VLANs on Cat3550

Cat3550-EMI

------------------------------------------------

CORE#sh ip route

Gateway of last resort is 172.20.5.33 to network 0.0.0.0

C 172.16.0.0/16 is directly connected, Vlan10

C 172.20.0.0/16 is directly connected, Vlan1

S* 0.0.0.0/0 [1/0] via 172.20.5.33

-------------------------------------------------

CORE#sh vlan

VLAN Name Status Ports

---- -------------------------------- --------- -------------------------------

1 default active Fa0/2, Fa0/3, Fa0/4.......

10 Net_172.16.0.0 active Fa0/10

---------------------------------------------------

Clients PCs places on

-Fa0/2 = PC1 ( VLAN1,172.20.11.9, default gateway - 172.20.5.1)

-Fa0/10 = PC2 ( VLAN1,172.16.11.9, default gateway - 172.16.5.1)

- Fa0/3 = Firewall (VLAN1,172.20.5.33-to LAN,default gateway - none; 194.B.C.D-to WAN, default gateway - 194.B.C.1)

-------------------------------------------

#sh run

......

!

interface Vlan1

ip address 172.20.5.1 255.255.0.0

!

interface Vlan10

ip address 172.16.5.1 255.255.0.0

!

--------------------------------------------------

PC1 can ping PC2 and Firewall

PC2 can ping PC1 but can't ping Firewall

=> Firewall is not accessable for computers from diffrent VLANs ( which is not in VLAN1).

How to resolve it?

Re: VLANs on Cat3550

I resolved it

route -p add 172.16.0.0 mask 255.255.0.0 172.20.5.1 metric 1

I added it on Firewall ( for Win2k)
