Re: Building network-manager-l2tp on Centos 6.9 laptop

A bit of an update: I never got L2TP/IPSec working. I did notice that I was getting different results depending on whether I used: the client office's guest wi-fi network, my mobile hotspot wi-fi network, my home wi-fi. (My home wi-fi giving the best results but still failing.) At some point I was g...

Re: Building network-manager-l2tp on Centos 6.9 laptop

This link is helpful for working out what the MTU should be: https://www.draytek.com/es/faq/faq-connectivity/connectivity.wan/what-mtu-should-i-set-on-my-router/ Except that the ping commands are in Windows syntax. In Linux, -s (not -l) defines packet size, and "don't fragment" is the default option...

Re: Building network-manager-l2tp on Centos 6.9 laptop

Thanks for your help TrevorH. I do seem to be learning new things, if anything. I have worked out how to get debug logs from xl2tpd. If I start it using this command instead of the service xl2tpd start one: xl2tpd -D I get a lot more info: xl2tpd[5147]: get_call: allocating new tunnel for host WORKI...

Re: Building network-manager-l2tp on Centos 6.9 laptop

Ok, I had other work to do, but I'm back at this now. I have on my list of things to do: - when I am at home (and can therefore just plug into the router with a cable) disable NetworkManager and see if I get any success. That is not today unfortunately, but I will try this tomorrow if I get time - g...

Re: Building network-manager-l2tp on Centos 6.9 laptop

Sorry I should have mentioned this morning I've been trying again, this time I have NOT been modprobing pppol2tp, where previously I have been. (I noticed you haven't, and it works for you) I don't know if that is the difference, but now I am getting this kind of input: Jun 29 12:01:50 HOSTNAME xl2t...

Re: Building network-manager-l2tp on Centos 6.9 laptop

Thanks for your message log. What I did notice is that while most of my connection attempts fail, every so often a connection is established. Jun 28 11:11:31 HOSTNAME xl2tpd[3703]: Connecting to host WORKIPADDRESS, port 1701 Jun 28 11:11:31 HOSTNAME xl2tpd[3703]: Connection established to WORKIPADDR...

Re: Building network-manager-l2tp on Centos 6.9 laptop

Ok, so I have run the four commands: service ipsec start service xl2tpd start ipsec auto --up Work xl2tpd-control connect Work The first three are all ok. The fourth just gives me the command prompt without any output. I wait a few seconds, then enter ip a . No ppp0 ip address. The relevant bit of t...

Re: Building network-manager-l2tp on Centos 6.9 laptop

Yes thank you!: I've added rightid=192.168.3.1 to the Work.conf file and I get this output: # ipsec auto --up Work 002 "Work" #1: initiating Main Mode 104 "Work" #1: STATE_MAIN_I1: initiate 003 "Work" #1: received Vendor ID payload [Dead Peer Detection] 003 "Work" #1: received Vendor ID payload [RFC...

Re: Building network-manager-l2tp on Centos 6.9 laptop

Thanks for your suggestion TrevorH. I've made a bit of progress by changing the ike= line. ("man ipsec.conf" came in very handy, as did looking in the profile.cfg produced by the Windows laptop running Draytek SmartVPN when connected) I now get this: # ipsec auto --up Work 002 "Work" #1: initiating ...
