Hello, I read many pages about setting VPN, but still not properly working... I set up PPTP VPN connection to work right, connect Mac over VPN. Mac is connected properly, IP address is given, but I can't ping any PC in work. My local IP on Mac is: 192.168.1.184, mask: 255.255.255.0, gateway: 126.96.36.199 IP given from remote server over VPN: 192.168.0.23, mask: 255.255.255.0, gateway: 192:168.0.1 Log from Console: Feb 23 12:49:19 s0uky-MacBook-Pro pppd: PPTP connecting to server 'vpn.xxxxx.cz' (188.8.131.52)... Feb 23 12:49:19 s0uky-MacBook-Pro pppd: PPTP connection established. Feb 23 12:49:20 s0uky-MacBook-Pro pppd: pptp_wait_input: Address added. previous interface setting (name: en1, address: 192.168.1.184), current interface setting (name: ppp0, family: PPP, address: 192.168.0.23, subnet: 255.255.255.0, destination: 192.168.0.1). After that I have disconnected internet from Mac and I have connected only over VPN, but if I want use ping, I see this: s0uky-MacBook-Pro:~ s0uky$ ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1): 56 data bytes ping: sendto: No buffer space available Request timeout for icmp_seq 0 ping: sendto: No buffer space available Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 . . .
