"not sure if this is related or another setup issue also my server keeps rebooting due to a serious errors caused"
--> This is what i would investigate - some of the suggestions below are for the sake of testing if you deem it safe:
1. Do you have more than one firewall installed on that computer? Does disabling it help? Does uninstalling it help?
2. Do you have a networking suite installed? Does disabling it help? Does uninstalling it help?
3. Is your virus scanner scanning the WinGate directory? Is your Virus scanner also a firewall?
4. Are there any obvious problems in your Windows Event viewer?
5. What other stuff do you have in your Programs directory?
6. What is the blue screen of death (bsod) message?
7. Is a *.dmp file created when the bsod occurs?
8. Can you replicate the reboot any way?
9. What Operating System?
10. Is the Windows Firewall disabled in the Windows services? RRAS?
but now when client and server are connected I cannot see any local networks
Generally when you cannot see any of the remote vpns it means either a security suite is doing its job, and hence you need to make an exception in that security suite, or you have conflicts in your Publish Routes; i.e. the subnets are not unique.
