Fortigate NAT and ACL
hi,
i'm converting cisco ASA NAT and ACL config to FGT.
can someone confirm if items below are correct?
note i also used forticonverter, but it's not 100% accurate so doing this manually by hand.
1. if ACL has "ip" does it mean i allow "ALL_TCP" and "ALL_UDP" on the allowed services?
access-list acl_outside extended permit ip any host 172.16.8.4
2. for static identity NAT, do i use the vip config "arp-reply disable" and "set type load-balance"?
refer to link/recommendation.
these are used to "un-NAT" or exclude NAT for the public IP on the ASA. these are for downstream customer device/CPE configured with pubic IP/WAN.
nat (inside,outside) source static 200.1.1.1 200.1.1.1
edit "nat_vip"
set extip 200.1.1.1
set mappedip 200.1.1.1
set extintf "any"
set arp-reply disable
set type load-balance
3.for DNAT FW policy, do i use "LAN" for source interface and "WAN" for destination interface?
this FW policy worked for me when i had moved an ASA with "twice NAT" config
nat (inside,outside) source static any any destination static obj_outside-ip obj_inside-ip net-to-net
edit DNAT 1
set srcintf "port 2" <<<< INSIDE/LAN
set dstintf "port 1" <<< OUTSIDE/WAN
set srcaddr "all"
set dstaddr "nat_vip"
set service "ALL"
set schedule "always"
set action accept
set nat disable
