procurve 1910 Vlan routing : no internet access

[SamyFR]

Vlan routing : can't access internet.

Hi ,

I need some help on this issue that is making me mad …

On my switch 1910-8G , I can create VLANs and make routing between them . Each PC in a vlan can ping another PC in another vlan

But a PC in a Vlan can't go on the internet excepting PC in default Vlan

Here is the details :

Switch HP 1910-8G JG348A , version 5,20 release : 1513P99 BootRom 173

Network schema :

Internet Box access : Lan 192,168,1,254 /255,255,255,0 , WAN Fix IP by Internet provider

|

Router : Lan : 192.168.0.254/255.255.255.0 , Wan 192.168.1.253/255.255.255.0 gw 192.168.1.254 on port 8 of the switch default vlan 1

|

|

Switch configured with network wizard : I give it : 192.168.0.253 / 255.255.255.0 and gw : 192.168.0.254

so it create a default IP V4 route : 0.0.0.0 / 0.0.0.0 / Nexthop192.168.0.254 Vlan Interfave 1

I created VLAN 30 and make untagged member Port 3 , and not member from VLAN 1

I created VLAN 40 and make untagged member Port 4 , and not member from VLAN 1

I create virtual vlan interface 30 : 192.168.30.254/255.255.255.0

I create virtual vlan interface 40 : 192.168.40.254/255.255.255.0

PC0 : 192.168.0.11/255.255.255.0 gw 192.168.0.253 on port 1 PVID 1

PC30 : 192.168.30.11/255.255.255.0 gw 192.168.30.254 on port 3 PVID 30

PC40 : 192.168.40.11/255.255.255.0 gw 192.168.30.254 on port 4 PVID 40

ping works in all ways between pc

PC0 can go on the internet and ping 8.8.8.8 and 192.168.1.254

PC30 & PC40 can't go on internet and can't ping 8.8.8.8. or even 192.168.1.254

Adding route 192.168.30.0/255.255.255.0 gw 192.168.0.253 in Internet Router (DD-WRT) helps PC30 to ping 192.168.0.254

Please note that I have already delete 0.0.0.0 / 0.0.0.0 / Nexthop192.168.0.254 Vlan Interfave 1 created by wizard and recreate it manually (instead with the wizard option) and there was no changes .

I didn't define any ACL. The configuration is done after a switch re-initialization .

Same result with port in Hybrid or in Access mode …

Aaaarrrgghhhh ! ;-)

What am i missing ? Thanks for your help !

Some news about my issue.

I change the DDWRt router for an Asus RT-n66u to give a try (same IP/conf without any changes on HP switch...). I put the same route back in IP Static routing of Asus RT like I puttted in Ddwrt  and ... it works !

I had already use Static IP in DDwrt router and works like a charm in other situations... but not this one !

Can someone help with some explainations why it doesn't work with DD-Wrt router in Gateway mode and works with Asus RT in gateway mode too ... 

Thanks for help
