Please give me some tips how/where to fix this issue. I'm somewhat lost while debugging this EAP stuff with tunnelling and proxying ;)
It's rather complicated after a while. I'm not sure how it can be easily debugged...
Added some functions to make debugging easier and found out the following: There is a call of eaplist_add() in eap_post_proxy(): 541 if ((handler->eap_ds->request->code == PW_EAP_REQUEST) && 542 (handler->eap_ds->request->type.type >= PW_EAP_MD5)) { 543 eaplist_add(inst, handler); and in eaplist_add(): 271 handler->src_ipaddr = handler->request->packet->src_ipaddr; But during proxying handler->request->packet->src_ipaddr.ipaddr.ip4addr is zero: (gdb) p handler->request->packet->src_ipaddr $7 = {af = 2, ipaddr = {ip4addr = {s_addr = 0}, ip6addr = {in6_u = {u6_addr8 = "\000\000\000\000\220\006\030\b\215\b\b\000\000\000", u6_addr16 = {0, 0, 1680, 2072, 36260, 2056, 0, 0}, u6_addr32 = {0, 135792272, 134778276, 0}}}}} Then we're trying to find a session with correct ip address of NAS, i.e. 192.168.2.3 and eaplist_find() fails because it contains session with zero ipaddr. I'll try to debug deeper and figure out how to fix this correctly (and not to break anything else ;) -- Best wishes, Dmitry Sergienko (SDA104-RIPE) Trifle Co., Ltd.
