Solution manager Remote Connection issues

Hi

I'm currently in the process of setting up Solution Manager 7.1 on windows Server 2008r2 using central system.

I did the prerequisite check & the Solman installation and i'm actuallly working on the post-installation steps.

I'm experiencing difficulty with the step : "Configure Remote Connection to SAP".

I followed the informations provided on : http://service.sap.com/remoteconnection

In the technical prerequesite you have to set up a connection to sap support.

So i have to choose a connection type : I selected Internet connection so my first question is : do we need "VPN with SNC" or "VPN OR SNC" ?

I personnaly understood VPN or SNC.

So from here i decided to use SNC.

The first step was to set up & configure the SAProuter. I decided to do it on an another computer on the same domain ( not on the same computer where Solution Manager is installed ) but i'm not sure it is necesary

I assume I can install Saprouter on the same location as the Solution manager? do you recommend it ?

The Basic Functions testing with niping is working.

The next step is : "establish Internet Connections"

So now i can choose between SNC or VPN : my goal is to establish the connection as fast as possible.

I actually don't have a switch available ( i can get one if necesary but time is running ... ) so i'm opting for the SNC solution.

I tryed to get the certificate for the saprouter but i don't have a register SAProuter, but when i opened a customer messager for component XX-SER-NET, SAP answered about the impossibility to access SAP service Backbone with an SNC , saying that i will need to register a VPN site to site connection to SAP => i don't get it .... Can someone explain it to me ?

So please can one of you guru's tell me how to set this remote connection :

-which materials ( server / switch / firewalls ) ?

-where to get the right documentation ?

-What about DMZ ?

-I have a single IP Address is that enough ? ( setting up nat for port 3299 )

- do i have to contact a service provider ?

My idea was initially to set up the SAProuter on the same computer as the SOLMAN setup & use SNC communication to communicate with SAP but it doesn't seems that easy. Do i need separate installation for Saprouter <=> Solution Manager. ?

What's the minimal infrastructure to establish this connection ?

In addition to that, after configuring the SAProuter, i had trouble with the SAPMMC : on my system , on the instance 0 , the process disp+work.EXE won't run ( yellow light )and i can't find where i made a mistake if you have suggestions ...

Really need your help, i'm on a short deadline ... Any help, even incomplete, would be appreciated.

Thanks a lot.

    Hi,

    You can install SAProuter on your solution manager host. For SAProuter you need one additional IP address that will be public IP address that you need to register with SAP. You can open SAP specific port only on to your firewall like 3299 for SAProuter, 3389 for WTS connection etc.

    SAProuter installation on your solution manager host should not have connection to dispatcher. So, if dispatcher is getting down then there should be some other reason for it.

    Thanks

    Sunny

    Thx for the answer.

    I actually managed to register my saprouter with SAP and was granted with CN/OU & connection informations.

    I followed this guide : http://service.sap.com/saprouter-sncdoc with the addition of this guide : http://wiki.sdn.sap.com/wiki/display/Basis/SAProuterviaSNC.

    My first issue : I'm running with a Windows server 2008 r2 enterprise edition 64 bits with a processor Intel Xeon 2.4ghz ( dualcore). so i decided to use the crypto folder "nt-x86_64"

    For the environment variable i set as System variables SECUDIR = C:\usr\sap\saprouter and SNC_LIB = C:\usr\sap\saprouter\nt-x86_64\sapcrypto.dll

    The generation/install of the certificate is alright ( sapgenpse get_my_name -v -n Issuer is OK )

    using the command :saprouter -r -K "p:CN=mycn, OU=myOUnbr, OU=SAProuter, O=SAP, C=DE" i have

    I get the following message : trc file dev_rout

    no ligging active

    _

    Its strange cause it looks like its running but when i check the services running on windows saprouter isn't started .... How to know if SAProuter is running right ?

    If i folow the SAP procedure : Step 3 : test of the ip connection by the customer : SAP Remote Services : technical preparation ( see SAP Note 812386 ) : it's ask in the note to implement note 766505 via SNOTE : i get the following error msg : Error in remote connection to destination SAPOSS : Error when opening an RFC connection ( LB: Hostname or service of the message server unknown#DEST = SA

    What's wrong ?

    If i use T oss1 in parameter => technical setting => i set my saprouter info in SAProuter 1 ( at customer site ) with instance no. 99 and if SAProuter and SAPNet Message Server at SAP i put the following : Name : sapserv2 / IP Address 194.39.131.34 intance no. 99 and message server name oss001/ DB Name 001/ Instance no.01.

    When trying to "Logon to SAPNet" i have an error Unable to connect to SAPNet message server ( default connection will be used ... )

    and followed by the error screen : "partner '80.15.173.168:sapdp99' not reached WSAECONNREFUSED : Connection refused. do you want to see the detailed error description ? "

    Details : module nixxi.cpp / line 3286 / Method : NipConnect2:80.15.173.168:3299 / Return code : -10 / System call : connect / Error No : 10061 / Error Text WSAECONNREFUSED: Connection refused / Counter : 10

    Any idea ?

    when doing niping.exe -c -H /H/mylocalSR/H/194.39.131.34/H/194/39.131.34 i obtain :

    Wed Dec 07 21:20:09 2011

    connect to server o.k

    Wed Dec 07 21:20:09 2011

    send and receive 10 messages (len 1000)

    -


    times -


    avg 122.148 ms

    max 193.731 ms

    min 81.564 ms

    tr 15.990 kB/s

    excluding max and min :

    av2 118.273 ms

    tr2 16.514 kB/s

    Is it the expected output ?

    I've maintained system data in service.sap.com/system-data ( selecting the sap router ) then i tryed to use the SAP service connection, downloaded the .exe but i can't find the stfk.oez. I realized that in my maintain connection screen i have no space for entering any routestring. Seems wrong ?

    Do i have to use the SAO?

    i've made nat redirection from my router as this : from my public ip to my lan ip ( 192.168.x.x) what should i enter in the routestring : /H/public or lan or hostname ?/S/3299 ?

    Hoping you can help me ! ( the goal of all this is to set up RFC connection for postinst step of Solution manager ).
