Creating New System Entry in SAPGUI 7.10

Question

Brief Description of the problem:
I am unable to create a new system entry in SAPGUI 7.10 Logon Pad. It works fine if you choose "Custom Application Server" as Connection Type but when you choose "Group/Server Selection" instead the Next Button is still grayed out and hence unable to create a system.
Earlier even the Group/Server box never used to get populated but after creating sapmsg.ini, i could go one step further and now I think it looks for some value in Saprouter field in order for the Next button to get activated.
__*What I am Looking for:__*
Can anyone tell me how could I incorporate a saproute.ini, as I not clear on the syntax and I never have to use the sapmsg.ini and saproute.ini in SAPGUI 6.40 for users who are connected to Internal network. so this is something new in SAPGUI 7.10 and I am still clueless on why Internal users have to use saproute.ini.
<route name>=<route>
Here <route> has the following form: /H/<hostname where saprouter is running>/S/<service saprouter is running>
So in the above string, how will I find the service Saprouter is running.
Thanks

Thanks for the response.
It will work if you add "sapmsSID 3600/tcp" to the etc\*Services* file.
In SAPGui 6.40, i used to just have sapms00 3600/tcp and it works.
so in SAPGUI 7.10 looks there is a slight change and need to suffix the SID details also. I still don't find any SAPGui 7.10 documentation regarding the change I did in services file.
Surprisingly SAP support was recomending to add router entry inorder to make it work inspite teling them we don't need to access SAP systems through router since we access them internally. No good support from them and they just jump to conclusions and they keep repeating the same thing over and over again even if you try to make them understand that it's not what you need.
