I've been trying to ping myself and another computer but it just wont work. I've been able earlier today to ping my own IP, but not my friends. Now my friend can ping me but I cant ping myself nor him. I've tried everything I've found on the internet, disabling my firewall, making hamachi a private network, public network, rearranging network priority, ICMP, disabling NAT, restarting my computer, forwarding ports, reinstalling hamachi, but nothing so far has changed the message I keep getting while trying to ping myself: "Answer from 5.127.xxx.xxx: Target host can not be reached (Operating system is in dutch so I just translated it, I have no idea what the message is on english comps).
If anyone has any suggestions on how to tackle this, please tell me.
Hi, this might be due to windows firewall blocking the ping (ICMP) protocol. I manage to ping windows remote host connected via hamachi by allowing it through the firewall. Following are the steps for windows 7 (should be similar for other windows version):
1. Go to control panel -> windows firewall
2. Add a new inbound rule, select 'custom'
3. Select 'rule applies to all programs'
4. Select protocol type 'ICMPv4'
5. Just accept the default and hit next for remaining settings
Once you have the rule configured, try pinging your remote host again.
I have the same/similar problem. I've been using Hamachi for several years, and just recently I've been unable to ping/RDC or otherwise connect from my work to my home PC. I have 5 machines on the mesh network. It just started out of the blue.
From my home PC, I can ping/browse all other machines except the work PC. From my work PC, I can ping/browse all other machines except the home PC. Only affects the tunnel between work and home PC.
Does not appear to be a firewall rule, because this morning I was successully connected to my home PC from work via Remote Desktop Connection and Hamachi. Later in the morning, it was showing my home PC offline.
No changes have been made to the firewall on either of the affected machines, and it's strange that it worked for a period of time this morning, but now doesn't again.
I have reinstalled Hamachi client on both machines, but it doesn't seem to have made a difference.
Is this a bug in Hamachi? Any help would be appreciated.
Just wanted to chime in, lest this get written off as one guy's problem. I have a very similar situation. Everything was working fine for me with Hamachi, at home and work, for about a year, and then it just stopped working, both between computers in my home and between computers at work and between home and work. I can't swear that no one has changed the work environment, though that seems unlikely, but I know I havent' changed the home environment. Every machine in my 6 machine cluster is affected. By "not working" I mean no ping, not RDP. I also have tried the permissive firewall changes that I've read about online, including turning off Windows Firewall completely, but to no avail.
I am not fully down though. I have a 5 PC mesh and two machines are able to ping and RDC back and forth. The others do not respond to ping or RDC. I really got Hamachi for the RDC vpn and not sharing local resources, so this is a big issue for me.
I will keep following this thread to see if something useful is suggested and/or discovered as the discussion continues.
This wasn't the issue for me, but I wanted to share that since it seemed to help some others. For me, I was running an applicaton called PeerBlock that is used to block unwanted traffic. Clearly, the 25.* range is not in the whitelists that are loaded so it was being blocked. Adding the computers in my mesh has straightened things out. I can now RDC to the system via the Hamachi IP.
Thanks for the advice. I had tried changing the zone on my Win7 PC to no avail. Strangely enough, I have not had the issue since about a week after my last post. No changes on my end. I'm guessing it's a hamachi issue.
