i have 2 sites, site A and B
site B has firewall
site A has multiple VLANs in the network ( say 50,60,70)
from site A i can ping all the networks, ie: netowrk 10 and network 172 on side B and get reply no problem
from site B the only issue with network 172 can ping vlan 50 & 70 on side A but not VLAN 60
so from side A i can ping network 172 on side B and get reply but not vise versa
knowing they all have same rules
