Remote Desktop and SSH not works after i change our router

irosoft

Hi guys, in our offices, we have a server OPENVpn of configured on a Windows 2000 machine. It is so since about 2005. Over the weekend, our router is dead. It was a linksys RV042 and I replaced by a Cisco small Business RV042. I have taken the configuration of the linksys and I imported in the Cisco. Everything works well except for openVPN. In fact, OpenVpn works well, it's remote desktop and ssh the problem. The remote desktop stop at "configuring remote session ...". I am able to do a ping on my internal addresses without problem. I tried playing with the MTU, but it changed nothing. The most bizarre in all of this is that I have exactly the same configuration as before, nothing has been changed. If you have ideas ...

Thank you

The cisco router is more complex than the one you had. Maybe cisco interfere. try another router.

interesting! the cisco accepted this? how are the ports on the cisco router now configured? what are the mtu sizes?

if the vpn works but SSH/RDP does not then you're looking at an MTU issue in most of the cases. Without config files it is impossible to tell , however.
If you're using UDP mode , try adding

fragment 1000

to see if that helps - you can change the mtu setting on the VPN server but unless you also change the MTU setting of the tap-win32 adapter in windows 2000 itself (using e.g. DRTCP) then the setting is lost. Windows 2000/XP do not allow you to dynamically change the MTU: it's a registry setting + reboot.
