IPSEC slow speed
(at first, sorry for my bad English) ;-)
I've virtual pfsense 2.2 installed on vmware.
I use 1 pfsense as master firewall.
I connect on this firewall using openvpn.
Then this firewall is connected to 6 others pfsense using ipsec
each time i have :
1 * phase 1
9 * phase 2 for the vlans.
The problems is, the connexion is working perfectly with 4 other pfsense. But with the 2 others I have slow performance on the IPSEC connexions (+- 50 Kbs)
Does anyone have seens this problem?
Thanks for your answer.
Same Phase 1 and phase 2 configs? or different algos? (heavier encryption)
Same internal hardware/switches?
How did you test your throughput?
Enabling MSS clamping (VPN>IPsec, Advanced tab) at 1400 is a good thing to try.
