sap web dispetcher redirect option

Dear all

I have SRM system and sap web dispatcher. When i try redirect external adress to internal using sap wd i face with issue "Can not display this page"

My actions.

1) Add profile parameter to SAP WD:

icm/HTTP/redirect_1 = PREFIX=/, FROM=123.12345.ru, FROMPROT=http, FOR=123.12345*, TO=/sap/bc/nwbc, PROT=https, HOST=123.12345.ru, PORT=port_number

AND i add entry to file hosts on my windows pc like this :

<wd_ip.addr> 123.12345.ru
