-MR3420 router placed in a remote location. The internet connection is via 3G, and since the telco is shifting the IP every 24 hours, the router is configured with DDNS from no-ip.org. This is working OK most days, but sometimes the DNS fails to update. To be able to trobleshoot it, I am trying to make my router send a mail with the logfile every hour. This function seems to be easy and out-of-the-box, but it doesn't wiork. Whenever I try to mail the log I get the error message "Fail to Connect the mail server.".
It is not possible to enter another SMTP-port, so I asume the standard port 25 (like this thread). Most ISP-mail services require SSL/TLS and/or use an alternative port, so I have made my own server. This server is visible on the Internet, and I (and others) are able to connect and send mails using smtp on port 25. But, still my remote TL-MR3420 keep saying "Fail to Connect the mail server.". I have tried nearly everything, including disabling authentication and giving the IP-address of the smtp server directly instead of the URL.

Cisco WAN :: 1841 WIC 1 ADSL Configuration
Dec 12, 2011I am configuring a 1841 router for use in small out office. I will use the s0/0/0 for main WAN T1 connection. I then wanted to use the ATM0/1/0 WIC-1-ADSL card as a failover. I am using weighted static routes for failover. Fe0/0 is LAN interface. When I go into SDM and look at the ATM interface it says this configuration is unsupported?
1. Can't I just get a DSL modem and connect it to fe0/1 and not use ATM WIC and use below for failover?
2. If I have to use ATM WIC what needs to be configured for it to work with Att aDSL?
