Hi Everyone,
I am trying to establish a GRE tunnel between Cisco and Pfsense. Phase 1 and Phase 2 go up however it is unstable, it disconnects from time to time.
On Cisco, the configuration below as follows.
crypto isakmp policy 1
encr aes 256
authentication pre-share
group 5
crypto isakmp key *************** address 0.0.0.0 0.0.0.0
!
!
crypto ipsec transform-set ipsec-vti esp-aes 256 esp-sha-hmac
!
crypto ipsec profile ipsec-vti
set security-association replay window-size 1024
set transform-set ipsec-vti
!
!
interface Tunnel34
ip address 10.255.255.154 255.255.255.252
tunnel source x.x96.242
tunnel destination x.x133.66
tunnel protection ipsec profile ipsec-vti
!
ip route 192.168.1.0 255.255.255.0 Tunnel34
Pfsense settings below
Internet Protocol: IPv4
Interface: WAN
Authentication method: Mutual PSK
Negotiation mode: Main
My identifier: x.x133.66
Peer identifier: x.x96.242
Pre-Shared Key:
Policy Generation: Default
Proposal Checking: Default
Encryption algorithm :AES 256bits
Hash algorithm: SHA
DH key group: 5
Lifetime: 28800
NAT Traversal: Disable
Dead Peer Detection
Enable: 10 seconds, 5 retries
Also, when the connection establishes, I am still unable to reach the LAN portion of each side.
Anyone can help me with this? Or have done it already?
Thanks in Advance.
