Telnet 1723 port works and i can ping server from sys-net/sys-firewall/proxy-vm But connection can't be established from proxy-vm. Modem hangs if watch journalctl | grep ppptp
[user@sys-net ~]$ lsmod | grep pptp nf_nat_pptp 16384 0 nf_nat_proto_gre 16384 1 nf_nat_pptp nf_conntrack_pptp 16384 1 nf_nat_pptp nf_conntrack_proto_gre 16384 1 nf_conntrack_pptp nf_nat 36864 5 nf_nat_ipv4,xt_nat,nf_nat_pptp,nf_nat_proto_gre,xt_REDIRECT nf_conntrack 163840 11 xt_conntrack,nf_nat,nft_ct,xt_state,nf_conntrack_pptp,ipt_MASQUERADE,nf_nat_ipv4,xt_nat,nf_nat_pptp,nf_conntrack_proto_gre,xt_REDIRECT Can anyone help how to use ppptp in QubesOS ? In 2016 Unman says First you need to allow INBOUND protocol 47: On sys-net: modprobe ip_conntrack_pptp modprobe ip_nat_pptp iptables -I FORWARD -p 47 -s <vpn server> -j ACCEPT On proxyVM: iptables -I INPUT -p 47 -s <vpn server> -j ACCEPT Now, zero the iptables counters, (using -Z), and try to start the vpn. You should see the counters incrementing both in sys-net and on the vpn proxy. If the connection fails look to see if any DROP rules are being triggered. By default PPTP uses tcp port 1723 so you could put in a rule to log that traffic : iptables -I FORWARD -p tcp --dport 1723 -j LOG But it doesnt solve the problem. -- -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
