hello ramanaiah,
yes.. this is possible.. you just need to do use the static command and the required ACL's on the interfaces... ACL's will be required when communication is only between a lower security to a higher security zone..
for eg:
your inside IP - 10.1.1.1
DMZ 1 IP - 192.168.100.1
you can use a free IP on the DMZ 1 segment and use the following command:
static (inside,DMZ1) 192.168.100.100 10.1.1.1 netmask 255.255.255.255
depending on the access, u can allow specific ports using an ACL:
access-list DMZ1 permit tcp any host 192.168.100.100 eq 23
access-group DMZ1 in interface DMZ1
you need to carefully build these commands and keep giving access between the DMZ networks...
Hope this helps.. all the best.. rate replies if found useful..
