Hi,

i m confronted to a strange problem using RB 2011 router. I replaced 3 draytek 2830 by 3 brand new mikrotik rb 2011. I connected them to ADSL link and build 3 Ipsec Vpn between them.
I enable dhcp on each RB 2011.

Everything is working fine except:

- on 3 computers i have general failure on ping. on one computer i have those failure with ping on the Domain server and on two others i have general failure on internet public address such 8.8.8.8. The very strange thing is that if disable the RB 2011 DHCP server and I enable The DHCP server on the Draytek, every problems disappear. if i go back on DHCP of the Mikrotik. The problems are coming back immediately.

- I have this second problem: I can't use port 80 or 443 between the routers using the IPSEC VPN. I cant neither use Winbox using the vpn (winbox with public addresss is working fine). I also have occasional problems on Pop3 protocol. Its not that the protocol doest work but it seems to be very slow . I can connect on winbox but all the windows stays empty. The port 80 or 443 stay on "connection" message. The Pop3 give error 0x800CCC0F (outlook) on some computers.

Thanks for any help.

(sorry for my bad english)
