Hello,

 

i've got following problem with a conniction by ospf:

 

following devices are involved:

 

msw03 (hp 5400zl) -                     msw02 (hp5400zl)                   - Firewall (sonicwall nsa2400)

192.168.99.3/24     - 192.168.99.2/24 + 192.168.253.1/30 - 192.168.253.2/30

 

working:

ping from msw03 to msw02

ping from msw02 to FW

 

notworking:

ping from msw03 to FW

Re: OSPF neighbor not from other neighbor reachable

The FW is the gateway right. Let's see a tracert from msw03 out to the web.
