Unable to connect to SAP Through LAN

[Former Member]

I have installed a new BIW server but i am unable to connect to that sap server thru LAN.

Let me give the IP range of the servers

DEV - 90.0.0.*

PRD - 90.0.0.*

BIW DEV - 90.0.0.* (New BIW server which i am unable to connect)

i am able to connect to DEV and PRD from BIW DEV server. but not vice versa

I tried to ping the BIW IP Address from router machine and i am able to ping.

We have a Router machine. I don't know if i have to add any entry in routtab. I already have p*** in routtab.

Also i am unable to connect to biw dev using router string from external network but able to connect to DEV and PRD.

It will be great if anyone give suggesion to resolve this Issue.

I don't know if this matters or not. If i close the sap router also guys are able to connect to DEV and PRD. but not to BIW DEV.

Please help me resolving this issue

Hi Praxbasis ,

What is the system number of your BW DEV server. Please check if the ports relating to BW Server are opened in the LAN. Hope your network guys can help in this regard as I feel there could be some problem with ports in network firewall.

Thanks for your Reply. My issue is solved. The network Admin assigned the BIW server IPAddress to another client machine.

So there was a conflict. I changed the IP Address and now i am able to connect thru LAN.

Thanks for your reply!!

According to the instructions mention in the link, i ran the test everything was fine..

i ran the self test and i got self test OK.

In the biw server Host file i mentioned the IP address and host name of the biw server and DEV and PRD.

Still unable to connect to BIW Server thru LAN.

when i tried saprouter -r command in the router machine, it gives this error

"routab cannot open './saproutab': EXIT PROGRAM!!!

<running without saproutab is no longer supported for security reasons>

Could not open permission table"

Please guide me what else can be done.

Thanks

Regards

Prakash

If using LAN over DHCP, try static IP,

if issue getting resolved after using static IP, please check your DNS server settings and well configure local DNS in your firewall
