I am fairly new to this forum, pretty new to cisco but I know I will get good help from here.
I have 2 pieces of ASA5505 and I want a site to site VPN for my network of two locations.Site A(HQ) and SiteB(branch)
The purpose is to access a server with local ip 10.1.50.201 in HQ from branch.I have two public ip addresses from ISP.
Can someone help me with all the configs that I need to get the VPN up and running.

Hi,
Your post doesnt yet contain all the needed information. (networks, IP addresses, ASA software levels)
Perhaps you can share the current configurations (with changed public IP addresses) with us so we can determine the needed configurations.

I want to erase the above config.I just need someone to send to me a working config.
remote network address: 10.1.51.0 mask 255.0.0.0
someone can mail me a good config: olaibigbami@yahoo.com
ā07-26-2013 09:33 AM
Hi,
That is only one ASAs configuration.
But there are some clear problems there and with what you are asking.
Majority of your configuration are correct but I would suggest correcting the networks and network masks in the configurations. After they are correct there should be no problem forming the L2L VPN connection. Naturally you have to make sure that the remote end doesnt have same problems.

I have factory-default so I can star over again.I'm not good with CLI so i use asdm for setup.
I would not mind if anyone send me a working config of site 2 site VPN on ASA 5505 so i can use.
All i need is for remote network 192.168.1.0/24 to connect to a server in HQ(10.1.50.0)
Other usersin HQ(10.1.50.0) should be able to connect to server- nothing more.
my configs for the two sites are shown below and VPN is not comming up:

Thanks for anticipated response.

Hi,
Both your NAT0 and VPN ACLs are wrong.
Both of your ASAs also have the same LAN network. Above it says HQ is 192.168.1.0/24?
You have to change the other devices LAN network to the correct one. You also have to change the ACLs I mentioned.
HQ
Add the new ones
access-list outside_1_cryptomap extended permit ip 10.1.50.0 255.255.255.0 192.168.1.0 255.255.255.0
access-list inside_nat0_outbound extended permit ip 10.1.50.0 255.255.255.0 192.168.1.0 255.255.255.0
Remove the old ones
no access-list outside_1_cryptomap extended permit ip object-group DM_INLINE_NETWORK_1 object-group DM_INLINE_NETWORK_2
no access-list inside_nat0_outbound extended permit ip object-group DM_INLINE_NETWORK_1 object-group DM_INLINE_NETWORK_2
BRANCH
Add the new ones
access-list outside_1_cryptomap extended permit ip 192.168.1.0 255.255.255.0 10.1.50.0 255.255.255.0
access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0 10.1.50.0 255.255.255.0
Remove the old ones
no access-list outside_1_cryptomap extended permit ip 192.168.1.0 255.255.255.0 object-group DM_INLINE_NETWORK_1
no access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0 object-group DM_INLINE_NETWORK_1
Also it seems that both of your ASAs are using DHCP for their "outside" interface? How are you going to keep the L2L VPN up for the 2 end points if they dont have a static public IP address?
Or does the ISP assing the same public IP address based on the device MAC address?
- Jouni
ā07-30-2013 09:20 AM
Thank you.
I have made the changes you recommended but both ASAs are still not forming VPN connection.
They are both tearing down TCP & UDP connections and translations to & from outside.They are also denying incoming TCP.
The ISP gave me two public ip addresses.My modem is in bridge mode so the modems delivers public ip addresses to my WAN interfaces.
What else could be tearing down connections & translations? Please, help urgently.
ā08-09-2013 03:57 PM
Hello try this , this is detail step by step configuration ,
ā08-09-2013 06:33 PM
Sounds like you need to tell the ASA not to your internal networks that are traversing the VPN tunnel.
There is a Cisco config guide for this.
This is also dependant on which IOS version you are running

You ASDM. Cisco ASA is well known for its ASDM easy to configure everything.
