Remote User VPN "error = No route to host"

Hi All, 

 

I setup a remote user vpn on the USG which has been working great until a few days ago, i dont know what has happened but now I get the below in the logs, it says no route to host but im not sure what it means by this? 

 

Mar 16 19:07:21 ubnt pppd[18653]: pppd 2.4.4 started by root, uid 0
Mar 16 19:07:21 ubnt zebra[679]: interface ppp0 index 1390 <POINTOPOINT,NOARP,MULTICAST> added.
Mar 16 19:07:21 ubnt pppd[18653]: Connect: ppp0 <--> /dev/pts/2
Mar 16 19:07:21 ubnt pptpd[18648]: GRE: read(fd=7,buffer=41e540,len=8260) from network failed: status = -1 error = No route to host
Mar 16 19:07:21 ubnt pptpd[18648]: CTRL: GRE read or PTY write failed (gre,pty)=(7,6)
Mar 16 19:07:21 ubnt pppd[18653]: Modem hangup
Mar 16 19:07:21 ubnt pppd[18653]: Connection terminated: no multilink.
Mar 16 19:07:21 ubnt zebra[679]: interface ppp0 index 1390 deleted.
Mar 16 19:07:22 ubnt pptpd[18648]: CTRL: Couldn't write packet to client.
Mar 16 19:07:22 ubnt pptpd[18648]: CTRL: Couldn't write packet to client.

Any assistance wouldbe great, im new to the USG and have to say its not the easiest firewall ive worked with and im used to Cisco ASA and Juniper firewalls...

 

Thanks

Re: Remote User VPN "error = No route to host"

Ok looks like i found the solution. 

 

IP Tables was blocking the GRE connection. 

 

I added the following to the IPTables config: 

-A INPUT -p gre -j ACCEPT
-A OUTPUT -p gre -j ACCEPT
