I have setup a L2TP VPN Server on my RB2011UAS-2HnD.
When I try to connect from a client I keep seeing the following log entries
Code: Select all
IPSEC: 100 bytes message received from 149.254.181.216(41218) to 86.26.44.192(4500)

IPSEC: 4fd7e881
IPSEC: malformed cookie received or the spi expired.
I have configured the VPN through WINBOX by doing the following.
IP > Pool : Added a Pool "dhcp_pool1" (192.168.88.20-192.168.88.254)
PPP > Profiles > + : Name L2TP VPN, Local Address 10.0.0.9, Remote Address dhcp_pool1, Change TCP MSS yes
PPP > Secrets > + : Name test, Password test, Service l2tp, Profile L2TP VPN
PPP > Interface > L2TP Server : Enabled, MAX MTU 1450, MAX MRU 1450, Default Profile L2TP VPN, All Authentication enabled
IPsec > Peers > + : Address 0.0.0.0/0, Port 500, Auth. Method pre shared key, Secret test, Exchange Mode main l2tp, NAT Traversal on, Proposal Check obey, Hash Algorithm sha1, Encryption 3des, DH Group modp 1024, Generate Policy port override.
Im not sure what step I have missed or gotten wrong. If anyone could provide any assistance, Id be really grateful.
