I am trying to configure a MikroTik RB750GR3 to accept VPN connections from my iPhone. I’ve been through plenty of forum posts, and tried various methods of configuring it, but I’ve had no luck so far. One of the better configuration methods I found is the one below. But still my phone says it can’t communicate with the L2TP-VPN server. Any suggestions?
/ip pool
add name=IPSECVPN ranges=192.168.1.10-192.168.1.15
/ppp profile
add change-tcp-mss=yes local-address=192.168.1.1 name=ipsec remote-address=IPSECVPN use-encryption=yes
/ppp secret
add name=user password=pass profile=ipsec
/interface l2tp-server server
set default-profile=ipsec enabled=yes ipsec-secret=secret-pass use-ipsec=yes
/ip ipsec proposal
set [ find default=yes ] enc-algorithms=3des
/ip ipsec peer
add address=0.0.0.0/0 dpd-interval=2s enc-algorithm=3des exchange-mode=main-l2tp generate-policy=port-override secret=secret-pass
