We have 2 zeroshell boxes 1 at the datacenter and the 2 at our offices .
we have 6 3g modems dongles which we are trying to connect with VPN to our zeroshell machine at our datacenter ( LAN TO LAN VPN ) than bond the connections to have better uplink over the UDP tunnel.
the thing is we have succeeded to connect 3 modems ( 3 vpn’s each vpn has static route thru the usb modems to static ip address at our datacenter ).
now to the problem :
when we connect the 4 vpn after the vpn is up in the BOND the vpn disconnects and we get write UDPv4 : No buffer space available code=105) .
now after a short research we understand that it might be a memory issue but when we run free we see that only 15% of the memory is used .
can you please advise .
