Can't access unit using EOIP

I have this configuration :
a computer connected to a router connected using EOIP to another router
I have ping from computer A to router B
I have ping from RouterB to computer A

when I try to enter router B from computer A using ssh,winbox,www I get no replay
(option is open )
when I check the firewall I can see computer A is getting into Router B

what could be the problem ?

I forget to wirte that RouterB has a route : 0.0.0.0/0 via 192.168.100.254/24 ether1(192.168.100.1)

so can it be that something in 192.168.100.254 is blocking me?
