someone at work sent me an e-mail they claim was forwarded. I don't think it was, and I need to know before I ask, because accusing someone of making it look forwarded, I viewed the source code, but I can't tell, it was sent through a microsoft exchange server.I think they copied and pasted and changed dates, is there anyway to tell from the source code?

View 3 Replies View RelatedI have a network with the following structure
internet ---- cisco2911 ----cisco3750 --- internal lan
I have two email servers on different vlan
192.168.0.1 ----- 1.1.1.2 (public ip)
10.1.1.65 ---- 1.1.1.3 (public ip)
Before these servers were directly connected to the internet with two nics (Nightmare, I know). The Public IP on internet facing NIC and private ip on LAN facing nic. I'm in the process of changing this.I'm able to access internet from my vlans and also able to send emails but cannot receive emails on these servers.
My router congif is as follows:
Building configuration...
Current configuration : 6234 bytes

I have a issue that i am at a loss as how to solve it. I have an ASA 5505 as my firewall. I have users from other companies who visit from time to time and are unable to use their outlook email to send messages. They can however receive messages without a problem. I also have a situation where users who use windows live to access gmail are unable to send messages.
I have narrowed it down to the fact that these uses are using ssl/tls to send the mails. I did some research and found out about the inspect esmtp setting in the ASA. I have disabled it and i still have to problem. I have also removed all outbound deny statements and still no luck.
Of note is that i can send emails without attachments. They take a long time to go out ( from minutes to hours) but eventually they do. Emails with attachments of even 10k do not go at all.
I was running image 8.2.3 and i downgraded to 8.0.5...still did not work...i upgraded to 8.4.3...still did not work. I am now back at 8.2.3.
My Firewall config is attached. I am at my wits end as to what else to try. The company has not renewed support for the device so i am on my own here!
I have a question about NAT behavior on FWSM 4.0. The problem is email server (Company A) cannot connect to email gateway (Company B) on the outside network and it randomly happen. I got this error from server guy "Detail: xlate has blocked the connection between A’s mail gateway and B’s mail gateway". It work fine again after clear xlate on firewall. [code]
1. How FWSM create xlate table like that? I mean it look like NAT0 for 158.137.21.26 but it doesn't has any nat rule for 158.137.21.26 on firewall.
2. What does it mean "connections 24" at the first of line? In the normal time, I only see the connections is 0 like the second line of xlate
3. After clear xlate global 158.137.21.26, the first line of xlate table is gone then email server can connect each other. Does is a bug on FWSM? or This is a normal NAT behavior of FWSM.

View 1 Replies View RelatedI attached a really ugly picture of how the switches are connected. Basically, we have 4 VLANs in the company. Everything works fine on all VLANs, except the management VLAN (ID 1 - yeah, also the default VLAN ID, I know it's bad and it's going to change some day but...one step at a time). All the switches have their management interface on VLAN1.Here's what works and what doesn't work:If I connect my PC, on VLAN1, to switch number 5 (or any other one on the same row with it) or 4, I can ping 5 (and the entire row), 4 and 3. I cannot however ping 1 and 2If I connect my PC on VLAN1 to switch number 3 I can only ping 1,2 and 3.So basically from what I can gather, switch number 3 (D-Link) is not forwarding VLAN frames containing the tag 1 from and towards the trunk between it and switch number 4 (Cisco).What is strange is that this only happens on VLAN1, everything works perfectly on the others. And it stopped working when we installed the D-Link, we didn't have any problems when instead of the D-Link we had a 48-port netgear switch.

View 4 Replies View RelatedI'm working on setting up a site-to-site VPN connection that requires us to NAT an internal address. Typically, this would be no big deal, but for some reason, it's not working for us. The remote site is reporting that they are seeing the original IP address and not the mapped address coming across. I've monitored the connection and base on our ASA logs, I too see the un-mapped address.
Is there a quick and easy way of verifying that NAT is working? Logs, etc.?
Unfortunately I don't currently have the remote side's configuration, as they are an external business, but I can provide ours: [code]
Based on the above, it sounds as if our configs aren't jibing, which I would think could be caused by the NAT configuration not working, right? I mean if the VPN applicance on the remote end is expecting a NAT-ed address of 12.131.67.247 and they are receiving 12.10.127.108, that could cause this issue, couldn't it?

View 1 Replies View RelatedI used the wlc 5508 GUI to enable multicast in the CONTROLLER section, AP Multicast mode "Multicast" with a group address 239.1.1.1. Also in the "Multicast" section enabled Global Multicast Mode and IGMP Snooping.
My wired network is using a bsr and pim sparse-mode all around. My wlc is connected to a core 6513 L3 switch and on a neighbor L3 switch I can see a shared tree mroute entry and a source based entry for the wlc multicast group I created,
sh ip mroute
( *, 239.1.1.1 )
( 192.168.0.1, 239.1.1.1 )
I can't ping 239.1.1.1 though from anywhere, even the wlc's gui using the ping tool.I can do an ip igmp join on a loopback and ping from a neighbor device and get a reply.
In the monitor multicast section of the gui I can see some Layer2 MGID entries and one in the Layer3 MGID section but not for the 239.1.1.1 address.How do I verify my multicast over wireless setup is working correctly?
I have my 2Wire AT&T U-Verse router properly set up to forward the port 25565 from my machine. (Incidentally, PortForward.com gives me a blank page when I try to look up how to do this.) However, when I test the port is indeed open ( Open Port Check Tool - Test Port Forwarding on Your Router ), it returns as closed. Yes, I'm running the server software while I run the test. I only have the Windows Firewall, but I ran attempts while the firewall was completely disabled as well as with just the appropriate programs allowed.

View 1 Replies View RelatedI have been using Linksys routers for quite some time now, and recently made a big upgrade from the WRT54G to the E3000. I am familiar with the 192.168.1.1 interface and its functionality. However, I recently noticed a problem: when I set a port to forward traffic to any IP address on my network and then check whether or not it is actually open (url...), I am told that the port is still closed. More interestingly still, the first port that I forwarded when I first got the router is listed as open, but the other half dozen or so are still considered closed. I have been trying to set up a file transfer protocol (FTP) server, but can't even get traffic to forward from port 21! I even tried using the pre-configured FTP drop down on the Applications & Gaming tab, but to no avail. Has anyone had similar issues, or perhaps an idea as to why only one port is forwarded when I have followed the same steps that I have been using for years?
I tried to get in touch with Technical Support about this issue, but was told that I needed to purchase a $30 subscription in order to qualify for assistance. I don't think that I should have to pay $30 to know why the same steps work with some ports but not with others.
I have a domain name which I register to my WAN address so I can do service hosting from my home network. I recently switched out my WRT54G running DDWRT with an EA2700. I set up my port forwards and static dhcp assignments and they are working from outside my network, but when I try any network operation involving my WAN address from my LAN machines, the connections just timeout.
I read in some posts that "you cannot do this" and "you have to test from a remote internet machine". Well, this WORKED with DDWRT, so it's not like it's impossible to make a router that does this. Why can't I do this with the EA2700? Is there some magic setting that will let this work??
The whole point of using a domain name is that I can access my services ANYWHERE using the convenient "name" thing.. genius, right? Except when I bring my laptop home and suddenly my domain goes non-responsive.
We have a pair of CSS 11501,Currently it is using source ip for load balancing and 5 servers as backend , however we have users loggin in using http and based on its source IP (ISP PROXY) , it is forwarded to SERVER A.However, we have a SSL page and when the client switches over to SSL , it is forwarded to SERVER B/C/D/E based on its source IP ( REAL CLIENT IP) .This will cause the user to be terminated as the 5 servers are independent and not running in a cluster.
Is there any way that we can use the X-Forwarded-For address to load balance so that when users loging , they are sent to SERVER A (Based on X-Forwarded-For Header IP which translate to REAL CLIENT IP).This way we are able to also send it back to the same server when it uses SSL.I believe that we should be able to load balance using X-Forwarded-For IP or to rewrite the X-Forwarded-For IP into client source IP.
