Hello everyone,
Now I’d like to share with you how to deal the NAT is not working on NE20E.
The problem is that customer configure NAT like below, but when he try to ping from internal, it can't ping, check the NAT session, find that the NAT is not working.
#
service-location 1
location slot 3
#
service-instance-group Mada
service-location 1
#
nat instance Mada id 1
service-instance-group Mada
nat address-group Mada group-id 1 x.x.x.x x.x.x.y
nat log session enable
#
acl number 3001
rule 5 permit ip
#
interface GigabitEthernet0/3/6
negotiation auto
undo shutdown
ip address y.y.y.2 255.255.255.252
dcn
nat bind acl 3001 instance Mada
#
#
bgp 65100
peer y.y.y.1 as-number 47442
peer y.y.y.y.1 password cipher %^%#yuV/;b"e6<7U/D8FMt.B|n+r/B&n8U/Q{=LMKWKF%^%#
#
ipv4-family unicast
undo synchronization
peer y.y.y.y.1 enable
#
Check the NAT configuration, it is correct;
Check the route and found that the NAT group addresses did not network to the bgp peer, there is no backup route to NAT group address, it lead to the NAT is not working .
After network the x.x.x.x under bgp, it is working fine.
This is what I want to share with you today, thank you!
